Essential in My Hair Care Routine.

[This review was collected as part of a promotion.] Genesis Défense Thermique by Kérastase exceeded my expectations. It's an excellent product: it leaves the hair soft, silky, and very manageable from the very first application. I've also noticed that it significantly reduces friction while detangling, which helps prevent breakage and makes the styling process much easier.

Perfect protection

[This review was collected as part of a promotion.] I love this kerastase protecting spray that sort of laminates the hair inorder to protect it from the heat of blow drying. It gives the hair smoother and glossy finish. I don't.style my.hair without applying it first to make sure my hair is safe from damage caused by frequent styling and blow drying.

Perfect Heat Protection Without Weighing Hair Down

The Genesis Defense Thermique Heat Protecting Spray is amazing. I use it before blow-drying or heat styling, and it leaves my hair feeling soft, smooth, and protected—never sticky or heavy. I've noticed less breakage and frizz, and my hair looks healthier and shinier after styling. It detangles beautifully and helps my hair feel stronger, especially at the ends. Plus, the scent is light and luxurious, just like a salon experience at home. This spray gives me confidence using heat on my hair while keeping it looking and feeling healthy. I highly recommend it if you want protection without sacrificing softness or volume.
