How to use it

After shampooing, apply the mask to wet hair, distributing it evenly from lengths to ends.

Dose with precision: its serum-like texture penetrates instantly, so a small amount is enough to envelope the fiber.

Leave the formula on for 5 minutes to saturate the core of the hair, then rinse thoroughly.

Frequency: Integrate this intensive treatment into your routine 1 to 2 times a week to maintain maximum resistance.

Ingredients and their benefits

• Citric Acid: This low-molecular-weight active ingredient goes straight under the cuticle to strike at the core of the fiber. It penetrates deeply to rebuild and shield weakened internal bonds, restoring a solid structure and raw strength to the hair from the inside out.
• Squalane: This biomimetic active ingredient perfectly mimics the hair's natural lipids to instantly fuse with the fiber. By restoring the protective hydrolipid film, it seals moisture into the core of the cortex to create a barrier against dehydration and prevent future damage. Its smoothing action immediately softens the hair texture, easing detangling to eliminate breakage during styling.
