my Father was completely gray in his 30's but mine didn't come in completely till my 40's I think. I used to have my hair highlighted, then became more gray showing, so i had it "low" lighted (several colors added). Houston has great hair dressers.
i let it grow out after moving to Colorado.My son is 42 and has lots of gray now but keeps his hair so short you can hardly see much of it.

You look great to me. :thumbup:
