Product details

KÉRASTASE Initialiste is an advanced scalp and hair serum designed to boost shine, soften lengths, and strengthen hair to reduce breakage starting at the scalp.

This lightweight, leave-in concentrate targets the scalp and hair fibers to improve uniformity and smoothness. Formulated to be applied to clean, towel-dried hair three times a week, it nourishes without adding weight or grease while enhancing hair radiance from roots to ends.

How does this serum improve hair strength and reduce breakage?

The formula works at the scalp and along the strands to reinforce fiber cohesion and minimize points of weakness. Regular application promotes a smoother hair surface which makes hair less prone to snapping during styling and daily handling.

  • Active ingredients aimed at strengthening hair fibers
  • Restores surface uniformity for fewer tangles and breakage
  • Leave-in serum that protects during mechanical stress like brushing

How should I apply KÉRASTASE Initialiste for best results?

Use on clean, towel-dried hair about three times per week. Apply directly to the scalp from front to back, massage gently to distribute, and leave the product in—no rinsing required.

  • Apply to scalp in sections for even coverage
  • Massage to activate ingredients and spread along lengths if needed
  • Suitable as part of a weekly routine—no heat or rinse required

Will this serum make my hair feel greasy or heavy?

No, the Initialiste concentrate is formulated to deliver hydration and texture without a greasy residue. It provides lightweight nourishment so hair feels softer and looks illuminated while retaining natural movement.

  • Non-greasy finish preserves volume and bounce
  • Hydrates scalp and strands without weighing hair down
  • Leaves a luminous shine rather than oily gloss

When can I expect to notice improvements in my hair?

Visible benefits like increased shine and smoother lengths can appear after a few applications, while measurable reductions in breakage and stronger-feeling fibers develop with consistent use. For optimal effect, follow the recommended three-times-per-week routine.

  • Immediate: enhanced softness and shine after first uses
  • Short term: easier detangling and smoother texture within weeks
  • Ongoing: progressive strengthening and less breakage over continued use

Who is this for: KÉRASTASE Initialiste Advanced Scalp and Hair Concentrate suits people with fragile, dull, or breakage-prone hair looking for a lightweight, leave-in treatment that targets the scalp and hair fiber. It works well for all hair lengths and types that need added shine, softness, and resilience without heavy oils or sticky residue.
