I Have Gray, Thin Hair In One Spot Above My Right Ear — Could It Be From Cell Phone Usage?

Doc,
I have an area above my right ear where the hair is about 75% thinner — the hair itself, not the coverage, though that’s thinner too. There is also a substantial amount of grey hair here, but not the thick scraggly kind, these are also finer than the rest of my hair. Of note — I don’t have any grey hairs anywhere else but this area. No one in my family appears to have a similar condition. The only thing I can attribute it to is cell phone usage. I only hold the phone to my right ear, and while I don’t spend all day on the phone, I do take 20-30 calls/day. I’m interested in your comments.

Thanks

Some people have patches of different colored hair. This is also known as mosaicism, where different parts of the body have a different genetic make up. This can be normal and it is just the way you are. I do not know if this is related to cell phone usage, but I would think if it is from cell phone usage, you’d see many men and women walking around with patchy colored hair.
