SERI BLEACHING POWDER BLUE 500 GR

Use SERI Bleaching Powder with Farcom Professional Cream Developer 20,  30  or 40 vol. (depending on the desired degree of lightening) according to the following indicative ratio: Mix 1 part of bleaching powder and 2 parts of  Farcom Professional Cream Developer  in a non metallic bowl and apply to dry, unwashed hair. Check a small section of hair regularly until you attain the desired result (maximum recommended processing time 35 min.). Rinse off with warm water and wash with the SERI EXPERTS ASSIST neutralizing shampoo. The lower the concentration of the oxidizing cream, the gentler the lightening process. The lift level depends on the strength of the oxidizing cream, on the color, hair type and on the processing time.
