Schwarzkopf BlondMe Premium Developer 9% (30 vol) is an oxidizing agent crafted to accompany the BlondMe line’s bleaching and coloring products. This premium developer is formulated to deliver optimal results when lightening or tinting blonde hair. Key points: it contains 9% hydrogen peroxide, which corresponds to a 30-volume strength, offering more lift and stronger color deposition than lower-volume developers. It’s well suited for achieving higher lightening levels and for providing effective color coverage on natural hair or darker bases. The recommended mixing ratio is 1:1 with BlondMe bleaching or coloring formulas, with exact amounts varying according to the amount of product needed. The formulation has a creamy texture that enables smooth application and even distribution, helping to achieve consistent lightening or coloring results throughout the hair.
