I'll be 45 this month and in the last 3 years I've gone about 50% gray. Enough that I was asked if my youngest 4 kids were my grandkids! they're 13, 10, 8 and 5! So I now use henna on my hair to keep the gray at bay. Color dries my hair out and makes my scalp itch so much that I hate using it. I did color for years...I like being an almost red head! Henna takes a bit more time but is easier on my hair. I end up with soft manageable hair instead of the straw I was having! And since according to my 21 yo I'm YEARS away from grandkids Ive decided to not go gray just yet!
