Question
Posted on: March 6 2013We got the following preparation: Hydrogen peroxide 6% (20V %0) 50g Ammonium hydroxide to pH 9.5 Water up to 100ml hairs over lip decolouring
Is This concentration sufficiently high to bleach the hairs?
Answer
To begin with, my knowledge is the concentrated solution hydrogen peroxide or Perhydrol 30% or 100 volumes. Just oxygen water is 3%. I thought that for white colors of her 10% was used. But for the lip, we may have to be more cautious. So I think 6% perhydrol 50g will be sufficient.
