2. WHAT IS HAIRLOSS?
Hair loss, also known
as alopecia or baldness, refers to a loss
of hair from part of the head or
body. Typically at least the head is involved.
The severity of hair loss can vary from a
small area to the entire body.
Typically inflammation or scarring is not
present. Hair loss in some people
causes psychological distress
Average Hair loss =100-150 hair strands
per day.
Alarming Hair loss is >150 hair strands per
day.

3. TYPES OF HAIR LOSS
Involution alopecia-is a natural
condition in which the hair gradually
thins with age.
Alopecia areata often starts suddenly
and causes patchy hair loss in children
and young adults. This condition may
result in complete baldness (alopecia
totalis). But in about 90% of people
with the condition, the hair returns
within a few years

4. Types of hair loss cont..
Alopecia universalis causes all body hair
to fall out, including the eyebrows,
eyelashes, and pubic hair.
Trichotillomania, seen most frequently in
children, is a psychological disorder in
which a person pulls out one's own hair.
Telogen effluvium is temporary hair
thinning over the scalp that occurs
because of changes in the growth cycle of
hair. A large number of hairs enter the
resting phase at the same time, causing
hair shedding and subsequent thinning.

5. ANDROGENIC ALOPECIA
MALE PATTERN
BALDNESS
• suffers hair loss as early as
their teens or early 20s.
• It's characterized by a receding
hairline and gradual
disappearance of hair from the
crown and frontal scalp.
FEMALE PATTERN
BALDNESS
• noticeable thinning until their
40s or later.
• It's characterized by general
thinning over the entire scalp,
with the most extensive hair
loss at the crow

Infection

7. PATHOPHYSIOLOGY
• Hair follicle growth occurs in cycles.
Each cycle consists of a
long growing phase (anagen),
short transitional phase (catagen)
short resting phase (telogen).
• At the end of the resting phase, the
hair falls out (exogen) and a new
hair starts growing in the follicle
beginning the cycle again.
CATAGEN-
Transitional hair
growth that
lasts two to
three weeks
TELOGEN- Resting phase
that lasts about two to
three months.
ANAGEN- Active
hair growth that
last between
two to six years

8. DIAGNOSIS
• The pull test
• The pluck test
• Scalp biopsy
• Daily haircounts
• Trichoscopy

9. MANAGEMENT
• Minoxidil
• Finasteride
• Corticosteroids
• Immunosuppressants
• Anthralin
• Hormonal modulators
1. MEDICATIONS

10. • Follicle transplants
 Strip harvesting.
 Follicular unit extraction (FUE)
 Follicular unit transplant.
 Robotic hair restoration.
• Scalp flaps
2. SURGERY

11. 3. ALTERNATIVE MEDICINE
• Dietary supplements are not
typically recommended. There is
only one small trial of saw
palmetto which shows tentative
benefit in those with mild to
moderate androgenetic
alopecia. There is no evidence
for biotin. Evidence for most other
produces is also insufficient. There
was no good evidence
for gingko, aloevera, ginseng, berg
amot, hibiscus, or sorphora as of
2011.
