Dry Shampoo Foam Hydrate & Shine for dry or brittle hair. Our unique foaming dry shampoos are basically magic in a can. It works without water but help cleanse your hair from dirt and oils to give you that just-washed-virgin-hair-feeling. No more leftover powder residue, just gorgeous, long-lasting hair for days. We decided to go with a foam version rather than a spray for that extra, luxurious feeling.
