Must-Have for Heat Styling!
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.

Attention Extension Girlies!
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!

Fantastic
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.

Good Product!
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.

Works great
This is one of the best heat protecting that I ever used. If you buy it, you might want to buy more than one. It even has a nice scent to it

Not worth
**Product Review: Hair Heat Defense Spray** Rating: ★★★☆☆ (3/5) I’ve been using this heat defense spray for a few weeks now, and while it does the job, it didn’t quite live up to my expectations. The spray itself has a pleasant scent and doesn’t leave my hair feeling heavy or greasy, which I appreciate. It also provides some protection against heat styling tools like flat irons and curling wands, but I didn’t notice a significant difference in how smooth or shiny my hair looks after using it. One of the issues I’ve had is that my hair still seems to get a little frizzy after styling, and it doesn’t feel as soft as it does with other heat protection products I’ve tried. I also wish it offered more lasting protection, as I’ve had to touch up my hair more often than I would like. Overall, it’s an okay product for the price, but it doesn’t stand out in terms of performance. I’ll finish the bottle, but I’ll likely be looking for something with better heat protection and smoother results next time.

The shine it gives is incredible, and it smells amazing too. I can really tell it’s protecting my hair — no more dryness or frizz! This spray is a total must-have for anyone who styles their hair often.

Works great on my hair but I can’t get over the smell, it is like a horrible grandma perfume.

Repeat purchase - aerosol heat sprays fry my hair. This is not alcohol based it is more like a leave in conditioner. No grease or wet look. Has saved my hair from being fried with my styling wand and straightener. Works well in extensions also. Great for heat styling with blow dryer and brush.

Horrible product. Washed my hair then put this on before blow drying to protect from the heat, my hair became incredibly oily and heavy, after finishing the blow dry, it looked like I didn't wash my hair at all, that's how oily my hair was. Really regret spending money on this.
