When you’ve worked long and hard to get your natural hair to its healthiest, bounciest state, you don’t want to forfeit your curl pattern to damage caused by temporary straightening. With the right products, you can have the best of both worlds and go in and out of curly and straight styles with little to no curl casualties. The best heat protectants will help your curls bounce right back while giving you the sleek, frizz-free look that you desire. Of course, no one can give you a blowout quite like a hairdresser, so we went straight to the source for advice on heat styling your tresses without the damage.
Stylist Lyonisha Sanders of Lavish Salon & Extension Bar specializes in healthy hair, whether natural, relaxed, or color-treated. “Hair is just like a plant," she says. "You must nurture it and apply all the nutrients it needs so that it can blossom, grow, and maintain its integrity. When styling with heat, I always apply all of the nutrients while hair is wet, so that the hair can absorb them better."
Most heat protectants don’t guarantee results over 450 degrees Fahrenheit, so even if your styling tool can get hotter, go easy on the heat. Staying below this temperature will ensure that your strands aren’t getting damaged on your quest to silky smooth hair.
