MALE PATTERN BALDNESS
Baldness
Androgenic alopecia is the most common type of progressive hair loss. It is also commonly referred to as male-pattern baldness or female-pattern baldness.
Male Pattern Baldness
Affecting around 50% of all men over the age of 50. It usually starts around the late twenties or early thirties and most men have some degree of hair loss by their late thirties.
The pattern of the hair loss commonly begins as a receding hairline, followed by thinning of the hair on the crown and temples, which leaves a horseshoe shape around the back and sides of the head. The degree of Male Pattern Baldness (MPB) can be measured using the Norwood Hamilton Scale. These range from a Norwood 1 (NW1) where no hair loss is experienced, through to Norwood 7 (NW7) which means a total loss of all hair on top of the head, with or without the ‘horseshoe’ ring of hair at the back and sides.
Female Pattern Baldness
In women the age of onset is usually later, occurring around the age of 50. Up to two-thirds of women experience hair loss after menopause. The pattern in which women lose their hair is different to the pattern for men. Women lose hair from all over their head, starting at the parting and hair at the temples may also recede.
