It took many sessions to get my nephew’s hair this blond. This did not happen over nite. He has super course thick hair. Very black and he had res pigment in it from a old color job he got done at Fantastic Sam’s. Use cool or cold water when shampooing your bleached hair. Let it air dry if possible and use a purple shampoo once a week. I still have a couple of more sessions to go before I get it to the perfection that I want for my satisfaction.
