How it works
Medicube Soycidil Shampoo is a shampoo built for the cleansing step of a hair-care routine. Its ingredient list leads with Melaleuca Alternifolia (Tea Tree) Extract, Ascorbic Acid, and 3-O-Ethyl Ascorbic Acid, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Melaleuca Alternifolia (Tea Tree) Extract does the most work here as a clarity, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the cleansing step of a hair-care routine, it is meant to be used as often as the scalp needs washing rather than swapped freely between steps. Because this is the Korean-market version of the Soycidil Shampoo line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

Key actives
Melaleuca Alternifolia (Tea Tree) ExtractClarity
Melaleuca Alternifolia (Tea Tree) Extract sits in the middle stretch of the ingredient list, a supporting rather than a headline role. It is an ingredient chosen for clarity: a botanical long used in blemish-prone routines for its fresh, clean feel on the skin's surface.
Ascorbic AcidBrightening
Ascorbic Acid sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for brightening: the pure, most active form of vitamin C, included for its brightening reputation though it is also the least stable form, so this formula is best kept away from heat and light.
3-O-Ethyl Ascorbic AcidBrightening
3-O-Ethyl Ascorbic Acid sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for brightening: a stable vitamin C derivative chosen so the brightening benefit holds up over the product's shelf life better than pure ascorbic acid would.
PanthenolComfort
Panthenol sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for comfort: provitamin B5, a humectant and comfort ingredient that softens the finish and helps a formula feel less drying over repeated use.
Copper Tripeptide-1Firming look
Copper Tripeptide-1 sits further down the ingredient list, in a supporting, lower-weighted role. It is an ingredient chosen for firming look: a signal peptide included for its reputation supporting the look of firmer, more resilient skin over consistent use.

What does the Soycidil Shampoo actually contain?
Its ingredient list is led by Melaleuca Alternifolia (Tea Tree) Extract, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the Soycidil Shampoo?
Use this shampoo as the cleansing step of a hair-care routine. To apply, work a coin-sized amount into wet hair and scalp, lather, and rinse thoroughly. Keep it to as often as the scalp needs washing unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the Soycidil Shampoo the same formula sold in Korea, or a US version?
This Soycidil Shampoo is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the Soycidil Shampoo with other actives in my routine?
Yes, as long as it is used in its own step, the cleansing step of a hair-care routine, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the Soycidil Shampoo suited for?
It suits most skin types looking for cleansing step of hair-care routine rather than a single acute problem. It comes in a 490ml format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Payment and security
We accept
How to use
- Use it on wet hair, working the lather into the scalp with the fingertips rather than piling it onto the lengths.
- One wash is usually enough. A second is for days with product or oil built up at the roots.
- Rinse until the water runs clear, then condition the lengths only.
- As often as you wash your hair. Do not scrub with your nails, because the scalp is skin and it scratches.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.

I think it's fair to say I've seen lots of patients use tea tree oil for a variety of skin issues. It's a natural remedy that is known to help.
