Since you have already used a demi-permanent (deposit only) color, it would be wise to have your stylist use a an artificial pigment remover first. They are very gentle on the hair and will only remove the demi color. At that time you can have the hair lightened, using permanent color with a 20 volume developer only. Your hair porosity will be increased from the TR and permanent color, but since your are switching to BKT, you should see great results.
