Androgenetic alopecia is the most common form of hair loss; studies show that 98 per cent of men who experience balding discover that their condition is caused by Androgenetic alopecia.
The male hormones that are involved in the mechanism of Androgenetic alopecia are called androgens. These androgens cause hair loss for a number of reasons;
• The androgens interact with specific receptors found on cell membranes or inside cells.
• Several forms of the hormone can affect the hair follicles, different areas of the skin respond to the hormone in various ways
• An example of this is how hairs located on the arm pit respond to the hormones by growing, whereas hairs in the scalp fall out in response to them.
This type of alopecia is often found in men and is commonly known as male pattern baldness however the condition is found in women too.
The same proportion of women experience hair loss as men. There are differences in the way that we lose hair between the two sexes.
Female pattern baldness expresses itself as a general thinning of the hair, rather than a balding crown and receding hair line at the temples- as seen in men.
The condition is genetic, and is not thought to be affected by outside influences or changes in external factors such as stress of illness.
All men and women have the hormones that cause hair loss within their bodies, but not all of them develop baldness. This could be because of a number of reasons including;
• People who have Androgenetic hair loss have a higher number of androgen receptors in a single hair follicle
• The hair follicles of someone with Androgenetic hair loss have a higher sensitivity to androgens
Treatments for Androgenetic alopecia are made readily available for men however, treatment for women is not as easy to obtain. This is due to the hormones contained within the medication, some of which promote the growth of facial hair.
