The "grey head hair" consists of a mixture of normally pigmented and colourless hair. The degree of graying depends on the percentage of normally pigmented and colourless hair.
Rausch's sage shampoo counteracts the yellow cast. It gives a light shine, provides moisture and ensures good combability of the hair. Additionally the blood circulation of the scalp is promoted and vitalized. The scalp and the hair are strengthened.
The shampoo has a strong blue color even during the foaming of the hair. This colour is normal and can be washed out without leaving any residue.
