Dont like - wouldnt re buy. Hair just feels dirty again after use

The Nexxus Heat Defense Spray has quickly become a staple in my haircare routine. I use hot tools almost daily, and this spray gives me peace of mind knowing my hair is protected from damage. It creates a lightweight barrier that shields against heat without making my hair feel greasy or heavy. What I love most is how smooth and shiny my hair looks after using it. Whether I’m straightening, curling, or blow-drying, it helps reduce frizz and gives my hair a polished, healthy finish. The scent is light and pleasant—not overpowering like some other sprays I've tried. A little goes a long way, and the spray nozzle gives a nice, even mist that distributes perfectly. Since I started using it, I’ve noticed way less breakage and dryness, even with frequent styling. If you're looking for a reliable, salon-quality heat protectant, Nexxus really nailed it with this one. I highly recommend it for anyone who wants to keep their hair strong, soft, and protected while still using heat tools.

If you’re looking for a lightweight, high-performance heat protectant, the Nexxus Heat Defense Spray Prep & Protect is an absolute game-changer. I use it every time I blow-dry and straighten my I-tip extensions, and the results have been flawless—no split ends, no dryness, just soft, healthy, and silky-smooth hair. This spray protects against heat up to 450°F (although I've only tested to 375°F), making it perfect for anyone who regularly styles their hair with high heat tools like flat irons, curling wands, and blow dryers. I’ve been using it in combination with Nexxus Hair Oil, and my extensions still look brand new—no signs of heat damage, breakage, or frizz. Unlike many heat protectants that weigh hair down or leave behind a sticky residue, this spray is feather-light and completely weightless. My 22-inch extensions still move naturally, with no buildup or greasiness. It gives my hair a soft, bouncy feel while keeping it protected from daily styling. If you love a good luxurious scent, you will adore this spray! It has a salon-quality fragrance that lingers lightly without being overpowering. Every time I use it, my hair smells fresh, clean, and elegant—like I just stepped out of a professional blowout. One of my favorite things about this product is how smooth and sleek my hair looks after styling. It boosts shine, tames flyaways, and gives my extensions a polished, healthy glow. Whether I use a round brush for a voluminous blowout or a flat iron for a sleek, straight finish, my hair looks silky and frizz-free every single time. Extensions require extra care to maintain their health and longevity, and this product delivers next-level protection. It helps prevent split ends, keeps hair from drying out, and maintains softness even with frequent styling. Whether you have extensions or natural hair, this is a must-have for anyone who heat styles regularly. The Nexxus Heat Defense Spray Prep & Protect is hands down the best heat protectant I’ve used for my extensions. It provides salon-level protection, enhances shine and softness, smells amazing, and leaves my hair feeling weightless and smooth. If you want to keep your extensions healthy and damage-free, this is the ultimate must-have!

Been using this spray for a month now to flat iron my hair. Works really well. My hair is bleached and colored (black and blonde) and long and it’s done well! Smells good, too and it mists well on the hair instead of getting sticky or anything similar.

Light, not sticky and leaves hair soft and tangle free. Love this product

use this Nexxus heat defense spray before blow drying or using hot tools and it works well. It sprays evenly and doesn’t leave my hair feeling sticky or crunchy, which is always my biggest concern with heat protectants. What I like: • Lightweight and easy to spray • Doesn’t weigh hair down • Leaves hair feeling smooth, not greasy • Works well as a prep step before styling What to know: • A little goes a long way. Too much can make hair feel coated • The scent is noticeable, though not unpleasant Overall, it’s a solid heat protectant that does what it’s supposed to do, and I’ll keep using it.
