Alopecia

Alopecia is a hair loss disorder that can affect all hair-bearing skin and is characterized by localized areas of non-scarring hair loss.
It occurs when human immune system mistakenly attacks hair follicles of men and women, which is where hair growth begins. Fortunately the damage to the follicle is usually not permanent. Alopecia occurs in males and females of all ages, but it mostly occurs in childhood.
There are several types of Alopecia: Alopecia Areata, Alopecia Totalis and Alopecia Universalis.

Male Alopecia

Alopecia is one of the most common forms of male hair loss and is distinctly recognized in which hair across the top of the scalp is progressively lost. It takes a pattern of an “M” shape, as hair loss occurs on the temples and crown of the head.
During puberty, coinciding with the same hormonal changes that produce facial & body hair, muscle bulk and deepening voice, promote follicular reduction and gradual hair thinning.
Over time the remaining hair follicles across the top of the scalp are affected, resulting in complete baldness.

Female Alopecia

Women may experience alopecia at some point in their life. Female hair loss occurs with gradual thinning in the central and frontal scalp regions. Medical conditions that spur female alopecia include ovarian abnormalities, menstrual irregularities, acne, and infertility to alopecia.

Androgenic alopecia in women are acquired alopecia resulted from metabolic/ hormonal compensatory mechanisms. Other common causes of female alopecia are nutritional: low iron levels and metabolic disorders.
