I have tried just about everything that has been mentioned - I have had graying hair since I was 16! My favorite is Nutrisse by Garnier - it has the best smell, it lasts for me, and isn't hard on my hair. I used to get it done at the salon, but since I've had my kids its too hard to go to the salon for 3 hours to get my hair done. (Not to mention the cost, which I can't seem to get past now that I have kids!)So now my DH does it for me once the kiddies are off to bed, and in about an hour 15 minutes, I'm done! Nutrisse has recently added highlighting kits to their line, and I'm intrigued to try them.
HTH,
Tricia
