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

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!

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.

Might go to spray it helps to detangler. It does not dry out your hair and it protects it from all of the heat styling products I use. It smells really good.

This spray is pretty good. I like the smell and it makes my hair feel super soft. I spray it in my hand then comb through my hair because the spray can be too concentrated for one spot. It doesn't spray out at a wide range. That's the only downfall but overall would recommend.

This lightweight spray shields hair from heat damage while leaving it smooth, shiny, and easy to style. Perfect for keeping your hair healthy and protected every day.
