Hair care that feels like a ritual

  • For all hair types
Inside every drop

The science, made simple.

A quick guide to what's in your bottle and how it cares for your hair.

What is a serum?

A serum is a light, concentrated formula made to absorb. Unlike heavy oils or rinse-off treatments, it sinks right into the scalp, so there's no greasy feel and nothing to wash out.

What is a peptide?

Peptides are short chains of amino acids, the same building blocks that make up keratin, the protein your hair is made of. Ours are copper tripeptide-1 and biotinoyl tripeptide-1.

Each bead is an amino acid. Link a few together and you get a peptide.

What peptides do for your hair

  • Supports a healthy scalp

    Paired with niacinamide and allantoin to help your scalp feel calm and balanced.

  • Fuller-looking hair

    Hair-support peptides help hair look thicker and fuller from the roots.

  • Less breakage

    Rice protein and panthenol condition strands to help reduce breakage from brushing and styling.

  • Shine and softness

    Glycerin and sodium hyaluronate add lightweight moisture for softer, shinier hair.
