What Causes Hair Loss?
We all lose around 100 hairs a day, but there are 50 disorders that can cause hair loss, each with different symptoms and causes, but Male Pattern Baldness (MPB, also known as Androgenic Alopecia) is the most common one. MPB gets its name because it causes a set pattern of a receding hairline followed by thinning of the hair on the crown and temples. As a result, Male Pattern Baldness leaves a horseshoe shape of hair around the back and sides of the head. In general, it usually starts around the late 20s or early 30s and by the late 30s, most men have some degree of hair loss. It is estimated that 6.5 million British men are affected by Male Pattern Baldness.
The age of onset, extent, and rate of hair loss vary from person to person. Severe illness, malnutrition, or vitamin deficiency can accelerate this process. When applied incorrectly, permanent hair colour and chemical relaxers damage the hair and follicle to the extent that hair loss can be permanent.Causes of hair lossdo not includewearing a hat, excessive shampooing, lack of blood flow, or clogged pores.
Hamilton, and later Norwood, have classified the patterns of male pattern baldness. Although the density of hair tends to lessen with age, we cannot really predict the pattern. In general, young men who begin losing hair in their 20s will experience the most severe baldness.
Unlike male hair loss,female hair lossmay commonly begin at any age through 50 or later, may not have any obvious hereditary association, and may not occur in a recognizable Female Pattern Baldness of diffuse thinning over the top of the scalp. Women tend to have less obvious patterns of hair loss than men which may be due toconditions other than Female Pattern Baldness. Some of the most common of these causes are trichotillomania, alopecia areata, triangular alopecia, telogen effluvium, and scarring alopecia, which can be caused by, for example, lupus erythematosus, scleroderma, and infectious agents.
