Kerastase Masque Vert Chroma Neutralisant Hair (Dark Brunette Perfecting) 150ml

Kérastase Masque Vert Chroma Neutralisant (150 ml)
A color-correcting mask crafted specifically for dark brunette or deep brown color-treated hair, this treatment neutralizes unwanted red and copper tones while deeply hydrating and strengthening the fiber.

• Instantly cools red undertones for a more neutral, deeper brunette shade 

• Intensifies hydration (+89%) and boosts fiber strength (+53%), reducing breakage 

• Key actives: tartaric acid to protect and enhance shine, plus Centella Asiatica for fiber repair 

• Use weekly (1–5 min on towel-dried hair), gloves recommended—it can stain light hair or surfaces
