Ammonia-Free Powder Lightener - up to 7 levels of lift. System Blonde Powder Lightener is a high performance, ammonia-free powder lightener, perfect for both on or off-scalp lightening techniques. The gentle, yet powerful formula is much kinder to the hair, producing less swelling, porosity and damage, whilst achieving up to 7 levels of lift. System Blonde Powder Lightener does not contain any odorous ingredients, allowing the use of delicate Apple and Fresh Mint fragrances. The dust-free formulation mixes to a creamy consistency for easy application and does not dry or flake during the lightening process. System Blonde Powder Lightener’s incredible lifting ability means it should be used with much lower volumes of developer - achieve levels of lift with 3% (10vol) and 6% (20vol), that would normally be associated with using 9% (30 vol) and 12% (40vol) with traditional bleaches. For on scalp use, we recommend that only 3%(10vol) is used.
