Hair Loss

Various Patterns of hair loss:

Hair loss can be present in various forms like:

1) Alopecia Areata: This type of hair loss is the auto immune related form. In this form, the immune cells of the body mistake the hair cells as a foreign body and start destroying them. In this pattern, the hair loss occurs in patches / spots. It is common in people below 20 years of age.

2) Baldness / Alopecia Totalis: In this pattern, the entire scalp loses hair.

3) Telogen Effluvium: In this pattern, the hair goes on thinning and diffuse hair loss occurs due to early entry of hair in telogen phase.

4) Androgenetic Alopecia (includes Male pattern baldness and Female pattern baldness): This type of baldness is caused by genetic and hormonal factors. Male pattern baldness is the most common type of hair loss in men in which the hairline gets receded backwards. This is in turn followed by thinning and loss of hair on the top (vertex) and sides (temple) of the scalp. In Female pattern baldness, there is thinning of hair on top of the scalp, and is less severe than in males.
