One Celeb Hairstylist’s Secret Weapons

From deep conditioners to curling irons, find out what tools celebrity hairstylist Jennifer J. relies on to get red carpet-worthy hair

Kerastase Ciment Thermique

Blow dryers, straightening irons, and curling rods put our hair through major heat stress. That’s why using a product that will protect your hair is non-negotiable. “The Kerastase Ciment Thermique, $39, is my favorite heat-activated product,” says Jennifer J. “It conditions your hair as you use your hot tool,” she says. And while it is a cream, Jennifer J. loves it because it’s not heavy, so it won’t weigh your hair down.

“Since I’m a colorist, there are times that I dye and style my hair, not even caring that I’m risking damage. I just want the look,” she says. “But the Ciment Thermique restores my hair — no matter what I put it through — keeping it looking healthy and fabulous.”
