Alopecia areata is a medical condition characterized primarily by severe hair loss in various parts of the body but mostly involving the scalp. In general, the hair loss is not balanced, leading to spots of bald areas on the head. In some cases, however, although this is very uncommon, baldness may spread all over the scalp.
This condition may be observed in about 1 or 2% of total population, with equal chances of occurring in both men and women. Some earlier researches say that it commonly occurs during early adulthood although more recent ones indicate its potential manifestation in all ages.
By nature, alopecia areata is not transferred through skin contact. It is not similar to contagious skin disorders. Heredity is pointed out to be a major cause, with several cases in the past showing trends of similar condition in the family. Alopecia areata is said to be an autoimmune disorder, where hair follicles are attacked by one’s own body leading to suppression of hair growth. Studies show that T-cell lymphocytes encircle the follicles which lead to inflammation and, consequently, hair loss.
There are also certain environmental factors which are said to cause alopecia areata. High levels of stress or depression are the most common. These factors negatively complement hereditary tendencies and increase the condition’s probability to manifest itself.
Alopecia areata must not be mistaken with simple types of hair loss. Biopsy is often the best way to correctly diagnose if a condition is considered as alopecia areata or not. Once diagnosed, there are various types of treatments available but the sooner it is cured, the easier the hair grows back to normal.
