Most Common

Androgenetic alopecia, better known as male pattern baldness and female pattern baldness, is the most common form of hair loss. Characterized by the pattern it produces on the scalp, men will typically notice their hair line receding into the shape of an “M”, while women will usually see a thinning of their hair all over or a widening of their part.

Alopecia areata is thought to be an autoimmune condition where the immune system incorrectly attacks the hair follicle. The affected follicle eventually stops growing visible hair, resulting in circular patches of hair loss across the scalp. Alopecia areata may occur in multiple family members, suggesting genetics play a part in this condition.


Ophiasis is a form of alopecia areata that occurs in a wave or band pattern around the edge of the scalp, typically at the back of the head.


Alopecia totalis, another form of alopecia areata, results in the complete loss of scalp hair. Click on the condition to view an example of alopecia totalis.


Alopecia universalis, an advanced form of alopecia areata, is characterized by the total loss of hair on the scalp and body. Click on the condition to view an example of alopecia universalis.


Chignon alopecia is a form of localized traction alopecia that results in hair loss around the crown of the head. Wearing hair in a tight bun over an extended period of time can cause this condition because of the style’s constant pulling on the hair.


Trichotillomania is an impulse control disorder that drives individuals to compulsively pull out their own hair, resulting in noticeable hair loss. Click on the condition to view an example of trichotillomania.


Traction alopecia results from damaged hair follicles due to constant tension or pulling over a long period of time. Hairstyles such as tight pony tails, buns, braids, or hair extensions can cause traction alopecia. Click on the condition to view an example of traction alopecia.


Hypotrichosis is a condition where there is no hair growth from the time of birth. Rather than starting with hair and losing it over time, people with hypotrichosis never grow any hair.


Anagen effluvium is the sudden loss of hairs in their anagen (growing) phase. This condition may be caused by exposure to chemicals or toxins such as those found in chemotherapy or radiation for cancer treatment. The condition is generally reversible and hair typically regrows within 1-3 months, but some hair loss can be permanent.


Telogen effluvium occurs when hair follicles are prematurely pushed into the telogen, or resting, phase of hair growth. This condition is usually due to an acute environmental factor such as physical trauma, surgery, major illness, or other intense stressors on the body.

Central centrifugal cicatricial alopecia, or CCCA, is a form of scarring alopecia that is common in African-American women, though it can present in men and women of all ethnicities. Research suggests CCCA may be due to a genetic predisposition and may also be linked to harsh styling practices such as relaxers and the use of hot tools.

Lichen planopilaris is a form of lichen planus, a skin disease, and primarily affects the scalp. Lichen planopilaris is characterized by small red pimples around clusters of hairs, causing increased shedding.


Cicatricial alopecia, also called scarring alopecia, refers to a group of rare disorders that destroy hair follicles and replace them with scar tissue. This scar tissue results in permanent hair loss.


Folliculitis occurs when hair follicles are blocked or damaged. Often the damaged follicles become infected with bacteria causing a rash, itching and pimples to appear. In severe cases, hair loss and scarring can occur.


Trichorrhexis nodosa is characterized by weak points or nodes present along the hair shaft. The nodes cause hair to break easily leading to the appearance of thinning hair or patchy hair loss.
