This hair chalk are awesome. That's all I can say. I have pink hair right now and I could notice the difference between my hair color and the chalk color. I try them all and I can't wait to do my entire hair and my nieces since there dressing as unicorns for Halloween. The chalk doesn't smell to good but it's temporary so it's worth it in my opinion and it will paint your hands a bit but it not anything you can't wash. In my opinion I love it. And plan to rock it. #RankBoosterReview #Sponsored #PinkyPetals
