HAIR LOSS IN MEN

The cause of hair loss in men is almost always genetic. It occurs in men between the ages of 18- 65 years of age. It follows a specific pattern, which may vary, greatly from one man to another. This pattern is called male pattern baldness or androgenetic allopecia. Men experience hair loss because their hairs are genetically susceptible to the hormone called DHT or dihydro testosterone. DHT will attack susceptible follicles and cause them to slowly shrink and eventually die.

Male-pattern baldness is so called because it tends to follow a set pattern. The first stage is usually a receding hairline, followed by thinning of the hair on the crown and temples.

When these two areas meet in the middle, it leaves a horseshoe shape of hair around the back and sides of the head. Eventually, some men go completely bald.Treatments can slow down the process, but there’s no cure. The two most effective treatments for male-pattern baldness (also called androgenetic alopecia) are minoxidil and finasteride, but in varying degrees.

NORWOOD SCALE ( Stages of Hair Loss)

Most hair replacement surgeons refer to hair loss in stages as defined by the Norwood classification published in 1975 by O’Tar Norwood.

Most hair loss follows a predictable pattern although variations occur frequently. The stages of hair loss displayed are useful in determining baldness in most men. The following charts have been helpful for doctors and patients in determining the extent of the hair loss in males.
