I'm 39 and I tried growing my hair out last year. I started graying at 25 and I'm about 60% gray now, I guess but this did NOT go over well. My mom's friends told her they thought it made me look old! (My DH wisely didn't say a word! ;-) Also, I have light skin and I think all gray can look stunning on a darker skinned person but it just washed me out so I'm back to brown!
