A person’s hair growth normally lasts for 2 to 6 years, with each hair growing an average of ½ inch per month. It is estimated that about 90 percent of the person’s hair on the scalp is growing while the remaining 10 percent is resting. The resting hair starts to fall out after two to three months, and in the normal process, new hair will take the place of those that have fallen out. Alopecia or hair loss occurs when new hair fails to replace those that have fallen out.
