How pre-ordering works
Step 01
Pick single products or the full four-step system. You pay at checkout, which locks in your pre-order price and holds your unit from the first run.
Step 02
Production starts as soon as reservations are in. We make exactly what is reserved — nothing sits on a shelf for months.
Step 03
Your parcel leaves our studio, we email you tracking, and the ritual card goes in the box.
Every pre-order comes from the first run. When the 2,000 are gone, the next run ships in the new year.

CoolRoots treats the scalp the way skincare treats the face — loosen buildup, exfoliate gently, cleanse, then nourish. Four steps, in that order, every time.
Oat to calm, sweet almond oil to soften, tea tree to clear buildup and rosemary to support the scalp over time. Nothing in the formula that isn't earning its place.
Built for dry, sensitive scalps and safe to use as often as your routine needs — cruelty-free, and gentle enough for colour-treated hair.
The Comparison
See how the CoolRoots system stacks up against the three things sensitive scalps reach for first. Pick a comparison below.
Scalp care that works from the root out.
CoolRoots works at the scalp itself — clearing buildup and supporting the skin and biome where healthy hair begins.
Botanical actives gently clear buildup and help maintain the scalp’s natural balance — the foundation of healthy hair.
Colloidal oat and sweet almond rebuild the barrier as they clean, so hair never feels tight or squeaky.
Pre-cleanse, cleanse, treat and protect — every stage of a healthy scalp routine in one kit.
If your scalp is not calmer in 30 days, get a full refund. Zero risk.
Inside every bottle
Free from methyl parabens. No filler chemistry. Just three plant-powered actives working together to calm, clean and protect your scalp from the root out.

The reason marmee never leaves your scalp tight. Colloidal oat lays down a soothing layer that calms redness and itch while rebuilding the skin barrier the flakes broke down — the actives sensitive, reactive scalps trust.

Lightweight almond oil sinks into the follicle to soften buildup and replace the moisture medicated shampoos strip away. Rich in vitamin E and fatty acids, it conditions at the root with no greasy film.

Naturally antimicrobial, rosemary keeps the scalp clean between washes and stimulates circulation at the follicle — the action linked to fuller-looking hair at the part. Its fresh, herbal scent replaces synthetic fragrance.
