Its flexible, bendy bristles made this palm-size brush an all-out hit, gliding snaglessly through hair for minimum breakage and maximum shine, and now there’s a new version: Turn it on and a pulsating, 360-degree scalp massage detangles, exfoliates, and stimulates circulation and blood flow (which can help with hair growth). It feels absolutely fantastic, is totally waterproof—perfect for use in the shower—and works on all hair types, from fine and fragile to thick, curly coils and even extensions.

• Includes: shower holder and travel pouch

Our tip: In the shower, pump hair treatment onto the brush and gently massage, cleanse, stimulate, and relieve tension in the scalp as you wait for your treatment to work.
