Genesis - Défense Thermique

Lightweight and effective

[I received this product in exchange for my honest review] This product is super lightweight and smells fresh! I think this spray did a good job protecting my hair from hear damage, my hair stayed soft and smooth!

Love the Smell

This heat protecting spray is amazing. It smells great and helps my hair to feel soft and shiny after drying. It protects from frizz. Not much is needed, just spray in a spritz or two all over hair and you’re good to go!

great stuff

great smell, makes my hair easier to comb and feel like it overall helps my texture. not too heavy on the hair which is really important to me, about to buy it a second time.

Heat Protectant

[I received this product in exchange for my honest review] Kérastase Heat Defense Crème provides excellent protection against heat damage while strengthening and smoothing hair strands. It leaves hair feeling soft, resilient, and frizz-free with a lightweight finish. Ideal for daily styling, it helps maintain hair health and shine, making it a must-have in any professional haircare routine

Good but too expensive

[I received this product in exchange for my honest review] It’s fine for what it is, it does pretty much the same thing as every other moisturizing heat protector, and it does work as you can see. But for how expensive it is, I just don’t think it’s worth the cost. Also it just squirts. I prefer to mist products like this so that it covers more of the hair without over saturating one section. Misting just gives a more even application and reduces product waste.

great for fine hair girlies

Fine hair girlies unite!! This is one of my favorite heat protectants. The mist on the sprayer is super fine so it allows the product to EVENLY coat my hair (which is one of my biggest gripes with the packaging on other products) so it doesn’t get over-saturated in certain areas. It’s also super lightweight so my hair doesn’t get weighed down or greasy looking when I’m done blow drying. Also smells amazing. Highly recommend

A must have

Absolutely love this product, smells really nice and works great on my hair! Will def be purchasing it again

Perfect night serum companion!

[I received this product in exchange for my honest review] Got this free from Influenster and started using it with my Kerastase night serum. Honestly obsessed — look how smooth my hair is!! it smells amazing, makes my hair soft, and I don’t get nearly as much breakage when I blow dry. Totally worth the price, like every other Kerastase product I’ve tried!

Smells super good

Smells super good! Maybe I’m just inexperienced but I noticed I had to soak my hair in the product for it to work.

Love!

[I received this product in exchange for my honest review] Love this protective thermal product! It smells good but also very light and not overpowering. Love the pink packaging and size. Great value. I use it as my only product on vlean hair and it helps with frizz all day! I don’t even have to use any other hair product.

Softer and more voluminous but greasy sooner too

[I received this product in exchange for my honest review] The consistency of this is similar to a leave-in conditioner spray, maybe a littler thicker. It smells lovely and it’s easy to spray over my hair. It seems like the main two benefits it advertises is heat protection and reducing breakage. I’ve used it a couple times now and I would cover my hair, brush, and then blow dry. I think in terms of breakage reduction, I didn’t notice any major difference. Maybe that’s something that takes long term use to see. I did notice my hair seemed more voluminous and softer after blow drying. My only complaint is that the times that I used it, it felt like my hair got greasy faster than normal. Usually I can go about three days without washing my hair, and it felt like I needed to wash it in two with this. I should also mention I don’t really focus the roots with this either so I found it to be strange.

Blow out transformation

[I received this product in exchange for my honest review] I’ve been using Kérastase Défense Thermique for a few weeks now, and I’m really impressed. My hair tends to get dry and frizzy when I blow-dry or straighten, but this feels so lightweight and smooths everything out without making it greasy or heavy. I noticed less breakage when brushing after heat styling, and my ends look healthier. It also makes my hair feel soft and silky, almost like I had a salon treatment. For me, it’s been a game-changer for protecting my hair and keeping it looking polished.
