I am a stylist with contact dermatitis loving that I can color hair again using Eco colors. Wish I could find a salon in my area that uses Eco Colors so I can work there. Right now I'm working part time at home. I am having some trouble with skin using the Rosemary Lightener. I am able to keep it under control but long term I think it will get worse. What do you recommend I use for clients who need a lightener to get the blond shade they are looking for? For example, clients who have regrowth 7 or lower looking to be around 9 or 10.
