I highly recommend it for anyone who wants to keep their hair strong, soft, and protected while still using heat tools.

This is my go-to heat protecting spray from here on out. It smells good, it works good, and I feel the price is fair. I know Nexus is a good brand, so far this is the only Nexus product I've used and I love it. My hair is growing out from menopause hair loss and I'm trying to keep it healthy. I also bleach my hair, so it's very delicate. This stuff works well. The picture show some breakage for sure, but you can tell the new growth is healthier and will eventually catch up with the rest of my hair.

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!

Eh. It’s your average leave in conditioner type heat protectant. I bought this hoping I could spray it on my ends and my roots (like the instructions say to do). But I find that if I spray it I my roots, it weighs my hair down and makes it greasier faster. Works fine on my ends, average detangling power and makes my blowouts look smoother.

I can't believe how well this works! I was late to the party of using a heat protector, because I basically use my blow dryer for 3-4 minutes at the most, maybe twice a week, and no other styling tools; but this is great in taking out any tangles and also leaves my hair in great condition.

I absolutely love this product. Only thing is with the shipping it is trickle because sometimes it arrives spilled/damaged. I have found buying it locally at Target is better. It provides great protection. Hair is so soft.

I LOVE LOVE LOVE this prep and protect spray. It is one of the best smelling products I have ever used, and last a long time! A little goes a long way. Would deff recommend!

**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.
