How does it work?
Your fingertips miss spots and your nails can scratch. The soft, rounded tips reach through your hair to the scalp, lift buildup and spread your shampoo evenly, while giving you a massage that feels as good as it works.
How do I use it?
In the shower, apply your shampoo, then move the brush in small circles across your scalp for 1 to 2 minutes. You can also use it dry with a scalp oil to massage it in.
Is it gentle on the scalp?
Yes. The rounded tips massage without scratching. Use light pressure and let the brush do the work.
How do I clean it?
Rinse it under warm water after each use and let it air dry.

Your fingertips can only do so much.
Most of us wash our hair, not our scalp. Product stays on the surface, buildup stays at the root. This brush reaches through every layer of hair to clean the scalp itself, so your shampoo works where it’s supposed to. Two minutes, small circles, and a scalp that feels truly clean and awake.
