Men taking Propecia run the risk of sexual side effects, but most experts say that it only affects a small minority. The risks are greater for women, especially those who are pregnant or may become pregnant. Experts warn that so much as handling the tablets can lead to serious birth defects. Like minoxidil, Propecia use must be continued for as long as results are desired.

Laser treatments are the latest frontier in staving off hair loss, and they’ll be the first choice for fans of sci-fi. As silly as they may sound, these treatments do work — the American Journal of Clinical Dermatology in 2014 reported a “statistically significant difference” in hair density with no “serious adverse events” or side effects.The bad news: Laser treatments tend to be expensive, progress is slow, and they don’t always produce stellar results.


In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
