Genesis - Défense Thermique

Exceptional

I literally LOVE this stuff!!! The smell of it is just so dang good, I can’t get enough of it. I’ve been using this for about 3 weeks now and so far so good. My hair is so easy to brush after spraying this on my hair before blow drying. It helps keep my little new growth crazy stubborn stray hairs down which is HARD for a product to get done! I recommend this product to anyone looking to help strengthen, smell good, dry damaged hair.

Great product

This protectant spray is excellent! It smells great and works very well with a curling iron! Would recommend and would purchase in the future. Received free for my honest feedback.

Soft and nourished

[I received this product in exchange for my honest review] A lovely gentle scented hair protectant that leaves my hair nourished and soft. I only blow dry my hair sometimes but I definitely notice the difference. I would have preferred a pump head over a spray nozzle but it’s great otherwise.

very good, works well

[I received this product in exchange for my honest review] i regularly use the dyson airwrap so i have been testing this product alongside it - i’ve noticed that the product works well, the scent is pleasant and my hair feels softer upon using it. i can’t say much for how effective it is for heat damage but it has a nice consistency and texture. i’d recommend.

Effective and Smells Nice

[I received this product in exchange for my honest review] I was really excited to try this as I am already a fan of the brand. I usually don’t use heat on my hair because I’m trying to limit the damage. However, this was effective as a protectant and prevented frizzing. It also made my hair shiny. It smells good, too!

Best of the best!

[I received this product in exchange for my honest review] I used this product years ago and honestly don’t know why I quit buying it. When Influenster sent it to me to review, my love was rekindled immediately! Though I don’t heat treat more than once or twice a week, I can feel the difference in my hair’s softness and texture.

Amazing results for styling

Always looking for a heat protectant that also doubles up with other benefits. This spray makes your hair so smooth and smells amazing. It makes my hair super soft and helps the blowout hold well and last.

Stronger, Softer Hair That Survives the Heat

[I received this product in exchange for my honest review] I’ve been using the Genesis Defense Thermique Heat Protecting Spray from Kérastase, and it has made a noticeable difference in my hair. The spray is really lightweight, so it doesn’t make my hair greasy or heavy. I usually apply it before blow-drying or straightening, and it gives my hair a smooth, silky finish with less frizz that actually lasts all day. What I like most is that it protects my hair from heat styling while also keeping it nourished and shiny. My hair feels stronger, looks healthier, and I’ve noticed fewer split ends and less breakage when brushing. It also helps keep my hair conditioned and soft, which is a big plus since I style it often. Overall, it’s an easy step in my routine that makes a big difference especially if you want to keep your hair protected, smooth, and less prone to damage from daily styling.

Healthy hair

Kérastase Genesis Défense Thermique is my new go-to heat protectant—lightweight, smells amazing, and leaves my hair smooth, shiny, and frizz-free while protecting up to 450°F. A bit pricey, but worth it for strong, healthy hair.

Leaves my hair soft and smooth

[I received this product in exchange for my honest review] I have really enjoyed using this heat protecting spray. I have naturally curly hair so it takes some heat abuse from time to time when I decide to straighten or blow-dry it. This spray is very easy to use and seems to evenly distribute a fine mist over my hair. This spray has a nice scent that isn't too overpowering for me. It feels very lightweight, even when I feel like I've used a lot. After using my heat source, where it be my hairdryer or straightener, my hair is left soft and smooth with a bit of shine. I'm really enjoying this product. This has quickly become my go-to spray to help protect my hair from harmful heat!

Great all in one product

I’m always looking for ways to help the health of my hair due to being a natural brunette and getting highlights to go lighter. This is such a great all in one product. It helps with frizz, but the main benefit is the heat protection, which leaves a soft shine that doesn’t make my hair look oily. I like the spray bottle because I can also spray it into my hands and then apply it to my hair.

Nice but Not a Fave

[I received this product in exchange for my honest review] I love the scent of this heat defense spray. It leaves my hair smelling fresh. I use this while my hair is damp before blow drying and it helps prevent damage. The texture is creamy and easily absorbed, I’ve price-checked this spray against others on the market and it’s much pricier. Honestly, I’ve found other options that work as well or better for half the price.
