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

This lightweight scalp and hair serum targets weak, breakage-prone hair by working at the scalp to improve fiber uniformity and smoothness. Formulated to be non-greasy, it hydrates without weighing hair down and helps hair look healthier and more luminous with regular use. Recommended application is on clean, towel-dried hair three times per week to support stronger hair growth and improved manageability.

How does this serum reduce breakage and strengthen hair?

The concentrate contains active ingredients that focus on reinforcing the hair fiber beginning at the scalp, improving the uniformity and smoothness of each strand. By restoring fiber integrity, it lowers the chance of mechanical breakage and split ends during styling and daily wear.

• Works at the scalp to support stronger hair formation.
• Enhances fiber uniformity to reduce weak points along the strand.
• Leaves hair smoother to resist friction and breakage.

Will this serum make my hair look shinier and feel softer?

Yes — the formula is designed to illuminate hair and impart softness from mid-lengths to ends without creating a greasy finish. The result is visibly shinier hair that moves more freely and feels silkier to the touch.

• Light-reflecting finish for added shine.
• Hydrating components that smooth the cuticle for a softer feel.
• Non-greasy texture preserves natural movement and volume.

How do I use KERASTASE Initialiste for best results?

Apply the serum to clean, towel-dried hair about three times per week, working from the front of the scalp to the back. Dispense the recommended amount, part the hair, place drops directly onto the scalp, and massage to ensure even distribution; leave in — no rinse required.

• Use on cleansed, towel-dried hair for optimal absorption.
• Direct application to the scalp then massage evenly across sections.
• Leave in place; do not rinse. Follow routine three times weekly.

What texture and finish should I expect after application?

The serum has a lightweight, hydrating texture that absorbs quickly, adding subtle texture without slickness or residue. Hair should feel nourished at the roots and softer along the lengths while maintaining a natural, non-oily finish.

• Fast-absorbing, lightweight serum consistency.
• Adds hydration and texture without weighing hair down.
• Delivers a luminous finish without a greasy feel.

Who is this for: KERASTASE Initialiste Advanced Scalp and Hair Concentrate is suited for anyone experiencing delicate, thinning, or breakage-prone hair who wants to improve strength, shine, and softness starting at the scalp. It’s ideal for people seeking a leave-in treatment that fits into a regular haircare routine, works under styling products, and supports healthier-looking hair without added oiliness. If you shampoo and style frequently or notice fragility at the roots, this serum is formulated to reinforce the hair fiber and improve overall manageability when used consistently.
