It can be long and wavy, short and straight, frizzy and unmanageable, or smooth and shiny. Hair comes in many different lengths, styles, colors, and textures. Yet just about everyone — no matter what kind of hair they have — falls prey to at least one hair problem at some point in life.This article covers some of the most common hair dilemmas, from hair loss to greasy hair.
Some people consider gray hair as something that makes them look distinguished; for others, it’s a reminder that they’re getting older. How ever you feel about it, gray or white hair is pretty much inevitable with age (if you’re fortunate enough to still have hair in your later years).
Scientists have put a lot of effort into investigating the cause of gray hair, and they believe they’ve gotten to the root of the problem. Hair gets its color from a pigment called melanin,
which is produced by melanocyte cells in the hair follicles. Researchers have discovered that melanocytes endure cumulative damage over the years, which eventually leaves them unable to produce melanin.
Studies have cited DNA damage and a buildup of hydrogen peroxide in the follicles as possible causes of this disruption in melanin production. Without melanin, the new hair that grows in has no pigment, which makes it appear gray, white, or silver.
