During winter months in Iowa the blondes suffer terribly.
"Being a veteran stylist of 26 years, I've learned we lowlight in September. But as soon as Christmas is over I just strengthen the lows and add more blonde. There is no heat here til June, ha!! That's if we are lucky. Break the base with ash or cool level 9, a little more blue than level 10, highlight and call it spring!" ~ @lindawwtwolips
