Hair often shows it age by going gray or white.
It may also be thinning, thickening, or falling out. In women, as the hormonal balance between female estrogens and male androgens shifts, hair on the head may thin while body hair may start to grow darker or thicker. Men may find that their body hair becomes thinner in tandem with the hair on their heads. Then again, some people in their 60s find that hair on their head grows curlier and even darker in color.
