Sun Bum Blonde Tone Enhancer is a coloring treatment for blonde hair. Yellow and orange are perfect for sunsets, but not always for blondes. We love this leave-in treatment, which uses violet extract and argan oil to help bring out cooler tones and give our hair a little extra love. This Blonde Tone Enhancer leave-in treatment helps remove brassiness to bring out cooler blonde tones, hydrating and conditioning the hair. It helps control frizz and slows color fading, leaving hair smooth and shiny. Perfect for natural and bleached blonde hair.
