Dear Sir Madam, This is GerardoWaisbaum from ProCombs.com. I'm looking for products with the following specifications: We are looking to replace our existing product: a hair mask with color pigments. The purpose of this mask is to fight decoloration and color fading of color treated hair between serviced. The masks contains semi-permanent pigments (coal tar dye, per FDA definition). We need it initially in 4 tones: light blonde, silver blonde, grey and light blonde.
