Attention Extension Girlies!
If youâre 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 flawlessâno 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. Iâve been using it in combination with Nexxus Hair Oil, and my extensions still look brand newâno 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 elegantâlike 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 Iâve 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!

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 Iâm straightening, curling, or blow-drying, it helps reduce frizz and gives my hair a polished, healthy finish. The scent is light and pleasantânot 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, Iâve 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.

Protecting my thinning hair
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.

Good heat protectant
Smells nice, non sticky, non greasy and protective.

High quality heat protection
Amazing smell for heat protectant. My hair is very thick and I use heat on it often and I have noticed that I do not have split ends with the amount of heat that I use on my hair. The bottle is big and a little bit of product goes a long way, so it is worth your money

A Must-Have for Protecting Hair from Heat Damage!
Iâve been using the Nexxus Heat Defense Spray for a few weeks now, and Iâm really impressed with how well it works. It provides excellent protection against heat damage, whether Iâm using a blow dryer, flat iron, or curling iron. The spray goes on light and doesnât leave my hair feeling greasy or weighed down. It also adds a nice shine and keeps my hair feeling soft and smooth all day. I love that it protects without compromising the style, and my hair feels healthier even after frequent styling. Definitely a staple in my hair care routine!

Not worth
**Product Review: Hair Heat Defense Spray**Rating: â â â ââ (3/5)Iâve been using this heat defense spray for a few weeks now, and while it does the job, it didnât quite live up to my expectations. The spray itself has a pleasant scent and doesnât 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 didnât notice a significant difference in how smooth or shiny my hair looks after using it.One of the issues Iâve had is that my hair still seems to get a little frizzy after styling, and it doesnât feel as soft as it does with other heat protection products Iâve tried. I also wish it offered more lasting protection, as Iâve had to touch up my hair more often than I would like.Overall, itâs an okay product for the price, but it doesnât stand out in terms of performance. Iâll finish the bottle, but Iâll likely be looking for something with better heat protection and smoother results next time.

Great product. Careful with shipping.
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.

Great Smell! Protects against heat damage.

Use strictly when round brushing my curly hair to straight. Iâve found that I get a sleeker blower out with less frizz

A lot of heat protectors leave a film on my hair and usually I’d have to wash my hair at the end of the day after styling with it. This one was much lighter but still slightly weighs down the hair. Would still purchase this again though
Heather S. –
This product smells TERRIBLE!! It is a VERY strong floral scent. Like a grandma. I don’t even know how it performs because I can’t stand it long enough. Would have been nice to know the scent was so floral, as I would not have bought it. Returning it immediately! Bleh.
