Recommendations to stripes:

We do not recommend higher h2o2 than necessary. H2o2, or peroxide as it is also called, determines the lightening of the hair. We have produced peroxide in different strengths where 3% lightens 1-2 tones. 6% 3-4 tones. 7.5% about 4 tones. 9% 4-5 tones. 12% lightens up to 7-8 tones. 12% is used only in virgin, strong, dark hair. If you have chemically treated or dry hair, do not use stronger than 6%.

We always recommend toning over the stripes to neutralize the color.
