Why Some People's Hair Turns Gray

We asked a dermatologist to explain why hair turns gray, and why it happens to some people as early as their 20's. According to Dr. Jennifer Chwalek, genetics will likely determine whether or not you will go gray, and how soon it will happen.

I’m getting gray hair and I’m 16, it’s freaking over for me ;(

My aunt went grey at 20. Even as a kid I thought it was so cool and look for grey hairs to see if mine would do that. I think it's amazing. I'm 21 now and still no greys, but when they come, and they will, I'll greet them as old lil friends.

Many young people are going gray nawadays

The difference is, when you are FULLY grey. It's kinda hot. When you're part and part, it makes you look older

At least he's not balding. It's better to get gray hair early than to bald early.

Why didn't his beard and mustache hair go grey?

[billiesearlobe]

Lmaooo I read this like “ Why some peoples’ hair turns gay”.... that was a moment

My boyfriend is 21 and he’s been going grey since he was 16 too. At this point his hair is still mostly black but has grey hairs everywhere mixed with the black. I think it’s beautiful and unique and I love how it looks on him 😍 his dad is 45 and is only grey in the front of his beard and nowhere else and his great uncle went grey at 16 like my boyfriend. I wonder how the gene will pass down to his children.

It took my Dad until the age of 70 even begin going grey. Pretty odd!

why is Joe greying prematurely?

Doc: "when individuals grey before the age of 20, it's called premature greying".
