This new-formula peroxide developer is suitable for all hair types. It contains Limnanthes alba plant oil that coats the hair with a protective layer, gives it volume and strength, acts as an anti-static and prevents drying. Use 6% / 20 Vol. peroxide to change the shade of dyed hair and get darker tones, to cover greys and highlight a warmer shade of toner; if you want to get your hair three shades lighter, cover greys or emphasise a warmer colour with toner, use 9% / 30 Vol. peroxide. 9% peroxide is also recommended for first hair colouring. Use 12% / 40 Vol. peroxide to get your hair four or more shades lighter, i.e. for super lightening and grey coverage.
Use this peroxide developer with Velvettone hair colour at a 1:1.5 mixing ratio.
