KÉRASTASE Initialiste Scalp & Hair Concentrate — Advanced Leave-In Serum, Strengthens and Adds Shine

This lightweight serum targets the hair at its source — the scalp — to improve fiber uniformity and smoothness so lengths look shinier and feel softer. Formulated for regular at-home use, it absorbs quickly without greasiness and supports stronger-looking hair when used consistently. The formula is intended to hydrate the scalp while adding polish to the hair from roots to ends.

How does this concentrate reduce hair breakage?

The concentrate helps fortify hair fibers and restore surface smoothness, which lowers the friction and fragility that lead to breakage. By working at the scalp, it supports healthier strand formation and helps existing hair appear more resilient.

• Restores uniformity across hair fibers to prevent weak points
• Hydrates scalp to improve the environment for stronger growth
• Lightweight texture avoids weighing hair down while reinforcing strands

When and how should I apply the serum for best results?

Use on clean, towel-dried hair about three times per week for a routine that balances effectiveness with daily styling. Apply directly to the scalp in sections from front to back, gently massage to distribute, and leave in—no rinsing required.

• Recommended frequency: roughly 3x weekly
• Apply on cleansed, slightly damp hair for optimal absorption
• Massage from front to back to ensure even coverage; do not rinse

What visible benefits will I notice and how quickly?

With consistent use, hair typically looks shinier and feels softer, while individual strands appear less prone to snapping. Improvements in surface smoothness and texture can be noticed after several applications, with more visible strengthening over weeks of continued use.

• Added shine and illuminated lengths
• Softer texture from mid-lengths to ends
• Progressively reduced breakage with routine use

Is this suitable for my hair type and styling routine?

The formula is created to be lightweight and non-greasy, making it compatible with most hair types and daily styling habits. It can be integrated into color-treated, chemically processed, or natural hair care routines as a supplemental strengthening step applied at the scalp.

• Light finish works with fine to thick hair types
• Safe to use alongside color and styling products
• Designed as a leave-in treatment to fit existing regimens

Who is this for: KÉRASTASE Initialiste Advanced Scalp and Hair Concentrate is for anyone wanting to improve hair shine and softness while addressing fragility that begins at the scalp. It suits people looking for a non-greasy, leave-in serum to add polish and help strengthen strands over time, whether hair is naturally fine, textured, color-treated, or regularly styled.
