Izumi Tonic Strengthening Shampoo for Thin Hair

Available from Bowie Salon & Spa when we last checked. Sold from the shop’s own store; the price there is the one that counts.

This lightweight, transparent shampoo inspired by Japanese rice water tradition gently cleanses while strengthening and thickening fragile hair. Formulated with rice water to help repair damage, it leaves hair up to 30x stronger, reduces split ends, and adds fullness without stripping hydration.
