Hair glows with restored supple softness and volume making it easier to style.  

  • Recommended for matured, thinning, and and greying hair.
  • Slows down greying process by preventing the loss of melanin.
  • Made in Spain. Fully recyclable packaging.

A dedicated ritual to make limp, devitalised hair thicker and fuller, the Densifique range features products with densifying technologies including hyaluronic acid and Intra-cyclane® to plump, hydrate and strengthen the hair.


  • Anti-Ox Cellular® complex: Protects hair and texturising polymers which work effectively to add body and bounce.
  • Stemoxydine: Targets stem cells to promote hair growth by regenerating the roots and scalp, increasing hair density.


Apply once a day on dry or cleansed and towel-dried hair. Divide hair into 5 partings and apply up to 7 sprays along each parting, directly to the scalp and the lengths. Massage gently. Do not rinse. Blowdry to activate the treatment.

Pro tip: Thanks to its precise nozzle, the Densifique applicator enables precise delivery to the roots and hair fibre on any kind of hair (short, medium, long).
