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.

Best Overall: Design Essentials Natural Agave & Lavender Weightless Thermal Protectant Serum
When your goal is flowing hair that’s soft to the touch, the last thing you want is a greasy blowout weighed down by heavy creams and oils. Sanders says that she always applies this serum to her client's hair before flat ironing to give the hair a nice gloss. The lightweight formula seals moisture in the hair cuticle and adds an extra layer of protection from heat for a brilliant, silky finish.
Best Budget: Cantu Shea Butter Thermal Shield Heat Protectant
This budget-friendly heat protectant is a steal for those with thick, natural hair. It adds light hold to help your blowout withstand the elements, and pure shea butter hydrates curly and kinky strands while protecting it from temperatures up to 425 degrees Fahrenheit. The results? Hair that is sleek and hydrated.
Best Repairing Treatment: Olaplex No.7 Bonding Oil
Your hair goes through tons of stress over time from chemicals, heat styling, and even just brushing, but this all-natural oil is here to help undo some of the damage. It’s highly concentrated yet lightweight, and its star ingredient is Bis-aminopropyl Diglycol Dimaleate, which works by finding broken bonds and cross-linking them to rebuild them. Long story short: It’s nice to your hair when you aren’t, and it doesn’t just protect against heat damage, it repairs it.
