Hair is comprised mainly of protein, with amino acids making up the building blocks. The hair follicle contains the root of hair, hair papilla for nourishment, matrix with epithelial cells, and hair shaft which emerges from the skin. There are numerous hair disorders that can be diagnosed such as androgenetic alopecia which is the most common cause of hair loss, alopecia areata caused by the immune system attacking hair follicles, and traction alopecia from chronic pulling of hair. Treatment options include oral medications like vitamins, hormones, steroids or anti-inflammatory drugs, topical treatments like minoxidil, hair replacement through transplants or wigs, and behavior modification for disorders caused by certain behaviors.

Hair is comprised of many contributing factors. Proteins,
raw elements, amino acids and bonds work together in
forming hair fiber. The dominant contributor in the
composition of hair is protein, accounting for 91 percent of
hair fiber.
Amino acids, the building blocks of protein, are made up of
COHNS elements, (

8. THERE ARE NUMEROUS HAIR DISORDERS THAT CAN BE DIAGNOSED AND
EVALUATED:
Androgenetic alopecia is the most common form of hair loss. This disorder, also known as
male-pattern or female-pattern hair loss, results in permanent hair loss from the scalp.
Alopecia areata is caused by the immune system attacking hair follicles. As a result, hair falls
out in round patches from anywhere on the body. It typically grows back but may fall out
again.
Traction alopecia describes gradual hair loss that is caused by chronic pulling. Hair that is
forced in certain directions, typically through use of braids, ponytails, barrettes, weaves,
dreadlocks or protective headgear, can result in significant hair thinning. It is particularly
noticeable around the temples and behind the ears.
Diffuse alopecia is hair loss from the scalp caused by nutritional deficiencies, imbalance of
hormones or other physical or emotional stressors.
Chemotherapy-induced alopecia is scalp hair loss that results from chemotherapy, a form of
cancer treatment.
Telogen effluvium (TE) is the second most common form of hair loss, though little is known
about the condition. It is marked by a significant decrease in scalp hair. This condition is
related to diffuse alopecia, and diagnosis can be made once other hair disorders have been
ruled out. In some extreme cases TE can affect other areas such as the eyebrows or pubic
region.
9. ORAL MEDICATION
A range of medications can be used to treat hair disorders:
Vitamin supplements may be recommended for nutritional deficiencies.
Hormone replacement therapy can correct hormone imbalances and restore hair growth.
Oral steroids or anti-inflammatory antibiotics may be prescribed for hair disorders with skin
irritation.
SSRI medication may help to treat underlying mental health issues leading to impulsive hair
pulling.
Topical Treatment
Minoxidil is a topical medication that promotes hair growth in people with androgenetic
alopecia.
Hair Replacement
Some hair disorders cause permanent hair loss and damage the follicles, making future hair
growth impossible. People who have these skin disorders can benefit from hair transplant
surgery or wigs. In some disorders, hair replacement must wait until damaged hair follicles
have healed.
Behavior Modification
Some hair disorders are caused by factors that can be controlled. The behaviors that lead to
hair loss in traction alopecia and trichotillomania can be addressed through education or
therapy.
Editor's Notes
These elements form bonds called side bonds which link together the long chain of amino acids known as the polypeptide chain. This chain forms a helix by creating spiral movement that intertwines.
