Massage into your scalp rather than down the lengths of your hair. Give it a minute, then rinse well.
Part your hair and apply along the part, straight onto your scalp. Press it in with your fingertips. There is nothing to rinse out.
REBECOCO's four-week study measured the shampoo and the tonic used together, so the numbers on this page describe the pair. Use both, every wash.

REBECOCO’s own promise
REBECOCO, Seoul, Korea
Dendropanax Morbifera
Is a small tree native to Korea. Its leaves, stems, and sap have a long history of use for their reported detoxifying and therapeutic properties. It is used in traditional herbal remedies to treat inflammation, and infections. It is known for its active compounds that are rich in flavonoids such as rutin and quercetin, phenolic acids, terpenoids, and antioxidant properties
№ 01–04
REBECOCO starts with concentrated fermented herbs, not water. With 48.2% fermented herb concentrate in our shampoo and 64% in our tonic, you get more botanical ingredients in every drop.
Dendropanax morbifera is traditionally valued for its botanical richness. It contains antioxidant and soothing compounds that help support a healthy scalp and hair environment.
Fermentation transforms the herbs, breaking down complex plant compounds into smaller, more readily available forms. The result is a lightweight tonic that absorbs quickly into the scalp instead of sitting on the surface.
REBECOCO follows its own strict standards. We choose plant-based ingredients, and leave out junk we don't believe belongs. Nothing unnecessary. Just more intentional ingredients.
REBECOCO’s own formula rules
Harmful chemicals
Left out on purpose. REBECOCO builds the formula from ingredients that come from plants.
The EWG safety index
Every ingredient in the formula is checked to adhere to the EWG Safety Index.
“REBECOCO follows its own strict standards. We choose plant-based ingredients, and leave out junk we don't believe belongs. Nothing unnecessary. Just more intentional ingredients.”
REBECOCO's products are nature-based, made with mild natural ingredients instead of the irritating chemicals most products use, to rest your skin and enhance its self-purifying power.
Turn over almost any bottle of shampoo and water is the first thing on the list. Ingredients are printed in order of how much is inside, so most of what you paid for is water.
This is an ingredient list, not a promise. Every plant in the concentrate comes from REBECOCO’s own Golden Drip complex sheet, printed here with the job the brand gives each one.

So we measured it. 4 Weeks, Real Results.
REBECOCO put its scalp-care routine through a human application study conducted at Intertek Korea Testing Services. Over four weeks, the study measured scalp moisture, surface oil, pH, visible flakes, surface temperature, and participants’ reported itchiness and comfort.
Intertek Korea Testing Services ran the tests. The study is REBECOCO’s own. Every number below is theirs.
If your scalp feels oily by evening, or you can see flakes, these are the two numbers to read. Both come from the study above.

Is this a treatment for a scalp condition?
No.
These are cosmetics: they clean, condition, and leave your scalp feeling comfortable. They are not drugs and are not intended to diagnose, treat, cure, or prevent any condition. If you have a diagnosed scalp condition, talk to a dermatologist, a skin doctor.
It is the amount of Golden Drip herb concentrate in each bottle: 48.2% of the shampoo, 64% of the tonic. Most shampoos are mostly purified water. This range is built on the concentrate instead, and the number on the front tells you how much.
The shampoo works on its own as a wash. The tonic is the leave-in step. REBECOCO's four-week study measured the two used together. The set has both for $60, which is $10 less than buying them separately, and it ships free.
It smells herbal rather than perfumed. The formula is amber because it is concentrate, not dye. The shampoo leaves your scalp feeling cool while you rinse, and the tonic dries down clean with no sticky film.
Where we stand
No. These are cosmetics: they clean, condition, and leave your scalp feeling comfortable. They are not drugs and are not intended to diagnose, treat, cure, or prevent any condition. If you have a diagnosed scalp condition, talk to a dermatologist, a skin doctor.
REBECOCO reports that the range has completed sensitivity testing. It is also made to the brand's own list of ingredients it leaves out, and every ingredient is checked against the EWG safety index. If your skin reacts easily, try it on a small patch of skin first, as you would with any new product.
