An Introduction And Types Of Hair Loss
Individual hairs do not grow continuously. Rather, each hair follicle (the tiny cavity from which a hair emerges) goes through an anagen, or growth, phase, followed by a telogen, or resting, phase. After the telogen phase, the hair is shed and the process begins again. It is normal to lose up to fifty scalp hairs a day as the follicles go through their cycles. However, if enough follicles fail to produce new hairs after the old ones have been shed, or if the hair produced is weak and brittle, noticeable thinning and/or loss of hair can result. Provillus is the natural hair loss treatment. It helps to grow hair in less than 30 days.
Doctors usually divide types of hair loss-medically termed alopecia-into two categories: scarring and non scarring forms. The scarring forms tend to be less reversible. They usually result from infection that causes inflammation around hair follicles, which eventually leads to the follicles being replaced by scar tissue. Deep bacterial and fungal infection (such as ringworm) can lead to this type of hair loss, as can infection with the herpes zoster virus. A culture of scalp tissue, usually taken at the border of the problem area, and examination of other damaged skin areas may be done to track down the organism responsible for infection and guide in treatment. Scarring alopecia can also result from physical trauma such as abrasive, chemical, or thermal burns.
