Alopecia could be of two types

  • Non scarring Alopecia
  • Scarring Alopecia

Non Scarring Alopecia

In non – scarring alopecia, there is a hair loss but the follicles are spared and hence regrowth of hair is always a possibility.

When the hair loss is in coin shaped types it is called as Alopecia Areata. The bald patches are very distinctive because they are almost sharply defined circular patches. One or several patches of baldness can occur during the time that alopecia areata continues.

The patches may enlarge and overlap or they may remain very small. If left untreated in extreme cases, all the hair from the scalp and face can be lost (Alopecia Totalis) or all hair from the head and body can be lost (Alopecia Universalis)

Scarring Alopecia

Scarring alopecia or cicatrical baldness (cicatric means scar) is a type of baldness where the underlying tissues below and around hair follicles get scarred and hair tissues die off and cannot be rejuvenated and regenerated because hair follicles are destroyed. In scarring Alopecia regrowth is not possible.

Pseudopelade
Pseudopelade is a kind of scarring alopecia. It is characterized by slowly developing patches of baldness in which the hair follicles are also destroyed. Pseudopelade is an auto immune problem. Patches can be seen as ‘footprints on the snow’ showing irregular margins. Hair and scalp are dry to appear. Treatment depends on the severity of the problem. Aim of the treatment is to control further progression of the condition.

Folliculitis Decalvans
Folliculitis decalvans is an inflammatory alopecia that leads to bogginess or indurations of involved parts of the scalp along with pustules, erosions, crusts, and scale. It begins at a central point and spreads outward, leaving scarring, sores, and hair loss in its wake.

This is a commonly found primary scarring alopecia. Folliculitis decalvans has been described as a cicatrical alopecia characterized by erythematous scalp with pustules around the hair follicles, commonly called Folliculitis. Each crop of pustules results in progression of hair loss. Follicle destruction and scarring with permanent hair loss is the end-result of the condition. This disease, affects both men and women. Most often, the crown is the affected area; in rare cases, however, the condition can affect the beard, face and nape of the neck.

The onset of folliculitis decalvans can occur at any time after adolescence. Young and middle aged adults of both sexes can be affected by the disease. The condition progresses slowly and disease activity waxes and wanes periodically.

Discoid Lupus Erythematosus & S.L.E
Discoid lupus erythematosus is a chronic dermatological disease that can lead to scarring, hair loss, and hyper pigmentation changes in skin if it is not treated early and promptly.

Lichen Planopilaris
Lichen Planopilaris is a condition which usually affects the parts of the body that have hair. This condition may eventually lead to hair loss which may be permanent, it may also cause scarring and inflammation. This condition appears as if you have pimples only in their case the pimple are reddish in colour and they are usually very itchy. This condition may also cause the skin to appear uneven and rough.
