- A dry shampoo that cleans beyond ordinary dry shampoos. It’s powered by our patented Healthy Hair Molecule (OFPMA) and Triple-Action Cleaning Technology that: absorbs and removes oil, sweat and odor; makes your hair look, feel and smell clean; works on all hair colors because it leaves virtually no visible residue or powdery build-up behind; has a time-released fragrance to deliver a light, clean scent throughout the day. Perfect hair Day (PhD) Dry Shampoo is ideal for all hair types. It is silicone-free. Safe and formulated for color and chemically treated hair. Shake well. Hold canister 6 to 10 inches away from dry hair, then apply Dry Shampoo section by section in a sweeping motion to dirty or oily areas. Wait 30 seconds for powders to activate and cleanse, then remove them by massaging your hair with your fingers, or brushing your hair. Apply more if needed (just make sure to shake the can again). Tip: See a little white residue? No worries, that's the cleaning in action as the oil and sweat are absorbed by the dry shampoo. Just wait 30 seconds and brush gently to remove. Dry Shampoo is compatible with all Living Proof care and styling products. The powders in dry shampoo may stick more to resin-base products (i.e. products that have hold). The powders should still be easily removed. If you do still see powders after using fingers and/or brush, use a blow dryer for more thorough removal.
