Where does this shampoo go in my routine?

In place of your usual shampoo, on hair wet all the way through. Anything thinner than a shampoo goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Copper Tripeptide-1 and not three changes at once.

Does this shampoo contain fragrance?

Yes. The ingredient list names Fragrance. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this shampoo is not the one.

What else is on the list besides Copper Tripeptide-1?

Niacinamide, Asiatic Acid and Madecassoside. The order they are printed in on this shampoo's panel is the order on the box, so you can see where Copper Tripeptide-1 sits relative to them. Further down the same panel: Madecassic Acid, Asiaticoside and Salicylic Acid.

How it works

The Doopi Lab Core Peptide Volume Shampoo is a 500g shampoo, used in place of your usual shampoo, on hair wet all the way through. The peptide it is built around is Copper Tripeptide-1, named fifty-second on its own ingredient list. The same list carries Niacinamide, Asiatic Acid and Madecassoside, so the peptide is not the only thing on it worth naming. How much of the Copper Tripeptide-1 stays on the skin, and for how long, is decided by the shampoo format rather than by the list alone. Dr.G sells this Copper Tripeptide-1 shampoo in Korea, and this is that version.

How to use

Massage into wet hair and scalp, lather, then rinse thoroughly. Follow with conditioner.

1 of 3

45 of 55 explained

Purified water solvent: Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
disodium laureth sulfosuccinate surfactant: A sulfosuccinate surfactant: milder than a sulfate, with more foam than an amino-acid one. It is often used to soften a sulfate-based cleanser.
coco-betaine surfactant: Coco-Betaine is a coconut-derived secondary surfactant used to build foam and make a cleanser milder.
sodium C14-16 olefin sulfonate surfactant: A strong anionic surfactant that foams heavily. It is a sulfate alternative in name but not in strength, and it is more common in shampoos than in facial cleansers.
sodium chloride thickener: Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
sodium lauroyl methyl isethionate surfactant: Sodium Lauroyl Methyl Isethionate is a mild cleanser that makes a dense, creamy foam. It is one of the gentlest surfactants that still lathers properly.
glycerin humectant: Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
fragrance fragrance: Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
potassium cocoyl glycinate surfactant: Potassium Cocoyl Glycinate is a coconut-and-glycine surfactant used in low-pH cleansers. It foams well and rinses without the squeaky tightness a soap leaves.
citric acid pH adjuster: Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
phenethyl alcohol preservative booster: Phenethyl Alcohol is an aromatic alcohol with a faint rose scent. It works as a preservative booster and a light solvent, and it is common in formulas built without traditional preservatives.
salicylic acid exfoliant: Salicylic Acid is a BHA, and the only common exfoliant that is oil soluble, so it can work inside a pore rather than only on the surface. It loosens the dead cells that block pores and is used for the look of congested, oily skin.

33 more explained

dexpanthenol humectant: Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
glycol distearate emollient: A wax-like ester that thickens a cleanser and gives it a pearly opacity. It also leaves a conditioned feel behind after rinsing.
hexylene glycol solvent: Hexylene Glycol is a solvent and light humectant. It keeps ingredients that resist water in solution and thins a formula so it spreads evenly.
caprylyl glycol preservative booster: Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
glycol stearate emulsifier: Glycol Stearate is a mild emulsifier and thickener. It also gives a cleanser or lotion its opaque, pearly look.
niacinamide active: Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
trihydroxystearin thickener: A castor-derived wax used to thicken oils and stop pigments settling. It builds structure in an anhydrous formula without making it hard.
disodium EDTA chelator: EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
ethylhexylglycerin preservative booster: Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
butylene glycol humectant: Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
1,2-hexanediol humectant: 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
hydrogenated lecithin emulsifier: Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
caprylic/capric triglyceride emollient: Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
Sodium Hyaluronate humectant: Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it.
Ceramide NP barrier lipid: Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
Glycine amino acid: Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
Asiatic Acid active: Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
Lysine amino acid: Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
Madecassoside active: Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
Serine amino acid: Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
Glycoprotein protein: Glycoproteins are proteins carrying sugar chains, usually supplied by a ferment. They hold water and leave a conditioning film.
Hydrolyzed Rice Protein protein: Hydrolyzed Rice Protein is rice protein broken into small fragments. It is a humectant and film former that leaves a soft, smooth finish.
Hydrolyzed Keratin protein: Hydrolyzed Keratin is keratin, the protein hair and nails are built from, cut into fragments small enough to dissolve. In a formula it is a humectant and a smoothing film former.
Hydrolyzed Soy Protein protein: Hydrolyzed Soy Protein is soy protein cut into water-soluble fragments. It conditions the surface and holds water, and it is one of the most used plant proteins in cosmetics.
Madecassic Acid active: Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
Arginine amino acid: Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
Centella Asiatica Extract plant extract: Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
Cysteine amino acid: Cysteine is a sulphur-bearing amino acid used as a humectant and antioxidant. It is one of the three building blocks of glutathione.
Asiaticoside active: Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
Copper Tripeptide-1 peptide: Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
SH-Oligopeptide-2 peptide: sh-Oligopeptide-2 is a second fermentation-produced peptide, used alongside sh-oligopeptide-1 for the look of firmness.
SH-Polypeptide-1 peptide: sh-Polypeptide-1 is a longer fermentation-produced peptide. It is used in formulas built around the look of resilience and recovery.
SH-Polypeptide-9 peptide: sh-Polypeptide-9 is another fermentation-produced peptide used for the look of firmness, usually as part of a blend.

Worth knowing

Patch test this shampoo on a small area and wait a day before using it more widely, especially with Copper Tripeptide-1 on the list.
This list names Fragrance, so skip it if fragrance components are something you avoid.
Citric Acid and Salicylic Acid on this list makes this shampoo an exfoliating step, so do not stack it with another one on the same night.
