Grey hair lacks its natural colour pigments because the melanin production in the hair cells decreases over the years.

With the oxygen in the air, Re-Nature forms colour pigments similar to natural ones in the structure of your hair.

Depending on the number of applications and the processing time, wash after wash the colour pigments are restored and your first greys blend away after a maximum of 5 applications.

Re-Nature 1st GREY contains no hydrogen peroxide or oxidants - it is especially soft and gentle to your hair.
