Does this product contain added fragrance?

Yes. The ingredient list for Dr.Groot AQUA HAIR LINE BOOSTER SHOT 15ml includes Fragrance. That is the label name for an added scent blend, whose individual components are not itemised beyond any allergens the label declares separately. The full list is printed in the Ingredients section of this page.

Are any declarable fragrance allergens listed?

Yes. Limonene, Linalool, Citronellol, Geraniol, Hydroxycitronellal, Citral, Hexyl Cinnamal and Coumarin appear on the ingredient list for Dr.Groot AQUA HAIR LINE BOOSTER SHOT 15ml. These belong to the 26 fragrance components that EU cosmetic labelling requires to be named individually rather than folded into a fragrance entry.

Does this product contain denatured or SD alcohol?

Yes. The ingredient list for Dr.Groot AQUA HAIR LINE BOOSTER SHOT 15ml includes Alcohol Denat. That is the solvent form of alcohol, and it is a different ingredient from the fatty alcohols such as cetyl and cetearyl alcohol that many formulas use as emollients.

How to use

Use the HAIR LINE BOOSTER SHOT after shampooing, on hair towelled to damp rather than dripping.
Twist the button at the bottom of the container to open, then press the button to release the product. Apply to the clean, dry scalp and hairline, gently massaging as directed. Turn the button in the opposite direction to lock the container.
Shampoo first, this second. Leave it for the time the pack gives, then rinse.
Once or twice a week. Do not work it into the roots; a treatment weighs down the one part of the hair that does not need it.

1 of 3

75 of 80 explained

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.
Alcohol Denat solvent: Alcohol Denat. is ethanol with a bitter additive that makes it undrinkable, which is a tax rule rather than a formulation choice. It behaves like alcohol: a fast-evaporating solvent that gives a weightless finish and can feel drying at higher levels.
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.
Dipropylene Glycol humectant: Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
Diethoxyethyl Succinate solvent: Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
Dexpanthenol (Panthenol) 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.
PEG-40 Hydrogenated Castor Oil emulsifier: PEG-40 Hydrogenated Castor Oil is the most used solubiliser in clear toners and micellar waters. It holds small amounts of oil and fragrance in solution without turning the formula cloudy.
Adenosine active: Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
Menthol active: Menthol is the cooling compound in mint. It acts on the nerve receptor that also answers to cold, which is why skin feels cool without any change in temperature.
Gluconolactone exfoliant: Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
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.
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.

63 more explained

Hydroxyethylcellulose thickener: Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
Sodium Citrate pH adjuster: Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
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.
Piroctone Olamine preservative: Piroctone Olamine is an antifungal preservative. It is used mainly in scalp and hair products rather than in facial skincare.
Betaine humectant: Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
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.
Trehalose humectant: Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
Rosmarinus Officinalis (Rosemary) Leaf Extract plant extract: Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
Biotin vitamin: Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
Ferulic Acid antioxidant: Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
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.
Lactococcus Ferment Lysate ferment: Lactococcus Ferment Lysate is a lactic-culture ferment with the bacterial cells broken open, so their contents are in the formula too. It is used as a conditioning ferment in barrier-focused products.
Inulin polysaccharide: Inulin is a plant fructan, most often from chicory root. It holds water and, in a formula, feeds the beneficial bacteria on the surface.
Tocopherol antioxidant: Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
Glycine Soja (Soybean) Oil emollient: Soybean Oil is a linoleic-rich plant oil used as an emollient. It also carries soy phytosterols and vitamin E.
Disodium Phosphate pH adjuster: Sodium Phosphate is a buffer salt. It holds a formula at a steady pH so its actives stay in the form they work in.
Caffeine active: Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin.
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.
Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
Scutellaria Baicalensis Root Extract plant extract: Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
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.
Yeast Extract ferment: The soluble contents of yeast cells, carrying amino acids, peptides, sugars and B vitamins. It is used as a conditioning ingredient and as a source of beta glucan.
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.
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.
Houttuynia Cordata Extract plant extract: Houttuynia Cordata is heartleaf, and it is one of the two or three anchor plants of Korean calming skincare. Its extract carries quercitrin and other flavonoids and is used for the look of redness and blemish-prone skin.
Sodium Benzoate preservative: Sodium Benzoate is a mild preservative that works only in acidic formulas. It is usually paired with potassium sorbate, and the pair is the standard choice where a brand wants no phenoxyethanol.
Sodium Ascorbate vitamin: The sodium salt of vitamin C. It is less acidic than pure ascorbic acid and dissolves readily in water, though like ascorbic acid it still oxidises once in solution.
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.
Glutamic Acid amino acid: Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
Centella Asiatica Leaf 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.
Saccharomyces Cerevisiae Extract ferment: An extract of brewer's yeast, the same organism used to make bread and beer. It supplies amino acids, sugars and beta-glucan and is used as a conditioning ferment.
Eucalyptus Globulus Leaf Extract plant extract: Eucalyptus leaf extract, the water-based extract rather than the essential oil. It carries tannins and flavonoids with only a trace of the aroma.
Aspartic Acid amino acid: Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
Leucine amino acid: Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
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.
Phenoxyethanol preservative: Phenoxyethanol is the most widely used cosmetic preservative outside the paraben family. It keeps a water-containing formula from growing bacteria and mould, and is capped at one percent in most markets, so it always sits low on a list.
Retinol active: Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.
Alanine amino acid: Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
Lysine amino acid: Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
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.
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.
Tyrosine amino acid: Tyrosine is an amino acid used as a conditioning humectant in amino acid complexes.
Phenylalanine amino acid: Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
Proline amino acid: Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
Threonine amino acid: Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
Valine amino acid: Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
Isoleucine amino acid: Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
Histidine amino acid: Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
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.
Methionine amino acid: Methionine is a sulphur-bearing essential amino acid used as a humectant and mild antioxidant.
Chamaecyparis Obtusa Leaf Extract plant extract: Chamaecyparis Obtusa is hinoki cypress. Its leaf extract carries aromatic plant compounds and is used in Korean formulas aimed at oily, congested skin.
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.
Bifida Ferment Lysate ferment: Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
Lactobacillus Ferment Lysate ferment: Lactobacillus Ferment Lysate is the ferment with the bacterial cells broken open, so their contents are in the formula too. It is a conditioning ferment used in barrier-focused products.
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.
Limonene fragrance component: Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
Linalool fragrance component: Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.
Citronellol fragrance component: Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
Geraniol fragrance component: Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
Hydroxycitronellal fragrance component: Hydroxycitronellal is a soft lily-of-the-valley aromatic. It is one of the 26 declarable fragrance components.
Citral fragrance component: Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.
Hexyl Cinnamal fragrance component: Hexyl Cinnamal is a jasmine-like aromatic. It is one of the 26 fragrance components EU labelling requires to be named individually.
