Hi, Question please! I want to experiment with going blonde... Most likely with the Light Ash Blonde or Golden Blonde... I have been using Naturtint from Whole Foods lately... and have been going dark brown. I want a change. Will the Blonde color mixes be harsh on hair? Basically, What percentage of Peroxide is the Blondes from Eco Colors?? Im even interested in lightening my hair a few shades--- not really blonde blonde! Thank you! :)
