What Is It?

KERASTASE Spécifique Potentialiste Balancing Scalp Serum 90ml is a microbiome-focused leave-in treatment designed specifically for the scalp rather than the hair lengths.

KERASTASE describes Potentialiste as its universal defence serum for unbalanced scalps, powered by microbiome science. Its purpose is to help fight scalp imbalance while preserving the protective scalp barrier and providing a soothing, refreshing effect.

This makes Potentialiste particularly useful for customers who don't necessarily have one single scalp problem.

Their scalp may alternate between:

Oiliness → Dryness → Sensitivity → Discomfort

Potentialiste takes a broader scalp-balancing approach.

The concept is:

Balance → Soothe → Strengthen Barrier → Protect → Revitalise

Is Potentialiste a Hair Growth Serum?

No — I would not market it as a hair-growth or anti-hair-loss serum.

This distinction is important for Peggymou.

Potentialiste → Scalp balance + microbiome + soothing + barrier support

Genesis / Spécifique Anti-Chute treatments → More appropriate when the customer's primary concern is hair fall or thinning.

KERASTASE officially positions Potentialiste as a balancing scalp defence serum, not a hair-regrowth treatment.
