Hair loss is the thinning and eventual loss of hair on the scalp, although there are also cases wherein it occurs in the other parts of the body. It is medically known as alopecia. Alopecia may be temporary or permanent and comes in different forms. The most common form of hair loss occurs gradually and is called androgenetic alopecia or “male pattern baldness” that is caused by a combination of hormones and genetics. The amount and patterns of baldness vary and those types include alopecia areata that comes in patches but eventually grow back, telogen effluvium which is more rapid and comes with fever or sudden weight loss, and traction alopecia which is the thinning of hair from pressure used on hair styles. In total, hair loss normally occurs in both sexes, men and women, but is typically move visible and pronounced in men.
