Alopecia Areata Evolution

Alopecia areata evolution

        The Alopecia areata is a chronic condition that often lasts several years, its evolution is unpredictable. Alopecia areata regrowth being often white, hair often takes several months before it can return to normal color. Alopecia areata generally worsens over the years and especially if the alopecia areata is more severe at the time of diagnosis.The long-term prognosis is worse when the alopecia areata starts in childhood and when it touches the edge of the hair.

        Usually the alopecia areata remains localized to the scalp and is restricted to small patches bare. However, in its extensive form, it can grow and extend to the beard and the entire scalp. The Universal Alopecia areata (loss of all body hair) is very rare. The evolution of Alopecia areata is highly unpredictable. Moreover, there is no cure to overcome it. Nothing protects a relapse (which is very common).

        The evolution of Alopecia areata is difficult to predict because the severity and progress vary from one individual to another. However in some individuals alopecia areata may evolve into a total loss of hair of the head: This is alopecia totalis, which is more common in young subjects. A minority lose all their hair and all body hair and Alopecia areata is generalized (Alopecia areata universalis).

        There are also diffuse alopecia areata leading to a decrease in hair density uniformly throughout the scalp. Moreover, the increase is more or less rapid. Thus, when a devastating alopecia areata bursts, all hair can fall in 48 hours. In others the alopecia areata evolves slowly over decades. Some people find a variation in the amplitude of the alopecia areata depending on the season. Hair from different parts of the body can repel independently. During regrowth, the new hair is usually bleached at first, and then it will take the usual color and diameter.
