KERASTASE Chroma Absolu Soin Acide Chroma Gloss 210ml

KERASTASE Chroma Absolu Soin Acide Chroma Gloss 210ml is a professional high-shine rinse treatment for all types of colour-treated hair, designed to resurface the hair fibre, reduce porosity and dramatically improve shine, softness and colour vibrancy. Its lightweight liquid texture transforms into a cream when activated with water, helping smooth and seal the cuticle without the heaviness of a traditional mask.

Enriched with Lactic Acid and Centella Asiatica, it is particularly useful for coloured hair that has become dull, porous, rough or less vibrant between salon appointments.

KERASTASE reports 94% more hydration, while hair can be 96% stronger when Soin Acide is combined with a leave-in. In the KERASTASE Bain + Soin Acide routine, 88% of colour intensity was preserved after 6 weeks.

High-shine treatment – Creates a smoother surface for dramatically shinier-looking hair.

Resurfaces the fibre – Helps reduce the rough, porous feel associated with colour-treated hair.

Boosts colour vibrancy – Lactic Acid helps trap dulling minerals and enhances the appearance of colour.

Lightweight finish – Delivers gloss and softness without behaving like a heavy traditional mask.

What Is It?

KERASTASE Chroma Absolu Soin Acide Chroma Gloss 210ml is a resurfacing rinse-off gloss treatment for colour-treated hair.

This is important: it is not simply another conditioner or hair mask.

The liquid formula transforms into a cream when activated on wet hair. It works on the hair fibre to help smooth and seal the cuticle, resulting in greater softness, shine and a less porous surface.

Its role is:

Resurface → Reduce Porosity → Smooth → Boost Shine → Enhance Colour Vibrancy

This gives us a very strong customer proposition:

Salon-like gloss for colour-treated hair—in an at-home rinse treatment.

What Makes It Different?

Colouring can increase hair porosity and leave the surface of the fibre less uniform.

When the cuticle becomes rougher, hair can:

• Reflect less light
• Look duller
• Feel rougher
• Become more prone to frizz
• Lose the appearance of fresh, vibrant colour

Soin Acide Chroma Gloss targets this by resurfacing and sealing the fibre, creating a smoother surface that reflects more light.

Soin Acide Chroma Gloss vs Masque Chroma Filler

These should have clearly different positions on Peggymou.

Soin Acide Chroma Gloss → Choose when the main priorities are shine, smoothness, colour vibrancy and reducing porosity.

Masque Chroma Filler → Choose when sensitised colour-treated hair needs a richer strengthening and nourishing mask, particularly medium-to-thick hair.

So:

Dull coloured hair + want incredible shine → Soin Acide Chroma Gloss

Damaged/porous coloured hair + want richer intensive care → Masque Chroma Filler

KERASTASE also states Soin Acide can be used once weekly instead of a Fondant or Masque, or before one when additional care and shine are desired.
