Weightless spray that protects all hair types
The best brand I’ve had to protect my hair from heat! It gives amazing texture and is easy to use. I have somewhat of thick hair and this is amazing for the texture. It takes me about 5 minutes to dry my hair and the scent is an added bonus! Leaves me hair smelling so good after blow drying!

An amazing heat protector
I got this a few weeks ago and overall I really enjoy it. I feel like it does a really good job as a heat protectant! I love how the bottle sprays as it is more of a mist than a jet. The one thing I am not the biggest fan of it I am not a fan of the scent. It’s not a bad smell but it’s just not my favorite but it’s still an amazing heat protectant and so the fragrance is nothing

Lightweight, residue free heat protection!
I love styling my hair using a hair blower or heating tool, but I find that it doesn’t take long before my hair starts looking limp and lifeless. This thermal shield spray by Nexxus prevents that by providing resilient heat protection up to 450 degrees! I also love that it doesn’t leave any greasy or annoying residue in my hair, meaning I can make it a consistent part of my haircare routine. Using it is easy, just follow the directions on the back of the bottle, work it into your ends, and wait a bit to let it settle in before heat treating. Overall, it’s a great addition to any haircare routine!

Good choice
This thermal shield spray prep and protect for 450 degree heat protection is really amazing, smells so good and the texture is very lightweight and the formulaitself doesexactly whatit promised. .

A few sprays beforeyour blow dryingyour hair or any heat processcan literallychangeyour end hair look and result. . The packaging design it perfect and I like how ot sprayed.

Loving it for my Curls!
I’ve been using this Nexxus spray on my hair, and I’m honestly impressed. My hair is naturally long, thick, and prone to frizz, but this helped smooth everything out without making it feel heavy or greasy. It gives my hair that soft, healthy look while still keeping the volume I love. What I really like is how lightweight it feels. I can spray it on damp or dry hair, and it instantly makes my hair easier to manage and look more polished. My hair feels hydrated, shiny, and way less tangled throughout the day. Definitely one of those products that quietly becomes part of your routine because it just works.

I don’t recommend
This product works but it’s nothing I would recommend. It’s a product I would use if I run out of my go to heat protector. It works temporarily for its claims but after awhile my hair was dry. Another reason this product wasn’t it for me is the spray pump. It went everywhere but the hair and would repeatedly stop working.

Softens, detangles, and protects from heat damage!
[This review was collected as part of a promotion.] Nexxus Prep & Protect Heat Defense Spray 6 oz review! I like that this stuff softens and detangles my hair while also protecting it from heat damage. I use a blow dryer every so often to dry my hair, but normally, opt for a cool setting so it doesn't damage my hair. However, this spary has helped in letting me blow dry my hair on warmer settings without the damage. I received this product for free from Topbox Marketing for testing and review purposes.

The best
[This review was collected as part of a promotion.] This is super great, I haven’t used a product like it. It’s not sticky or anything like other products. Cut down blow drying time and leaves my hair feeling soft. I received this product for free from Topbox Marketing for testing and review purposes.

It does it's job 🎯
This spray is great when it comes to preventing heat damage. Since I began to use the Nexxus prep and protect spray, I've had a noticeable decrease in frizz and split ends. The only thing I dislike is the build up. I feel a film of sorts after continuous use.

Excellent heat protectant
[This review was collected as part of a promotion.] I absolutely love the Nexxus Prep & Protect Heat Defense Spray. It has a wonderful scent that lasted in my hair, and I even received compliments on how good it smelled. After using it, my hair felt smooth, shiny, and well-protected when heat styling. It didn’t feel heavy or greasy at all. This will definitely become a staple in my hair routine and something I’ll continue to repurchase.

The best heat protectant with an amazing scent.
[This review was collected as part of a promotion.] I've been using this Nexxus heat protection spray for a week, and I loved the effect it had on my hair. It's super lightweight, doesn't weigh my hair down, and when I apply it, it leaves my hair with an irresistible feeling that makes me want to use even more. Girls, the packaging is beautiful, and I've become very attached to this spray; it has become my all-time favorite.I use it every time I need to dry my hair, which is practically every other day. I use it both at night and during the day. I apply it to my hair before using the hairdryer, and it leaves my hair simply wonderful, with a light and bouncy look. I loved it so much!I received this product for free from Topbox Marketing for testing and review purposes.

A Heat Protectant That Works on Brittle Hair
[This review was collected as part of a promotion.] Finding a heat protectant that doesn't weigh down fine hair is a big ask, but the Nexxus Prep & Protect Heat Defense Spray really impressed me. I have brittle, fine hair. I actually hadn't heat styled/blowdried in a year or so because I couldn't find a heat protectant that actually worked. I used this spray on my damp hair on my last wash day, and went for it with a blow dry and curling wand. It felt incredibly lightweight, not sticky or greasy, and it has a very pleasant, subtle scent that isn't overpowering. I was shocked at how healthy and bouncy my hair felt. Usually, my ends look fried after that much heat, but they stayed smooth and shiny. Other heat sprays have made my hair go limp after a few hours, but I'm on day 3 after my wash day and my hair is still full of volume, silky, and frizzfree! I would absolutely buy this spray again!

Love the scent
[This review was collected as part of a promotion.] I have mixed feelings about this product. As much as I like the fact that it’s lightweight and my hair feels soft and smooth after using it, I feel like it makes my hair greasy. The formula is more on the greasier side, and I thought that once it dries it will look normal, but i don’t really like that it makes my hair oily and greasy. Overall it does its job of adding shine and helping with the frizz control, but so far the greasy part is the downside for me.

Best hair product!

I usually apply it to damp hair in the morning, and I love how lightweight it feels—no heaviness or greasy residue at all. The spray distributes evenly and leaves my hair feeling soft and smooth. I also noticed my hair looks shinier and feels less dry after heat styling. The scent is clean and subtle, which I really enjoy. Overall, it does a great job protecting my hair while keeping it healthy-looking and manageable. I received this product for free from Topbox Marketing for testing and review purposes.
