Humidity: It's every curl's nightmare. That's because curly hair's unique structure exposes its cuticle. When humidity gets in, curls expand with unwanted volume and look frizzy, undefined, and dull.Ouidad's Advanced Climate Control Detangling Heat Spray primes curls to better resist frizz. Use it to seal every strand, fight tangles, and make curls more manageable. Ouidad's high-performance anti-frizz nano technology with a protein derived from silk seals the cuticle to form a barrier that locks in moisture and locks out humidity. Natural oils (grapeseed, sweet almond, macadamia nut, coconut, argan, and safflower) nourish and moisturize curls, while a dedicated UV filter helps protect against damage from heat styling and environmental aggressors.The result: defined, shiny, controlled curls-in any climate.
