Hair Loss in Men (Androgenetic Alopecia)
Some men never go "bald" but everyone's hair thins out over the years. The term androgenetic refers to the fact that common balding requires both male hormones (androgens) and a genetic tendency to lose hair. Because there are many genes involved, however, you can't look at your parents and know how much hair you will lose or how fast you will lose it. In particular, the idea that hair loss is passed down from the mother's side of the family is folklore, not fact.
The problem of hair loss has resulted in many other myths and misconceptions. For instance, wearing hats does not "choke off" hair roots and promote baldness. Likewise, longer hair does not put a strain on roots.
Once you think your hair is thinning, it's worth a check to be sure. Even men who never lose much hair develop some receding at both temples during adolescence. Boys' hairlines are straight across; adult men have more of an M shape.
Many conditioners, shampoos, vitamins, and other products, as well as procedures involving lasers and heat, claim to help hair grow in unspecified ways. These are harmless but useless and not worth the investment. To slow down hair loss, there are just two medically proven options:
Stopping either Rogaine or Propecia puts you back where your hair loss would have been without them, but not worse off.
Besides these medical treatments, there are various ways to camouflage hair that has already gone. These include hairpieces or hair-weaving processes. Toupees require tape or other ways to keep them from sliding off, and they also stretch and oxidize. Hair weaves loosen and need periodic restyling.
Techniques for performing surgical procedures like scalp reduction and hair transplants have improved over the years, producing better, more natural results. Transplant surgeons do their best to use hair that is not genetically programmed to fall out later. Taking Propecia after a transplant also helps to retain hair.
Shaving the scalp has been fashionable and is an option other than trying to grow more hair.
