Normally, hair grows at a rate of about half an inch every month. The growth continues for two to six years after which the hair goes into a resting period. It then falls out after this and new hair grows back in its place. Thus, hair loss is actually part of the normal cycle. Female baldness occurs when new hair fails to grow back in the empty follicles. After a period of time, some of the hair follicles even die, while others become incapable of producing or maintaining normal growth of hair.
Some women are genetically prone to hair loss than others. A number of hormones disturb the normal hair growth cycle and the result is thinning hair. These hormones are called testosterone, dihydrotestosterone or DHT and androstenedione. The hormones are actually male hormones but they can also be found in the female body in lesser concentrations.
Pattern Hair Loss in Women
Medical practitioners usually refer to female baldness as female pattern hair loss. However, this is a broad category, which indicates that there are many causes that are related to it. These can include hormone receptors and enzyme blockers. Since the pattern is normally diffused, you can find it encircling the top of a woman’s head. Sites for hormone receptor sites and enzymes also differ on various places of the scalp.
Other causes
Because of the variety of causes, it is important for women who are suffering from substantial loss of hair to get the right diagnosis pertaining to their condition. They should find out if there is any underlying medical condition that is causing female baldness and which could be treated first. This can be determined by having a blood test or if required, a biopsy of the scalp.
