Kerastase Genesis Defense Thermique 150ml

Kerastase Genesis Defense Thermique is a leave-in heat protectant that shields fragile hair prone to breakage during heat styling. In a single step, it hydrates, strengthens, and makes hair easier to comb, without weighing it down. If you're looking for effective protection that doesn't compromise volume, this formula is designed for you.

What it is

It's part of the Kérastase Genesis line, dedicated to hair prone to breakage and falling out due to fragility. The treatment has a fluid texture, so it distributes evenly through lengths and ends without leaving residue.

Who it's for

Suitable for fragile, fine, or weakened hair that is regularly subjected to blow dryers, straighteners, or curling irons. It's ideal for those who want to protect their hair fiber from daily heat while reducing breakage-related hair fall.

Benefits

• Thermal protection up to 220°C
• Reduces hair fall caused by mechanical breakage
• Strengthens the hair fiber from within
• Facilitates styling and reduces frizz
• Leaves hair silky and shiny

Active ingredients

The formula combines two key ingredients. Edelweiss stem cells (Leontopodium Alpinum Callus Culture Extract) protect against atmospheric agents, filter sun rays, and combat free radicals with antioxidant action. Ginger root (Zingiber Officinale Root Extract) has sebum-regulating properties and promotes regrowth by stimulating the sebaceous glands. These are complemented by coconut oil and hydrolyzed vegetable proteins to nourish and compact the hair structure.

How to use

• Before blow-drying: apply 2-4 sprays to the lengths and ends of damp hair
• After blow-drying: spray on lengths to tame frizz and add shine
• Do not rinse
• For a complete ritual, combine with Genesis Fondant Conditioner and Genesis Anti-Hair Loss Ampoules

Result

Hair is protected from heat, softer, and easier to manage. With regular use, the fiber appears more compact, breakage is reduced, and styling lasts longer. The product leaves no residue and doesn't weigh hair down.
