Who it's for
Made for

- Coily hair
- Oily scalp
- Balanced scalp
- Dry scalp
- Flaky or itchy scalp
- Dryness
- Frizz

Why pick it
- 7 key ingredients, each linked to its study
- No fragrance, essential oils, MI/MCI or formaldehyde releasers
- How often
- Every wash
- You notice it
- From the first wash
Why it works
Cetearyl alcohol (a waxy fatty alcohol, not a drying one)
Builds the creamy gel that carries the conditioner. Lab work found gel strength depends on the conditioner-to-fatty-alcohol ratio.
Camellia seed oil
A Procter and Gamble study found it enters the lipid-rich cement between hair cells and raised single-fiber fatigue strength.
How to use it
- 1After conditioner, on soaking-wet hair, work a small amount through mid-lengths and ends.
- 2Style as usual, with the Curl Cream if you use it.

What we leave out, and why
- FragranceA leading cause of contact allergy
- Essential oilsNatural, but a known skin allergen
- MI/MCIPreservatives behind an allergy rise in Europe
- Formaldehyde releasersSlowly release formaldehyde, a skin allergen
- Zinc pyrithioneBanned in EU cosmetics since 2022

Frequently asked
How much do I use?
A small amount on soaking-wet mid-lengths and ends, worked in with your fingers. Use less if your hair feels heavy.
Do I still need the conditioner?
Yes. The conditioner is rinsed out and does the main conditioning. The leave-in cream stays in for extra slip and softness.
Can I layer it under the Curl Cream and Curl Gel?
Yes. Put the leave-in cream on first, then the Curl Cream, then the gel if you use one.
Will it make fine hair flat?
It can, because it is richer. Fine or low-density hair does better with the Light Leave-in Mist.
Can I use it every wash?
Yes. It is made for every wash, on soaking-wet hair.

Key studies behind this product
EU sets caps on conditioning agents in hair products
The EU caps behentrimonium chloride at 5.0% in rinse-off and 3.0% in leave-on hair products, and cetrimonium chloride at 2.5% rinse-off and 1.0% leave-on. Combined amounts must stay under the cap because mixtures can irritate.
