Important information refresh bright lengths

Refreshing light lengths:

If you do not want your lengths to become darker, it is very important to use a higher strength of h2o2, for example 3%, 6% or 7.5%. Lengths and ends always attract more cold pigments and can quickly become darker and colder if you use the same color from root to tip. We recommend using a slightly lighter tone in the lengths so that the color does not become darker.
