Chenice has the Grey Oxicreme that gives an extra punch to resistant grey coverage. We also advise when you are struggling with grey coverage first try Chenice Natural series with 10 volume instead of 20 volume. If that does not solve the issue you can try the NN series for extra pigment. The question would be why the fadage? Are we lifting too much rather than deposit the pigment. Are we depositing enough pigment. Are we mixing and processing properly to get results. Are there residues from medication. What type of grey hair are we dealing with. What are they doing at home. Many causes to fadage. Learn more in a color class with us.
