2016 - 28. Cold and Icy… Ash Blonde As you might have noticed, orange undertones are not really a thing now. Today, we try really hard to maintain a purple base, because it is turning into the hair color trend of the decade. So, start with a purple-based ash brown and slowly develop into icy blonde, purple-based again. It’s a refreshing icy look that will be like a chilly sea breeze in the heat of the summer. Lots and lots of purple shampoo needed, for sure!
