Healthy hair begins at the root.
The System

A system, not a single product.

Two objects, each designed for one part of the job. The treatment goes where your hair starts. The tool works it in.

What’s inside

Four botanical oils. One clean feeling.

Massaged in before you wash, then rinsed out with your shampoo, it helps lift away product buildup and loose flakes so your scalp feels clean and fresh.

  1. Peppermint

    Cool and awake

    A tingling, cooling feel the moment it meets the scalp.

  2. Tea tree

    Fresh and clarifying

    A crisp, clean feel through the scalp and roots.

  3. Lavender and sweet orange

    Calm and bright

    Soothing and uplifting scents that turn a few minutes into a ritual.
