Hair Youth Activating Serum. STEMOXYDINE® + ANTI-OX CELLULAR


Bleaching is the first visible effect of time on the hair. Unfortunately, a hair that loses its color also loses its greatest qualities. It becomes thinner, becomes rough, less easy to discipline and dull. The coloring allows, of course, to sublimate the material and to hide the gray hair but does not give back to the fiber all its lost qualities. In order to prevent the effects of time on hair quality, Kérastase creates Densifique Youth Serum, its first hair youth activator that compensates for the loss of quality in gray hair. Thanks to the unique alliance of Anti-Ox Cellular and Stémoxydine®, Densifique Youth Serum fights both against the thinning of the fiber and the disappearance of melanocytes, thus delaying hair depigmentation.

The words of Eric Pfalzgraf, from the Coiffirst salons: “The Densific Youth Serum is a revolution. It is in a way the 1st anti-wrinkle treatment for the hair. I recommend it after each shampoo, on all types of hair, to prolong the intrinsic qualities of young hair ”.

Application :

This exceptional treatment is applied after shampooing to the scalp and towel-dried hair:

• Spray 8 pressures directly on the scalp, section by section.

• Massage with fingertips over the entire scalp.

• Apply between 6 and 12 pressures on the whole of the hair according to the length of the locks and comb in order to distribute the product on the whole of the hair. Do not rinse.

• Proceed with styling. Can be used every day alternately with Initialiste to prolong the intrinsic qualities of a younger hair or after a 3-month cure of Densifique vials to prolong the benefits of Stémoxydine®.


An exceptional formula combining the most powerful antioxidant complexes, the Anti-Ox Cellular, with the power of Stemoxydine®.

• Anti-Ox Cellular: used for the first time on the scalp, this complex helps preserve melanocytes, cells capable of producing melanin, thus delaying the effects of time on the hair. It brings together four ingredients chosen specifically for their strong antioxidant power: ferulic acid, vitamins C and E, a UV filter.

• Stémoxydine®: used as a cure, this molecule significantly increases hair density.

• Ceramide: associated with a texturizing polymer, it restores the shine and flexibility of the fiber. From the first day of application, the fiber radiates with its shine, flexibility and radiant volume. From three months, a new capillary density is deployed.
