Living Proof Perfect Hair Day Dry Shampoo contains fast-absorbing powders that soak up oil and sweat. Great for all hair types and colors, a patented OFPMA molecule reduces the surface friction on hair—leaving virtually no visible residue or powdery build-up—making it easy to remove the powder. Odor neutralizers eliminate unwanted smells, and a time-release fragrance releases a light, refreshing, long-lasting scent.
