Rated 1 out of 5 by from Dry hair after usage Dries our hair so badly. Tried contacting customer service but did not respond. Really a shame…

Rated 5 out of 5 by from great ! smells great , and i mostly use it to protect my hair from the sun. i haven’t noticed any new damage, and my hair has been getting healthier (however with other products, too, not only this one), so it does its job!

Rated 3 out of 5 by from Could be better Smells good , however Im not sure it doesn’t really do much in terms of heat protecting , it could be better and also dries out my hair :(

Rated 5 out of 5 by from Perfect [This review was collected as part of a promotion.] Hair feels softer, doesn’t weight it down when you put it in Easier to get my hairbrush through my hair

Rated 3 out of 5 by from Changed formula? I’ve been using the genesis range for a year, after experiencing significant seasonal hair fall last autumn. It worked wonders at the time but now my hair is feeling really dry and frizzy, and cannot hold a style. I washed and dried without using this spray recently as I was having my hair put up for a wedding, and it did blow dry much easier, so I’m not sure if it’s the spray that’s contributing towards the dryness. It was out of stock for a while so I’m wondering if the formula has changed? Going to switch to a moisturising range for a while and hope that makes a difference! A shame, as I’ve recommended the range to lots of friends, but my hair is just so parched right now it needs a change!

Rated 3 out of 5 by from Good lightweight protection but annoying nozzle I like the Kérastase Genesis Défense Thermique. It feels really lightweight and doesn’t leave any residue, which I love. The only downside is the nozzle, it’s a bit awkward to use and makes it hard to spray evenly. Otherwise a good heat protectant.

Rated 5 out of 5 by from Perfect for brittle hair Makes my hair feel so soft and silky after use! The spray bottle can on occasion get stuck but for how good the product is it’s not really a problem for me! For reference I have been healing damaged and thinning hair that had a serious breakage problem however since using this my hair has been silky soft with minimal breakage

Rated 5 out of 5 by from Amazing I love to use this on my wet hair after washing. It detangles and leaves it super soft.
