The Bioshev Professional Blue is an advanced technology product. It naturally lightens all hair, whether natural or dyed with any bleaching technique, reaching up to 7 tones. 

It does not create a cloud during preparation and reduces the risk of inhaling the powder. When mixed with Bioshev oxidant, it creates a thick cream that does not swell, does not run, is easily applied, and works immediately. The combination of keratin and silk prevents hair breakage. The lightening is controlled without any red or yellow tones. Result: clean, healthy, and shiny hair.
