Kérastase – Chronologiste Longevity Potion – 30 ml

Apply the potion directly to your scalp, section by section, after shampooing and towel-drying your hair. Massage it in gently and leave it on without rinsing — the formula absorbs immediately and leaves no residue. For best results, use it consistently over a period of one month.

The potion is powered by Caviar of Longevity — a potent blend of two active ingredients:

• 3% Pro-Xylane™ — a biomimetic molecule that supports scalp cell renewal and strengthens the hair fibre from within.
• Ochrophyta algae — a marine extract known for its revitalising and protective properties on scalp cells.

Together, they penetrate 10 layers deep into the scalp to optimise up to 3 billion scalp cells and deliver targeted revitalisation at the source.

Yes. The Chronologiste Longevity Potion is suitable for all hair types, including coloured, highlighted, or chemically treated hair. Its leave-on formula targets the scalp rather than the hair shaft, so it will not affect colour vibrancy or interfere with chemical treatments.

The potion is designed for daily use during a dedicated one-month treatment. Results build progressively over time:

• After 1 application: immediate scalp hydration and a visible increase in hair diameter.
• After 1 week: 61% of users report their scalp feeling healthier.
• After 2 weeks: 82% experience a renewed and regenerated sensation.
• After 1 month: 70% notice hair that looks healthier and more resilient.

Not at all. The lightweight serum texture absorbs instantly into the scalp, leaving no residue and no greasy feel. It is formulated to work comfortably as part of your daily routine without affecting the appearance or texture of your hair.
