Huang ZR, Lin YK, Fang JY. Biological and pharmacological activities of squalene and related compounds: potential uses in cosmetic dermatology. Molecules. 2009;14(1):540-554. Published 2009 Jan 23. doi:10.3390/molecules14010540 During our test, we were pleased by how smoothly it glided through the hair, making it easy to brush out. We also appreciated that after evenly distributing it through the hair, there was no smoke, sizzling, or other signs of burning when using hot tools. Despite being a cream formula, it felt incredibly lightweight and never made hair look greasy or weighed down, rather it added a noticeable shine and smoothness to styled hair. And if you like hair products that give your hair a light fragrance, this one contains the brand's iconic Côte d’Azur scent which lingers for a few hours.
Heat tools for hair — like straighteners, curling irons and hair dryers — are one of the biggest culprits of hair damage. Although there is no way to totally reverse the damage, you can minimize some negative effects by applying a thermal protecting leave-in styling product. In fact, two studies published in the Journal of Cosmetic Science ( 1998 and 2011) have shown that several ingredients (which include copolymers, hydrolyzed protein and cationic surfactants) can minimize hair breakage when applied before thermal exposure. Additionally, UV absorbers which boast similar benefits and work alongside vitamin E act as an iron curtain against heat damage, both man-made in our hot tools and nature’s UV rays. We also appreciate the inclusion of lavender and peppermint extracts that may help spur hair growth. We hope to see the fruits of that with continued use, but in the meantime, we’ll just be enjoying the calming herbal scent of a ritzy spa.If you’re using it on wet hair before you blow dry, Nai’vasha recommends applying it directly after towel drying the hair. “If it’s a spray, delicately and thoroughly mist from roots to ends, then, paddle brush throughout for even distribution,” she says. When using hot tools to style your hair, it is critical to have the best heat protectant spray on hand, no matter your hair type. “I’d highly recommend a heat protectant to anyone who uses a blow dryer or hot tools directly on their hair, to eliminate as much heat damage as possible,” explains celebrity hairstylist Alexander Armand, who sees clients from Marsai Martin to Serena Williams. We loved how well it absorbed into damp hair and worked to smooth fried ends, reduce frizz, and enhance shine. Though the brand recommends using a dime-size to a quarter size-amount, we recommend starting with just a dime-size amount and slowly adding more if needed—the formula is lightweight and residue-free in the hair, that is, unless you over-apply. All-in-all, we’re really impressed with this heat protectant, and we recommend it to anyone who prefers cream formulas and needs to tame frizz—regardless of your hair type.
What We Love: Damaged hair will thrive again—and this time, the antioxidant-rich ingredients in Olaplex’s patented bond-building system ensure it will be better protected from heat and environmental factors. Simply put, a heat protectant shields “your hair from heat, which may burn your hair, cause split ends, make your hair dry and lifeless,” says Iudina. Additionally, she adds, it can help your color-treated hair last longer. Without this safety net, hot tools strip your hair of its natural protein, making it weaker over time, disrupting natural curl patterns, and causing increased breakage.Oh JY, Park MA, Kim YC. Peppermint Oil Promotes Hair Growth without Toxic Signs. Toxicol Res. 2014;30(4):297-304. doi:10.5487/TR.2014.30.4.297 Our experts agree you should seek out oils, such as coconut and sweet almond, in a truly fantastic heat protectant as they coat the strands and “create a protective barrier when activated with heat,” says Johnson, who adds that since these oils are also super lightweight they won’t lead to wilted styles. Heat protectants are the SPF of haircare: Professionals tell us that you absolutely need to use one every day, or, in this case, every time you use a hot tool, to avoid causing irreparable damage. As celebrity stylist and curly hair aficionado, Nai’vasha Johnson says, “a heat protectant serves as our hair’s health insurance insurance.” Sure, it’s a little pricier than other protectants but we think it’s worth spending a little extra considering how, aside from a hairspray to hold our styles in place, we didn’t need to apply our usual finishing products, like rich oils and leave-ins.
Iudina also suggests looking for formulas with protein, like spirulina protein, which “works great for frizz control and smoothness,” she says. We’re fans of the Kérastase Résistance Ciment Thermique Blow Dry Primer in this regard because its formula has proteins and amino acids galore that strengthened our hair and boosted elasticity.
Chi is no stranger to making affordable products that actually work, and this gem of a primer gives the gift of a shiny halo all around our heads. This formula relies on the conditioning properties of hydrolyzed silk to bestow this angelic glow. It also makes the cream’s texture feel velvety and nourishing, likely the reason it’s been shown to help heal and restore protein to our strands from all the time we spend under foils coloring our hair.
