Product Information

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. What We Love: This formula only consists of nourishing ingredients that feel weightless on our strands, but it still includes everything to protect them from damage. Take, for example, its inclusion of ceramides, a lipid that helps hair retain moisture by acting as a laminator between your strands and anything that can cause brittleness, like the heat from our hot tools. Split ends? Those are left in the past along with dullness, static, and breakage. We’ve turned dpHue before when we wanted to keep our blonde hues bright and strands glossy in-between visits. Similar to those two color-centric formulas, this protective spray is free of gloss-stripping additives, like sulfates. Instead, the base of the formula is tocopherol, also known as vitamin E, to gently hydrate our hair and supply it with the nutrients it needs to be strong and healthy. And, in turn, our color-treated hair lasts longer and looks richer.

What We Love: The formula leaves out sulfates, silicones, and other potentially harmful ingredients that could strip color and lead to dullness.

What We Don’t Love: It leaves behind a light residue that lasts until you blow dry or brush out your hair

Jin M, Chen YL, He X, Hou Y, Chan Z, Zeng R. Amelioration of Androgenetic Alopecia by Algal Oligosaccharides Prepared by Deep-Sea Bacterium Biodegradation. Front Microbiol. 2020;11:567060. Published 2020 Sep 29. doi:10.3389/fmicb.2020.567060 It’s a fine line for us curlies to walk: We need all the hydration help we can get, but without causing our spirals to become heavy and fall flat. Yet, this Mizani spray protectant shows that small and simple can most certainly be mighty. With a lightweight mix of conditioning ingredients, such as tea tree oil and propylene glycol, we got better-defined bouncier coils, ringlets, and waves.No one is safe from split ends, but one look at our brittle texture and fried ends reveal that we haven’t always been the most diligent with keeping our hair hydrated. And to be honest, we weren’t expecting a miracle, given the messy, vulnerable state our hair was in, but somehow, Olaplex managed to repair and strengthen our strands.

We think of the primer a little like the same kind you apply before makeup: It prepped the hair before we styled it and helped better hold our styles—our hair even looked soft and bouncy after an intense gym session.

Of course, the number one rule is always to use it before applying any kind of heat – that means blow drying, hot rollers, flat irons, and curling wands. Whether you’re using a cream or a spray, the key to applying any heat protectant is ensuring it's distributed throughout the hair. Just like with sunscreen, if you miss a spot it’s prone to the adverse effects of heat. 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. Seriously, our hair looked healthier after just a few uses, and gave us so much shine, likely due to the addition of rose water. This super hydrator often flies under the radar, but it’s brimming with vitamins and antioxidants to soothe the scalp and protect our color-treated hair. With the addition of salicylic acid, a natural surfactant, the formula naturally mitigates oil production.
