Hi there! I was wondering about your colors that do not contain ppd. I use a light golden brown or golden blonde in the loreal brand to give my dirty brown color a lighter shinier color. Will your warm golden blond w/out ppd still lighten my hair and cover the few grays I have? I am new to the ppd issue and it scares me. I have been using hair color long term and am worried about my ppd exposure over time. Any helpful information would be appreciated. Thank you!
