i have a little patch at the front right side of my hair at the hairline. It grows pure white hair. I only noticed it about a month ago when i stopped bleaching my hair & dyed it black. The regrowth in that area was white & i just figured it must be the constant stress on the hair from 8 years worth of bleaching every 3 weeks. WHITE HAIR GROWTH IS NOT RESTRICTED TO AGE FACTORS!!!! (for all those people who wrote "age ...duh") i'm 31!!

Hair and skin pigmentation is caused by a specialized cell in the skin called a melanocyte. This cell creates the pigment melanin, which is what we see as color. It injects the hair follicle with this pigment, which is why we see color in the hair. Genetics will usually determine when the melanocytes stop producing color, and each area of melanocytes is different. (This is why you will always have pigment in your eyes or skin, even when your hair turns white). Trauma can lead to the premature death of melancocytes, which is why scars are white spots that won't tan on your skin. This can also happen with hairs, although it isn't as common.

Age...
But my 25 year old roomate has a white patch on his head from a girl in high school that used to pluck his hair out, and when it would grow back, it would grow back a little bit lighter, and she'd pluck it again... this kept up untill that spot of hair started growing out white.... but other than that... age.

Eventually the pigment in the hair folicle wears away, causing the colour to diappear. Like colour from a printer. colour runs out everything is in black andwhite
