Full Formula
Twelve ingredients, each doing a specific job. Tap any one to see what it does.
Penetrates the hair shaft to help reduce protein loss during washing and styling, keeping strands stronger over time.
Seals in moisture and softens hair without weighing it down or leaving residue.
A gentle mineral clay that absorbs excess oil at the scalp and root, adding natural texture and lift.
Locks in moisture and gives the clay long-lasting, reworkable hold through the day.
A stronger mineral clay that provides firm, flexible hold and a clean matte finish.
A natural plant starch that keeps the finish matte, never greasy.
Fills in damaged areas along the hair shaft, plumping and strengthening each strand from the outside in.
Studied for its ability to penetrate the scalp and stimulate hair follicle activity.
Matched a leading topical hair treatment for hair count in a 6-month clinical trial.
Adds a subtle, grounded fragrance with a long history of traditional use for calming the scalp.
Protects the formula's oils from going rancid over time and adds a light natural finish.
Gives a cooling, stimulating feel on the scalp with each application.
Ingredients Studied for Hair Growth & Thickness
Four ingredients in this formula have real clinical research behind them for growth, density, or strand strength — here's the actual science, not just a claim.
Rosemary Oil vs. 2% Minoxidil
In a six-month clinical trial, researchers compared topical rosemary oil directly against 2% minoxidil. Both groups saw a significant increase in hair count by the end of the study, with no meaningful difference between the two treatments. Differences weren't visible until after the three-month mark, which is why consistent daily use matters.

Nine Clinical Trials on Topical Caffeine
A 2024 systematic review examined clinical trials testing topical caffeine against hair loss, covering nearly 700 participants across nine separate trials. The review found consistent support for caffeine's ability to penetrate the hair follicle and stimulate cell activity linked to hair growth.

Early Research: Peppermint Oil and Hair Growth
In a controlled study using mice, topical peppermint oil was compared against saline, jojoba oil, and minoxidil. The peppermint oil group showed the strongest results across several measures, outperforming the minoxidil group on some. This research has only been conducted in animals so far — no published human clinical trials exist yet.

Repairing the Strand, Not the Root
Hair is roughly 90% keratin, and daily wear, heat, and UV exposure gradually break that protein down. Hydrolyzed keratin is small enough to penetrate the hair shaft rather than sitting on the surface. A peer-reviewed study found hair treated with hydrolyzed keratin maintained its tensile strength after UV exposure, while untreated hair lost over 14% of its strength.
Performance and Mechanism of Hydrolyzed Keratin for Hair Photoaging Prevention
Unlike the ingredients above, hydrolyzed keratin works on the existing strand, not the follicle or growth cycle.
Three Steps, Every Style
Scoop a dime-size amount
Warm it between your palms until soft and matte.
Apply to damp hair, at the roots
Damp hair helps the clay spread evenly for the best hold.
Shape and go
Reworkable all day — no need to reapply to reset your style.
Not Just Another Clay
What Customers Notice First
Finally a clay that doesn't leave my hair looking wet or greasy. Matte finish all day, and it doesn't crumble like the last one I tried.
I liked that they actually link to the studies instead of just saying "clinically proven." My hairline looks fuller after a couple months of daily use too.
Good hold without the crunch you get from gel. Took a couple weeks to find the right amount to use, but once I did it's been my daily go-to.
The cedarwood scent is subtle, not overpowering like some clays. Genuinely surprised by how clean the ingredient list is compared to what I was using before.
My scalp feels noticeably less oily by the end of the day. Didn't expect a styling product to also feel like it's doing something for my hair.
Reworkable through the whole day is not an exaggeration — I've run my fingers back through it at 6pm and it still holds. Small jar goes a long way.
Ordered because of the ingredient breakdown on the site, honestly. Stayed because it just works better than the drugstore clay I'd used for years.
