Hair is an important part of who we are. The average person has 5 million hairs (100,000 – 150,000 are on the scalp). Blonds usually have more hair (about 140,000 hairs), brunettes have slightly higher than average hair (about 105,000 hairs), and redheads have a little less than average (about 90,000 hairs). Hair is composed of keratin, the same protein that nails and the outer layer of skin is made of. Hairs are produced by a small structure underneath the skin called the hair follicle.
Hair follicles are formed while we are still a fetus, and after we are born no new follicles are produced. Hair growth is often regulated by hormones within the body. At puberty, certain male hormones trigger the growth of pubic, underarm, and beard hairs. They can also trigger the start of genetic male pattern hair loss.
Each hair grows in a series of phases. In the growth phase, the hair is continually growing for up to five years. At the end of the growth cycle, there is a transitional phase where the hair does not grow and begins to change into the third phase. The third phase is the resting phase. During this phase, the follicle is no longer growing, and at the end the old hair is pushed out, then the cycle starts over and a new growth phase starts. This happens repeatedly throughout our lives, and is why even people unaffected with hair loss lose 50-100 hairs per day.
In people affected with genetic hair loss, there appears to be a higher number of hormone receptors in the areas of the scalp with hair loss. In most people affected by hair loss, male hormone levels are the same as in normal people, but because there are more receptors in the balding areas of the scalp they are affected as if their hormone levels were higher than normal. Researchers are still working on how the presence of a certain male hormone, Dihydrotestosterone (DHT), causes damage to follicles in people with genetic hair loss. As the follicles are damaged, the hairs grown are thinner and the growth cycles are shorter with each new growth cycle, until eventually no hair or a small, miniaturized hair is all that can be produced. As more and more hairs become smaller and more miniaturized, the person appears balder.
Genetic hair loss causes about 95% of all hair loss. Another main cause is an autoimmune condition known as Alopecia Areata (patchy hair loss), Alopecia Totalis (loss of all hair on the head), and Alopecia Universalis (loss of all hair on the body). Researchers are also working on a treatment for this condition. Other causes include hair loss due to side effects of medication, stress, or dietary deficiency.
Alopecia refers to hair loss on the scalp or other areas. There are several forms including alopecia areata (patchy hair loss), totalis (total scalp hair loss), and universalis (total body hair loss). Androgenetic alopecia is a hereditary pattern of hair thinning. Scarring alopecias permanently damage hair follicles. While hair loss may be temporary, treatments aim to prevent further loss by addressing underlying causes or using drugs like minoxidil, finasteride, or corticosteroids. Wigs are also an option for cosmetic reasons.
This document discusses therapeutics for alopecia (hair loss). It begins by describing hair anatomy and the hair growth cycle. It then discusses the causes and types of alopecia, including telogen effluvium, anagen effluvium, androgenic alopecia, alopecia areata, alopecia totalis, alopecia universalis, and cicatrical alopecia. Diagnostic techniques and general management approaches are also covered. The document concludes by describing several homeopathic remedies that can be used to treat different types and causes of alopecia, including phosphorus, flouroic acid, lycopodium, arnica, staphysagria
Alopecia is defined as hair loss from areas where hair normally grows. There are several types of alopecia including alopecia areata (patchy hair loss), alopecia totalis (total hair loss of the scalp), alopecia universalis (total hair loss of the entire body), and androgenetic alopecia (male or female pattern baldness). Causes can include autoimmune conditions, certain medications, medical conditions, radiation/chemotherapy, and genetics. Diagnosis involves history, physical exam, and sometimes blood tests. Treatment options include minoxidil, finasteride, corticosteroid injections, wigs, hair transplants, massage, and UV light therapy.

Alopecia Areata is A localized loss of hair in round or oval areas with no apparent inflammation of the skin
Prognosis: good for limited involvement. Poor for extensive hair loss.
Management: intralesional triamcinolone effective for limited number of lesions
The document discusses various types of hair loss including:
- Androgenic alopecia (male and female pattern baldness) which is influenced by hormones and genetics.
- Alopecia areata which causes patchy hair loss and may result in complete baldness. It often affects children and young adults.
- Telogen effluvium which is a temporary form of hair thinning caused by a large number of hairs entering the resting phase at the same time.
- Treatments discussed include minoxidil, finasteride, hair transplants, and targeting the underlying cause for conditions like telogen effluvium.
Alopecia Areata is a nonscarring type of hair loss that can present in different patterns. The cause is unknown but may be autoimmune, genetic, or related to infection or emotional stress. It is characterized by acute onset patches of hair loss on the scalp or other hair-bearing areas. Diagnosis is usually clinical but biopsy can be done. Treatment options include local or systemic steroids, but regrowth can take time and recurrence is possible. Prognosis is worse in cases of early onset, severe disease, family history of alopecia areata, or nail involvement.

Alopecia areata is a condition that causes patchy hair loss on the scalp or other parts of the body. It is caused by an autoimmune response where the immune system attacks hair follicles, preventing them from producing hair. Alopecia areata can be associated with other autoimmune diseases and may run in families. It affects both adults and children and causes psychological distress, though hair typically grows back eventually, though it may fall out again later.
Disorders of hair can be divided into several categories:
1) Non-scarring alopecia includes androgenetic alopecia (male and female pattern baldness) and diffuse thinning. Treatment includes minoxidil, finasteride, and hair transplantation.
2) Endocrine and nutrition related disorders are caused by issues with the thyroid, pituitary, adrenals, or nutrient deficiencies.
3) Telogen effluvium occurs after stress like fever, childbirth, surgery or drugs and causes hair shedding after 3 months.
4) Drug induced hair loss can be caused by medications like thallium, heparin, and vitamin A.
This document provides information about a patient presenting with hair loss. It discusses taking a history of the hair loss including duration, onset, pattern, associated symptoms, medical history, drug history, and family history. It then discusses examining the scalp and different evaluation techniques to assess hair loss such as daily hair counts, hair pull tests, trichograms, and scalp biopsies. Causes of hair loss are explored such as telogen effluvium, chronic telogen hair loss, alopecia areata, traction alopecia, and androgenetic alopecia. Treatment options for telogen effluvium such as minoxidil, dietary supplements, and reassurance are mentioned. Finally, female and

1) Hirsutism is defined as excessive terminal hair growth in androgen-dependent areas of the body in women, which grows in a typical male distribution pattern. It is often caused by androgen overproduction or increased sensitivity to androgens. Diagnosis is usually clinical and confirmed with laboratory testing. Treatment options include oral contraceptives, spironolactone, and anti-androgens.
2) Alopecia areata is an autoimmune disease causing patchy, non-scarring hair loss. It affects the scalp and sometimes other hair-bearing areas. Treatment focuses on reducing inflammation and regrowth of hair. Options include topical corticosteroids, immunotherapy, and supportive
Hair diseases are disorders primarily associated with the follicles of the hair. Many hair diseases can be associated with distinct underlying disorders. Hair disease may refer to excessive shedding or baldness (or both). Balding can be localized or diffuse, scarring or non-scarring.

Telogen effluvium is a nonscarring, noninflammatory form of hair loss caused by an abnormal number of hairs entering the telogen or resting phase after a physiologic or emotional stressor. It presents with diffuse shedding of scalp hair three to five months after the inciting event. The diagnosis is usually made based on history and clinical findings. No treatment is needed as it is self-limited, usually resolving within six months once the underlying stressor is removed.
This document discusses various types and causes of hair loss. It begins by classifying hair loss as scarring vs nonscarring, and diffuse vs localized. Nonscarring hair loss can be caused by telogen effluvium (the most common cause), anagen effluvium, androgenetic alopecia, etc. Triggers of telogen effluvium include stress, medical conditions, nutritional deficiencies, and certain drugs. Evaluation involves history, examination including pull test and trichogram, and basic lab tests. Treatment focuses on identifying and removing triggers when possible as well as medications for specific conditions like minoxidil for androgenetic alopecia.
This document discusses the anatomy, physiology, and common conditions of hair and nails. It begins by classifying hair types and describing the hair growth cycle. It then discusses specific hair and nail conditions like alopecia areata, androgenetic alopecia, telogen effluvium, hirsutism, hypertrichosis, nail changes due to trauma or systemic disease, and nail infections. Throughout, it provides details on causes, presentations, courses, treatments, and differentials for each condition.
Diffuse hair loss in women is a common complaint that requires a systematic evaluation. The diagnosis involves a detailed history, scalp examination, hair pull test, blood tests, and sometimes a scalp biopsy. Hair follicle cycling is influenced by internal and external factors, and all types of hair loss except scarring alopecia represent disorders of this cycle. The main differential diagnoses for diffuse female hair loss are telogen effluvium, female pattern hair loss, diffuse alopecia areata, dystrophic anagen effluvium, and psychogenic pseudoeffluvium. Trichoscopy can help differentiate between these conditions by examining hair characteristics. A thorough evaluation is needed since the causes of diffuse female hair loss can
This document summarizes disorders of hair, including less or excessive hair growth. It describes the three parts of hair - the bulb, root, and shaft. It classifies hair into lanugo, vellus, and terminal hair and discusses their characteristics. The hair cycle of growth, catagen, and telogen phases is explained. Types of alopecia such as alopecia areata, androgenetic alopecia, and telogen effluvium are described. Hirsutism and hypertrichosis are also briefly covered.

Androgenetic alopecia (AGA), or male/female pattern baldness, is associated with increased cardiovascular risk. AGA affects around 50% of men and up to 75% of women over age 65. Studies have found higher rates of hypertension, diabetes, dyslipidemia, metabolic syndrome, and carotid plaques in those with AGA. The risk increases with earlier onset and severity of hair loss. Pathogenic mechanisms may include hyperinsulinemia, which promotes metabolic syndrome, vasoconstriction, and hair follicle miniaturization, as well as hyperaldosteronism, which can cause hypertension and stimulate mineralocorticoid receptors in the skin.
The document discusses different types of hair loss including alopecia, androgenetic alopecia in men and women, traction alopecia, and their causes and treatments. It describes the hair growth cycle and tests used to evaluate hair loss. Common treatments for androgenetic alopecia include minoxidil, finasteride, and spironolactone depending on the patient's sex and symptoms. Traction alopecia is caused by hairstyles that pull on hair and can be prevented by less tight styling.

The document discusses male pattern baldness, also known as androgenetic alopecia, which accounts for over 95% of hair loss in men. By age 35, two-thirds of men experience some hair loss and by age 50, around 85% have significantly thinning hair. The document outlines the causes of male pattern baldness, which is generally due to a genetic sensitivity to dihydrotestosterone (DHT). DHT shrinks hair follicles over time, eventually stopping hair production. The document provides information on diagnosing male pattern baldness and treatments that have been proven effective, such as Propecia.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

PHYSICAL EXAMINATION
The physical examination should focus
on the hair and scalp, but attention should
be given to physical signs of any comorbid
disease indicated by the review of systems.
If only the scalp is involved, the physician
shouldlookfortypicalmaleorfemalepattern
to determine the presence of androgenetic
alopecia. Whole body hair loss is consistent
with alopecia totalis. Dry, broken hair sug-
gests trichorrhexis nodosa, whereas scaling,
pustules, crusts, erosions, or erythema and
local adenopathy suggest infection.
The pull test may be used to diagnose
hair loss conditions.1
The examiner grasps

Family history of hair loss; gradually progressive course
Men: bitemporal thinning of the frontal and vertex
scalp, complete hair loss with some hair at the
occiput and temporal fringes
Women: diffuse hair thinning of the vertex with
sparing of the frontal hairline
Men: topical minoxidil (2% or 5% solution)
Women: topical minoxidil (2% solution)
Treatment should continue indefinitely because hair loss
reoccurs when treatment is discontinued
Adverse effects include hypertrichosis (excessive hair growth
for age, sex, and race) and irritant or contact dermatitis
Telogen
effluvium
Clumps of hair come out in the shower or in
hairbrush; associated with physiologic or emotional
stress
Treatment involves removing the underlying cause and
providing reassurance
Condition is usually self-limited and resolves within two to
six months
Tinea capitis Dermatophyte infection of the hair shaft and follicles;
patients present with patchy alopecia with or
without scaling
Requires systemic treatment because topical antifungals
do not penetrate hair follicles

(Sporanox), fluconazole (Diflucan), or griseofulvin
Microsporum species: griseofulvin
Trichorrhexis

Hairs break secondary to trauma or because of fragile
hair (congenital or genetic); causative traumas
include excessive brushing, heat application,
hairstyles that pull on hairs, and conditions that
cause excessive scalp scratching

approximately 40 to 60 hairs at their base
using the thumb, index, and middle fingers
and applies gentle traction away from the
scalp. A positive result is when more than
10% of hairs (four to six) are pulled from
the scalp; this implies active hair shedding
and suggests a diagnosis of telogen efflu-
vium, anagen effluvium, or alopecia areata.
However, a negative test result does not nec-
essarily exclude those conditions. The pull
test is difficult to standardize because the
pulling force is not distributed uniformly
and because it is difficult to approximate the
number of hairs grasped, thereby leading to
false interpretations.
LABORATORY STUDIES
Because many conditions can cause hair loss,
there are no routine tests to evaluate hair
loss. Laboratory testing is indicated when
the history or physical examination findings
suggest an underlying comorbidity.
Table 2. Common Findings, Related Diagnoses, and Workup for Hair Loss
Common findings Related diagnosis Diagnostic workup and comments
Abrupt onset of hair loss Telogen effluvium related to a specific event Inquire about inciting event

Specific Disorders
ANDROGENETIC ALOPECIA
Androgenetic alopecia is the most common
form of hair loss in men and women and is a
normal physiologic variant. It is most preva-
lent in white men, with 30%, 40%, and 50%
experiencing androgenetic alopecia at 30, 40,
and 50 years of age, respectively 2
(Figure 1).
Although this condition is less common in
women, 38% of women older than 70 years
may be affected3
(Figure 2 4
). Many patients
with androgenetic alopecia have a family
history of this condition.
Hair thinning occurs in a sex-specific pat-
tern. Men typically present with bitemporal
thinning, thinning of the frontal and vertex
scalp, or complete hair loss with residual hair
at the occiput and temporal fringes.5
Women
typically present with diffuse hair thinning
of the vertex with sparing of the frontal
hairline. Some women experience thinning
over the lateral scalp. Common conditions
that mimic androgenetic alopecia include
thyroid disease, iron deficiency anemia, and
malnutrition.
Treatment is based on patient preference.
Topical minoxidil (2% or 5% solution) is
approved for the treatment of androgenetic
alopecia in men. Hair regrowth is more robust
at the vertex than in the frontal area, and will
take six to 12 months to improve.5
Treatment
should continue indefinitely because hair
loss reoccurs when treatment is discontin-
ued. Minoxidil 2% solution is recommended
for the treatment of androgenetic alopecia in
women.6
Adverse effects include irritant and
contact dermatitis.
Finasteride (Propecia), 1 mg per day orally,
is approved to treat androgenetic alopecia in
men for whom topical minoxidil has been
ineffective. Adverse effects of finasteride
include decreased libido, erectile dysfunc-
tion, and gynecomastia.7
Minoxidil and oral finasteride are the
only treatments currently approved by the
U.S. Food and Drug Administration for the
treatment of androgenetic alopecia. Both of
these drugs stimulate hair regrowth in some
men, but are more effective in preventing
progression of hair loss. Although there are a
number of other treatments listed in various
texts, there is not good evidence to support
their use.8
ALOPECIA AREATA
Alopecia areata is an acute, patchy alope-
cia that affects up to 2% of the population
with no difference between sexes 9
(Figure 3).
Approximately 20% of affected patients are
children.10
The etiology is unknown, but the
pathogenesis is likely autoimmune. Patients
may have a single episode, or they may have
remission and recurrence. The diagnosis can

usually be made clinically.
Hair loss in alopecia areata occurs in three
different patterns: patchy alopecia is circum-
scribed, oval-shaped, flesh-colored patches
on any part of the body; alopecia totalis
involves the entire scalp; and alopecia uni-
versalis involves the whole body. Evaluation
of the scalp may reveal short vellus hairs,
yellow or black dots, and broken hair shafts
(which are not specific to alopecia areata).
Microscopic examination of the hair follicles
demonstrates exclamation mark hair (i.e.,
hairs that are narrower closer to the scalp and
mimic an exclamation point; Figure 4
4
). Nail
pitting is also associated with alopecia areata.
Treatment for adults with less than 50% of
scalp involvement is intralesional triamcino-
lone acetonide injected intradermally using a
0.5-inch, 30-gauge needle. Maximal volume
is 3 mL per session.11
Treatment may be
repeated every four to six weeks until resolu-
tion or for a maximum of six months. Local
adverse effects include transient atrophy and
telangiectasia.
Other therapies for the treatment of alope-
ciaareataincludetopicalmid-tohigh-potency
corticosteroids, minoxidil, anthralin, immu-
notherapy (diphenylcyclopropenone, squaric
acid dibutylester), and systemic corticoste-
roids.12
Currently available therapies often
yield unsatisfactory results, and some clini-
cians rely on the high rate of spontaneous
remission or recommend a hairpiece or wig
if remission does not occur.13
TINEA CAPITIS
Tinea capitis is a dermatophyte infection
of the hair shaft and follicles that primarily
affectschildren(Figure5).Riskfactorsinclude
household exposure and exposure to contam-
inated hats, brushes, and barber instruments.
Trichophyton tonsurans is the most common
etiology in North America.14
Transmission
occurs person-to-person or from asymptom-
atic carriers. Infectious fungal particles may
remain viable for many months; other vectors
include fallen infected hairs, animals, and
fomites. Microsporum audouinii is commonly
spread by dogs and cats.
Patients with tinea capitis typically present
with patchy alopecia with or without scaling,
although the entire scalp may be involved.
Otherfindingsincludeadenopathyandpruri-
tus. Children may have an associated kerion,
a painful erythematous boggy plaque, often

with purulent drainage and regional lymph-
adenopathy. Posterior auricular lymphade-
nopathy may help differentiate tinea capitis
from other inflammatory causes of alopecia.
If the diagnosis is not clear from the history
and physical examination, a skin scraping
taken from the active border of the inflamed
patch in a potassium hydroxide prepara-
tion can be examined microscopically for
the presence of hyphae. Skin scrapings can
also be sent for fungal culture, but this is less
helpful because the fungi can take up to six
weeks to grow.
Tinea capitis requires systemic treat-
ment; topical antifungal agents do not pen-
etrate hair follicles. If the causative agent is
a Trichophyton species, treatment options
include oral terbinafine (Lamisil), itracon-
azole (Sporanox), fluconazole (Diflucan),
and griseofulvin.15
These agents have similar
efficacy rates and potential adverse effects,
but griseofulvin requires a longer treatment
course. Griseofulvin is the preferred treat-
ment for infections caused by Microsporum
species, but definitive studies are lacking.15,16
There are limited data about empiric treat-
ment before culture results are available.
Because griseofulvin may have lower cure
rates in the treatment of T. tonsurans infec-
tions, it may not be as effective when used
empirically.15
All close contacts of patients
with tinea capitis should be examined for
signs of infection and treated, if necessary.
TELOGEN EFFLUVIUM
Telogen effluvium is a nonscarring, nonin-
flammatory alopecia of relatively sudden
onset, with similar incidences between sexes
and age groups. It occurs when large num-
bers of hairs enter the telogen phase and fall
out three to five months after a physiologic
or emotional stressor. The list of inciting fac-
tors is extensive and includes severe chronic
illnesses, pregnancy, surgery, high fever, mal-
nutrition, severe infections, and endocrine
disorders. Causative medications include
retinoids, anticoagulants, anticonvulsants,
beta blockers, and antithyroid medications;
discontinuation of oral contraceptive agents
is another possible cause.17
Patients with telogen effluvium may have
symptoms of an underlying condition, but
are often asymptomatic. They often notice
clumps of hair coming out in the shower
or in their hairbrush. They should be asked
to recall any potential trigger two to five
months before the onset of the condition.
Examination of the scalp in patients with
telogen effluvium typically shows uniform
hair thinning. The presence of erythema,
scaling, or inflammation; altered or uneven
hair distribution; or changes in shaft caliber,
length, shape, or fragility may suggest other
diagnoses. Laboratory investigations are indi-
cated if the history and physical examination
findings suggest underlying systemic disor-
ders (e.g., iron deficiency anemia, zinc defi-
ciency, renal or liver disease, thyroid disease).
Telogen effluvium is usually self-limited
and resolves within two to six months. Treat-
ment involves eliminating the underlying
cause and providing reassurance. Potentially
causative medications should be discontin-
ued, if possible. Telogen effluvium may last
for years if the underlying stress continues.
TRICHOTILLOMANIA
Trichotillomania is an impulse-control dis-
order with a mean age of onset of approxi-
mately 13 years (Figure 6). Patients with this
condition consciously or unconsciously pull,
twist, or twirl their hair. Trichotillomania is
reported to affect as much as 4% of the pop-
ulation, with the highest incidence in child-
hood and adolescence.18
Trichotillomania may be difficult to diag-
nose if the patient is not forthcoming about
pulling at his or her hair. Patients typically
Figure 6. Hair loss from trichotillomania.
8. Hair Loss
September 15, 2017 ◆
Volume 96, Number 6 www.aafp.org/afp American Family Physician 377
present with frontoparietal patches of alope-
cia that progress posteriorly and may include
the eyelashes and eyebrows. Bare patches are
typical, and the hair may appear uneven,
with twisted or broken off hairs. Trichotil-
lomania may lead to problems with self-
esteem and social avoidance. Complications
include infection, skin damage, and perma-
nent scarring.18
The optimal treatment for this condition is
not known, and psychiatric referral may be
indicated. Treatment options include cogni-
tive behavior therapy
19
and selective sero-
tonin reuptake inhibitors, although strong
evidence of a treatment effect has not been
demonstrated. Preliminary evidence suggests
positive treatment effects with acetylcysteine,
olanzapine (Zyprexa), and clomipramine
(Anafranil).19
A combination of cognitive
behavior therapy and medications may be
more effective than either approach alone.19
TRICHORRHEXIS NODOSA
Trichorrhexis nodosa occurs when hairs
break secondary to trauma or because of frag-
ile hair (Figure 7). It affects the proximal hair
shaft, although the distal shaft may also be
involved.20
Causative traumas include exces-
sive brushing, heat application, tight hair-
styles, trichotillomania, and conditions that
cause excessive scalp scratching. Chemical
traumas include harsh hair treatments (e.g.,
excessive use of bleach, dye, shampoo, perms,
or relaxers21
) and excessive exposure to salt
water. Examples of congenital or genetic
conditions that may cause trichorrhexis
nodosa include trichorrhexis invaginata
(bamboo hair), intussusception of the hair
shaft at the keratinization zone, Menkes dis-
ease, keratinization defects due to defective
copper metabolism, and argininosuccinic
aciduria.22
Rarely, trichorrhexis nodosa can
be a manifestation of hypothyroidism.23
On examination, hairs appear to have
white nodes; on closer inspection, these are
shown to be fracture sites along the shaft and
cortex that have split into several strands. On
dermoscopy, hairs look like two brooms or
paint brushes thrust together.
If the diagnosis is not clear, laboratory
testing should include a complete blood
count, iron studies, copper level, liver func-
tion testing, thyroid-stimulating hormone
level, and serum and urine amino acid levels.
Treatment includes avoiding or minimizing
physical and chemical trauma.
ANAGEN EFFLUVIUM
Anagen effluvium is abnormal diffuse
hair loss (usually abrupt) during the ana-
gen phase due to an event that impairs the
mitotic or metabolic activity of the hair folli-
cle. The incidence of anagen effluvium after
chemotherapy is approximately 65%24
; it is
most commonly associated with cyclophos-
phamide, nitrosoureas, and doxorubicin
(Adriamycin). Other causative medications
include tamoxifen, allopurinol, levodopa,
bromocriptine (Parlodel), and toxins such
as bismuth, arsenic, and gold. Other medi-
cal and inflammatory conditions, such as
mycosis fungoides or pemphigus vulgaris,
can lead to anagen effluvium.25
Patients typically present with diffuse hair
loss that begins days to weeks after exposure
to a chemotherapeutic agent and is most
apparent after one or two months.26
Approx-
imately 50% of women with cancer consider
hair loss to be the most traumatic aspect of
chemotherapy and nearly 10% would decline
treatment for fear of hair loss.26,27
Anagen effluvium is usually reversible,
with regrowth one to three months after ces-
sation of the offending agent. Permanent alo-
pecia is rare. A large meta-analysis of clinical
trials concluded that scalp cooling was the

only intervention that significantly reduced
the risk of chemotherapy-induced anagen
effluvium.27
However, scalp cooling should be
