Review (4/5): Fun, but don't trust the manufacturer's photos
Your hair will never look as vibrant as the seller's photos. Just accept that. Those were definitely NOT done with hair chalk.
That being said, these are still tons of fun to use, and I've enjoyed painting my husband's silver hair in rainbow colors. :) Check out the images that reviewers have posted to get an idea of how they really look in both dark and light hair.
The chalk will make your hair feel a little gummy, and the colors will rub off on pillows, etc., but it washes out easily.
