Developer 30 volumes

Sheis Beauty Developers are hydrogen peroxide-based developers in different concentrations (3%, 6%, 9%, and 12%) that allow hair to be lightened between 1 and 4 shades depending on the volume selected. They are ideal for mixing with permanent dyes or for bleaching processes, achieving everything from gray hair coverage to intense lightening. The choice of volume depends on the desired level of lightening and hair type. Use: Mix in a 1:1 ratio with Sheis Beauty dye or bleaching powder. Apply to dry, unwashed hair, starting at the roots and extending to the ends. Leave on for 15 to 45 minutes, depending on the lightening level and volume used. Monitor the process constantly to prevent damage. Rinse with plenty of water and proceed with your usual post-coloring treatment.
