This stuff is AMAZING!
[This review was collected as part of a promotion.] So l've had this now for a few weeks, as I wanted to really try it and see how it worked with my hair. I have to tell you you that this heat protection spray is amazing. It makes my hair very soft, manageable, looks healthy and easy to style. I have tried many heat protection sprays and they all leave my hair dry and crunchy. Not this one, this one is by far THE BEST I've ever used. Will I but it again, maybe. It is a bit pricey but they say you get what you pay for and who doesn't want their hair looking the best?
Thank you BuzzAgent for allowing me the time to really use this heat protection spray. I highly recommend it, it is THE BEST heat protection spray I have ever used!!

Good Heat Protecting Spray
[This review was collected as part of a promotion.] I love the smell and the fact that you can spray it and that it doesn't turn crunchy or hard. My hair is very thin and fragile, and I like that it makes it soft. I believe that my hair feels smoother and more protected from heating tools. My only reservation is that the liquid is a bit thick for the way the spray nozzle projects it so it sprays out a little bit unevenly. I think perhaps a different spraying nozzle would help in distributing the product a bit more evenly. What I sometimes do is spray it in my hand and then rub it through the length of my hair.

Seals ends instantly and protects from heat
I spray a few pumps of the Defense Thermique spray on my hands and spread through my towel dried hair before blow drying to protect my fine, thin color treated hair from heat damage. Once dry, will spritz a tiny amount on any dry or split ends and it immediately smooths them out without making my hair greasy or sticky (key is to use sparingly and a little goes a long way)

Perfect for summer
I bought this product to go along with the shampoo & conditioner of the same line. I like the feel of it in my hair after sitting by the pool for hours in the sun. My only qualm about it is, i don’t like the applicator. I usually spray it into my hands & distribute it through my hair instead of spraying it on directly.

It is alright…
[This review was collected as part of a promotion.] I used it a couple times and it's alright. It smells nice, like a perfume/cologne and leaves hair soft and fluffy. I haven't noticed any heat damage so it appears to do its heat protecting job. When used on its own it doesn't leave hair sleek after blow drying like other heat protectors which is more of what i am used to and looking for.

Great heat protectant!
[This review was collected as part of a promotion.] This product does a great job at being a heat protectant, but also leaves my hair more silky and shiny. The only thing I'd improve is the scent. It has a pleasant citrusy top note, but then the there is another scent that lingers that I don't really care for. Otherwise it's an excellent product that I'd recommend!

I've never really been able to blow dry my hair because it would always end up all over my head and so dry and frizzy but this stuff is like a miracle in a bottle a must have. it's really something to good to be able to explain all of the goodness!

Love My Hair with Defense Thermique Blow Dry Primer
[This review was collected as part of a promotion.] I've been using the Defense Thermique Blow Dry Primer and it's a total game-changer for my hair routine. The heat protection is fantastic – no more damage from my styling tools. My hair feels healthier, looks shinier, and the ends are much smoother.
It's super easy to use, lightweight, and doesn't leave any residue. Plus, it smells amazing! My hair dries faster, is more manageable, and has a gorgeous shine. Highly recommend it for anyone using heat styling tools. It's not just a heat protectant; it's a complete hair care treatment!

[This review was collected as part of a promotion.] This product was great! After blow drying and straightening my hair I could feel it working against the heat. I had no frizz and hair seemed shinier. The only thing I disliked was it made my hair feel weighed down. I have semi-thin hair and straight with some wave and a naturally oily scalp. Hope that helps anyone looking to purchase this product!

Perfect product for winter hair relief!
[This review was collected as part of a promotion.] My hair tends to get extremely dry and brittle, especially in the winter months, and I tend to dry and style it almost every day so I need quality products to keep my hair healthy. I'm pretty picky about my hair products because I have fine hair that easily absorbs too much product and quickly becomes greasy and heavy from product overuse but I found the Kerastase hair primer extremely lightweight and easy to apply. I felt like it protected my hair very well against the heat tools, but it also gave my hair a beautiful shine and smoothness even when used alone. It's a great, high quality product that delivers what it promises.

Leaves my long hair soft and easy to brush
[This review was collected as part of a promotion.] I received this Heat Protecting Leave-In Treatment free for an honest review from BzzAgent- and I absolutely love this product! I have long hair to my lower back so it's a lot to brush through. I spray this on it while still wet and it makes it sooo much easier to brush through. It leave my hair smelling nice and I feel better about it when I use the blow dryer and curling wand. Throughout the day, my hair feels soft and holds it's style. A little goes a long way so I think the bottle will last a while. I've used it for the last month and still have more in the bottle and I use it most days.

Works great!
[This review was collected as part of a promotion.] This product has been a secret weapon! I love that it's a spray so I don't have to get my fingers messy before I blow dry. I use it towards the middle & bottom of my hair, and it makes it look great. The smell is clean and pleasant, and it makes my hair feel nourished, smooth, and protected. It is a bit pricey, but if it makes my hair look like I've just had a blow out, it may be worth it. I've been looking for a new hair lotion, and I think I may have just found it!

[This review was collected as part of a promotion.] Great product. I use this regularly on damp hair and it seems to help detangle my hair and keeps it smoother than when I didn't use product while blow drying. An added bonus is that it smells good and is in a pump bottle, not a spray nozzle.

A Game Changer for Heat-Styling Enthusiasts
[This review was collected as part of a promotion.] As a recipient of the Defense Thermique Blow Dry Primer for trial purposes, I am writing this review to share my experience with it. Having tried various hair care products over the years, I found this primer to be quite unique in its effectiveness. Compared to other products, the Defense Thermique Blow Dry Primer stands out for its ability to protect hair from heat damage while also enhancing hair's natural shine and smoothness.
One of the key benefits of owning this product is its dual-action formula that not only shields hair from the high temperatures of styling tools but also nourishes and conditions the hair. This leads to healthier-looking hair even after frequent styling. Another notable advantage is the lightweight texture of the primer, which does not weigh down hair or leave any residue, making it suitable for all hair types.
Personally, I would definitely consider purchasing this product in the future. Its protective qualities coupled with its nourishing benefits make it a valuable addition to my hair care routine. I would highly recommend the Defense Thermique Blow Dry Primer to friends and family, especially those who regularly use heat styling tools.
Please note that I received this product complimentary for testing purposes, which has allowed me to provide this honest and unbiased review.

Detangles and fights frizz
[This review was collected as part of a promotion.] I really like how this Blow Dry Primer makes my hair look and feel. After washing and towel drying my hair, I spritz my hair 4-6 times with Defense Thermique Blow Dry Primer. I usually smooth it throughout my hair with my hands first, then I brush the Primer through. I found that I don't need a detangling spray with this product, which is great since my hair is long and gets knotted up very easily. After blow drying, my hair truly is so smooth that I rarely have to use a flat iron. It also has a nice, clean scent that lasts. The only downfall is that it's a little pricey and you can blow through a bottle pretty fast.

[This review was collected as part of a promotion.] I love this blow out spray. It leaves my highlighted blonde hair looking healthy and smooth, all while feeling silky and not weighed down. This product also smells amazing.

Really loved this!
[This review was collected as part of a promotion.] I have fine thin hair but a lot of it. I tend to get greasy hair from to much products in my hair. So I sprayed this straight into my hands then worked it into my ends, instead of spraying on the hair. This worked perfectly. My hair had body, shine and was very smooth. I wish it was not as perfume scented but it was not enough that I would not buy it again. I would really recommend it.

I have fallen in love with this formula
[This review was collected as part of a promotion.] I have some heat damage to my hair and had almost given up on products. I literally love the way my hair feels and smells from Defense Thermique blow dry primer. I promise if you try it you will love it. My hair is soft, manageable and smells amazing!!

Does what it says it will do - moisturizing but not heavy
[This review was collected as part of a promotion.] I have very long, fine to medium fine, straight hair. I like keeping my hair straight but sometimes I make it wavy - it is so straight that it is hard to shape it really. I apply this on wet hair after shower and before blow drying. Obviously any product will weigh the hair down and I use this sparingly on the bottom half of my hair - not on top, never on the scalp as any product on scalp will make my hair flat and instantly greasy. Once on bottom half I do spread it around while blow drying and the shine this imparts is insanely gorgeous! It protects my hair from heat and has actually improved the texture overall! Tip: I sometimes apply it without blow drying just on the tips to make my hair less frizzy/electrostatic and also nourish them. It is a leave in treatment for your hair afterall so I try to be innovative with using it.

New Favorite
[This review was collected as part of a promotion.] This is my first time using Kerastase and I have to say, I'm quite impressed! This light weight formula helps smooth and protect your hair from heat damage. The scent isn't over powering and fades away after it dries. A little goes a long way, which is great given the price! I color my hair a lot and need anything I can to help strengthen my hair. Definitely recommended giving this a try if you need a good leave in treatment.

New staple in my routine!
[This review was collected as part of a promotion.] I was gifted the Kerastase Paris Defense Thermique Blow Dry Primer in exchange for my review!
I love the smell of this product, i've been using it every wash for 2 weeks now.
The smell is great and not over powering it also seems to last a while!
My hair is virtually FRIZZ-free which is absolutely amazing! it's hard to tame my hair. My hair is super silky and smooth. I also feel great using this product knowing i'm protected. I love how this product does not create a residue or feeling in the hair! I would highly recommend, this is a new staple in my routine for many reasons!

Time will tell
[This review was collected as part of a promotion.] I only wash my hair every other day and adding this product to my routine didn't weigh the hair down or make it need washing sooner, which is a significant plus. My hair felt smooth and soft while drying, without pulling or breaking. The true test will be as time passes but so far the results are great!

High Quality Treatment
[This review was collected as part of a promotion.] This product has helped my hair feel stronger and more shiny. It also has reduced frizz for my straight hair. The scent is a little stronger than I would prefer, but it's not overpowering. I received a free sample of this product, but I would purchase next time I am shopping for a leave-in treatment.

Love it! Highly Recommend!
[This review was collected as part of a promotion.] I received the Kerastase Paris Defense Thermique Blow Dry Primer to try in exchange for a review and let me tell you, it's a total game-changer. This stuff easily scores a solid 5 stars in my book.
First off, the smell is amazing – it's a fancy fragrance that hangs around all day. Putting it on is easy thanks to its lightweight feel, and it spreads through my hair like a dream before I blow dry it. And the heat protection is wonderful. My hair's basically invincible to the styling tools now, and I've noticed way less split ends and breakage.
But that's not all – this primer leaves my hair feeling crazy soft and easy to manage. It's like a magic detangler, making styling way less of a hassle. My hair's looking way healthier, too, with this nice shine that doesn't make it all greasy.
Also you don't need a ton of it, so it's gonna last. It's become my go-to. If you want a primer that not only keeps your hair safe but also makes it look awesome, try the Kerastase Paris Defense Thermique Blow Dry Primer. Highly recommend!

Loving it for my hair!
[This review was collected as part of a promotion.] First inpression is that the spray has a nice pink liquidly texture that spray evenly by the nozzle. Not only I feel safe knowing that I have the heat protectant before blow dry/style my hair, but also my hair became less frizzy and shinier. Remember to divide your hair into sections to apply the product evenly onto your hair. I have fine straight oily hair and if I overspray it, my hair gets super oily quickly. I am not a fan of its smell so I took a star off; the smell is kinda strong and quite chemical to me.
*I received the product from Buzzagent and Kerastase Paris for free in exchange for my honest review*

[This review was collected as part of a promotion.] I love love this product! I noticed how my hair is easily manageable after blow drying and ironing it. My hair is obviously shinier and smoother. Only reason I docked a star is cos of the smell— it smells good however it's a bit too strong for my liking.

Wasn't right for me
[This review was collected as part of a promotion.] After trying this free sample I will not be purchasing any more. It wasn't right for me. After a few sprays it left my hair greasy. Silky smooth but not right for my hair. The scent was very strong for me and I personally didn't like it. The scent did soften once I blow dried my hair which was great.

[This review was collected as part of a promotion.] This product is amazing. My hair has a lot of breakage from processing, heat and wearing my hair in a ponytail, this spray helped make my hair with the frizz and helped sleek my damaged parts. It smells amazing too!!

Made my hair frizzy
[This review was collected as part of a promotion.] I have used heat protectants on my fine hair for years but this one made my hair very frizzy for the 2 weeks I used it. I even used a de frizz product and it still was frizzy. I live in a climate that I wear staticky clothes so frizz is an issue but I have a go to heat protectant that does not cause frizz.

Smells good
[This review was collected as part of a promotion.] This Defense Thermique Blow Dry Primer is perfect to use before straightening my hair. It doesn't seem to use much of the product when applying and it smells so good before and after. While I cannot tell if it is actually "protecting", my hair feels smooth afterward.

Bon protecteur
J’adore l’odeur de ce protecteur thermal, il sent comme chez le coiffeur. Il protège les cheveux et laisse une belle brillance avec un brushing. Le prix est par contre très élevé, ça dépend donc des budgets de chacun.

Really good stuff
[This review was collected as part of a promotion.] I really liked how lightweight this product is while still giving my hair moisture. It made my hair smell really good while not overpowering. I've used this on my hair a few times now and my curl pattern comes right back with no frizz after adding heat.

This stuff is AMAZING!
[This review was collected as part of a promotion.] So I've had this now for a few weeks, as I wanted to really try it and see how it worked with my hair. I have to tell you you that this heat protection spray is amazing. It makes my hair very soft, manageable, looks healthy and easy to style. I have tried many heat protection sprays and they all leave my hair dry and crunchy. Not this one, this one is by far THE BEST I've ever used. Will I but it again, maybe. It is a bit pricey but they say you get what you pay for and who doesn't want their hair looking the best?
Thank you BuzzAgent for allowing me the time to really use this heat protection spray. I highly recommend it, it is THE BEST heat protection spray I have ever used!!

Amazing product!!!
[This review was collected as part of a promotion.] Love at first spray! I'm very picky when it comes to product smells, but this product smelled wonderful, I did not mind spraying it in my hair. Sprayed it straight out the shower to my ends and it made it easier to brush. I blow dryed then styled, it did not make my hair feel greasy what so ever! I have heavy thick hair and curls usually don't last very long, I was surprised when I had some curl the next day! Highly recommend this product!

I will buy this again
[This review was collected as part of a promotion.] I tried this Kerastase defense thermique on my hair because I use a hairdryer on my hair at least 5 days a week and also hair straighteners and heated brushes. I noticed my hair is becoming brittle and breaks off, and looks so dry. I apply this to towel dried hair and then dry with my dryer. I have used this for almost three weeks and my hair looks and feels stronger. It is less brittle and looks healthier

I'm thrilled to know this product exist.
[This review was collected as part of a promotion.] I've used this product over the past few weeks, and the first thing you notice is the luxurious smell, and also made my hair very very easy to comb through like silk, like easier than when I use a spray detangler, and the scent and softness lasted until my next wash.

This product is a winner!
[This review was collected as part of a promotion.] I have to say it delivers on all of it's claims! My hair is naturally wavy, coarse and frizzy if left to it's own. I used this for the past 2 weeks after shampooing and condtioning and it has made my hair bouncy, and the curls are defined with no frizz. It makes me happy to go without blow drying on busy days. And don't get me started on the scent...it is a treat for your nose. I mean, I LOVE the scent! My daughter has borrowed it too and she has hair texture similar to mine- can't say enough good things about it. The shine on my hair is great as well when it is dried and flat-ironed. This truly makes for less work, less, breakage, less headache when styling my hair. I would say the only thing that could be inmproved is maybe the feeling that it is a bit heavy -feeling if you use too much. All-in-all, I am so glad to be a part of this campaign, I truly enjoyed using the product and look forward to purchasing it in the future.
