“If you have curly hair, this treatment will soften and loosen your curls, but it won't change your curl pattern to make your texture pin-straight,” she says. “If you have straight, frizzy hair, this will eliminate the frizz making it easier and faster to do your hair at home. If you make it routine, you will find your hair becomes stronger and healthier over time, improving from the inside out,” explains Dana Tizzio at Butterfly Studio Salon.
The Cezanne treatment is formaldehyde-free and employs a different active ingredient: sericin, produced by a silkworm. “It wraps around each hair strand to smooth it, which is what makes this a game-changer,” says Tizzio. Other treatments lay flat on the hair strand. Tizzio notes that the ingredients get locked into the inner hair shaft and allow it to become more healthy and easier to style overall. “Not having to put so much heat on your hair is a lot healthier on your strands, too," she adds. "In the long run, combined with your other better habits (like using the right hair care), it will be so much better for the strength, look, and feel of your hair, if smoother is what you're going for.”
