Four silicone massage heads with 21 individual nodes work together to mimic the feel of real fingertips across your scalp, rotating clockwise and counterclockwise to boost circulation and work out tension. Beyond the scalp, it doubles as a massager for the neck, back, or anywhere else that holds stress.

Four speed and direction settings let you dial in anywhere from a light relaxing massage to a deeper, more thorough one. Cordless, rechargeable, and IPX-7 waterproof, so it works in the shower as easily as at a desk — one full charge lasts 7-10 uses. Detachable heads make cleanup simple. Dimensions: 3.7in x 3.7in x 4.9in. Weight: 14.2oz.
