I have a new color client who wants full head vibrant red, I have done a phone consultation (face to face consultation is today) and found out she's previously been using box dyes which have grown out to the mid lengths, her base is a 4 an these box dyes are various shades of brown, also she has been using an OTC shampoo and conditioner! Her hair is very long and thick, I am going to tell her to use a deep cleansing shampoo all week before I do the color to get rid of product build up, I was going to use bleach an 3% to lift it slowly an try an get rid of the box dye build up on the ends an do the roots last, do you think I should do this or a bleach bath? Then put the red on which we will decide on today, obviously will be retailing her the correct professional shampoo and conditioner any ideas welcome geeks
