Genesis - Défense Thermique

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.

Easy Protection and Shine

[I received this product in exchange for my honest review] I really enjoyed this smoothing heat protectant spray. It has a subtle scent and is easy to apply. After blow drying, curling, and touching up my hair it still felt healthy and protected.

Like that it helps with breakage

I liked this product. I have somewhat thinner hair and it can end up being damaged by things like heat (hello blow drying) and hair ties. So something that adds a layer of protection on the days when I do need to dry my hair before heading out the door is very much welcomed. I found that the spray on this was a bit wilder than I originally expected, but I also just chopped off 12+ inches of hair so that may be me still adjusting. Not a crazy strong smell, this product did drop the percentage of breakage I had been seeing. Happy to keep using this when I dry my hair.

Soft and smooth

This product smells so good and helps reduce hair frizz!! It also made my hair softer :) very easy to use as well and comes out like a fine mist! Love that it protects from heat

Nice addition to my hair routine

It smells good and is easy to use. The bottle lasts a long time. It also gives a little bit of a lemon scent. Heat protection is always a nice addition to your hair routine.

Good for fine hair

[I received this product in exchange for my honest review] This product is nice and lightweight, with a pleasant but not overpowering scent. It doesn’t weigh down my oily fine hair and keeps my ends from being damaged due to constant heat from my hairdryer. The packaging is sleek and I would consider this a good value for how long the bottle will last!

Great heat protectant

[I received this product in exchange for my honest review] This stuff is great! Sprays well and distributes after brushing in hair. Packaging is simple. Ingredients are ok and scent is outrageously strong. It protects my hair from heat but not quite sure it’s worth the price.

I received this for free from Influenster in exchange for my honest review. This smells amazing and it works well especially after I got my hair colored and it needed moisture.

Makes my hair look shiny and less frizzy

[I received this product in exchange for my honest review] I like how my hair looks and feels after using the Kerastase Genesis Defense Thermique Heat Protecting Spray. It helps create volume, makes my hair look shiny and less frizzy. The spray is light and absorbs quickly, so it doesn’t feel greasy or heavy after using. I also like the smell of the product. I paired it with the Kerastase Genesis shampoo and conditioner and received great result.

Smells delicious, leaves hair feeling fabulous!

[I received this product in exchange for my honest review] Let’s talk smell, this smells go good! The first time I used it I really debated on whether or not I needed to wear perfume that day. The nozzle sprays very well and evenly. My hair did not feel heavy or weighed down. It made my hair very soft and shiny. I do not blow dry my hair often but when I do I will reach for this again!!

[I received this product in exchange for my honest review] Smells absolutely amazing! A little bit goes a long way for the price and the product does a great job of reducing frizz from constantly using my hair straightener. The packaging is simple and the product itself is a bit watery, so be careful when dispensing.
