How often should a hair mask like this be used?

Once or twice a week is typical; it is a deep-conditioning step, not a daily conditioner.

Does it replace the everyday conditioner?

On the days it is used, yes, it stands in for the regular conditioner. On other days a normal conditioner is used instead.

Key actives

4Dimethicone

A silicone that smooths application and slows surface water loss. It sits alongside this formula's other ingredients as the one doing barrier-support work rather than hydration or brightening.

5Cyclopentasiloxane

A lightweight, fast-evaporating silicone used to improve glide and finish. Its job is finish and application feel rather than an active skin benefit, and it is genuinely on this row's own ingredient list.

23Tocopheryl Acetate

A stable, ester form of vitamin E carried for its antioxidant support. It sits in the formula mainly for that antioxidant role, supporting the other ingredients rather than acting on tone or texture directly.

All products with Tocopheryl Acetate

32Argania Spinosa Kernel Oil

Argan oil, a fatty-acid-rich emollient used for shine and softness. Its job here is feel and finish rather than an active benefit, rounding out the formula the way a plain oil or butter does.

36Camellia Sinensis Leaf Water

Green tea leaf water, used as the formula's water base rather than a plain solvent. It sits in the formula mainly for that antioxidant role, supporting the other ingredients rather than acting on tone or texture directly.

1 of 2

63 of 78 explained

Cetearyl Alcohol fatty alcohol: Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
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.
Dimethicone silicone: Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
Cyclopentasiloxane silicone: Cyclopentasiloxane is a volatile silicone: it spreads a formula thin and smooth then evaporates, leaving no residue. It is the silicone behind a dry, powdery primer finish.
Amodimethicone silicone: A silicone carrying a positive charge, so it is drawn to damaged hair and stays after rinsing. It is a conditioning silicone rather than a slip agent.
Behentrimonium Chloride surfactant: Behentrimonium Chloride is a positively charged conditioning agent. It is the main detangling ingredient in most hair conditioners, and it is not a cleanser.
Propylene Glycol humectant: Propylene Glycol is a small glycol used as a humectant and solvent. It hydrates and helps actives dissolve; newer formulas often swap it for propanediol, which does the same job with a lighter feel.
Hydrogenated Polyisobutene emollient: Hydrogenated Polyisobutene is a stabilised synthetic hydrocarbon used in place of mineral oil. It is an emollient that leaves a smooth, cushioned film.
Stearamidopropyl Dimethylamine surfactant: A conditioning agent that takes on a positive charge in an acidic formula, so it clings to hair. It is used in place of a quaternary conditioner in silicone-free 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.
Behenyl Alcohol fatty alcohol: Behenyl Alcohol is a long-chain fatty alcohol used to thicken and stabilise a cream. It gives a richer, more velvety body than cetyl alcohol.
Isopropyl Alcohol solvent: Isopropyl Alcohol is rubbing alcohol. It dissolves ingredients water cannot, evaporates quickly, and in quantity can leave skin feeling tight.

51 more explained

Beeswax occlusive: Beeswax is the wax bees build comb from. In a formula it thickens the oil phase and forms a breathable, water-resisting film, which is what makes a balm hold its shape.
Behentrimonium Methosulfate emulsifier: A mild cationic conditioning agent built from rapeseed fatty acid. It sits on the surface with a positive charge, which is why it detangles and smooths, and it also helps hold an emulsion together.
Hydroxyethyl Urea humectant: Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.
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.
Tocopheryl Acetate antioxidant: Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
Guar Hydroxypropyltrimonium Chloride film former: Guar gum given a positive charge so it clings to hair and skin through a rinse. It is the plant-derived conditioning polymer in most sulfate-free shampoos.
Olea Europaea (Olive) Fruit Oil emollient: Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
Persea Gratissima (Avocado) Oil emollient: Avocado oil, rich in oleic acid and plant sterols. It is one of the heavier plant oils, which suits dry skin and cleansing balms.
Arachidyl Alcohol fatty alcohol: Arachidyl Alcohol is a long-chain fatty alcohol used as a thickener and emollient, usually alongside behenyl alcohol.
Stearyl Alcohol fatty alcohol: Stearyl Alcohol is a solid fatty alcohol used to thicken and stabilise creams. Like the other fatty alcohols it is an emollient, not a solvent.
Butyrospermum Parkii (Shea) Butter emollient: Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
Argania Spinosa Kernel Oil emollient: Argan Oil is pressed from the argan kernel and is rich in oleic and linoleic acids plus vitamin E. It is a medium-weight emollient that absorbs reasonably fast.
Theobroma Cacao (Cocoa) Seed Butter emollient: Cocoa butter, pressed from the cacao bean. It is firm at room temperature, high in stearic and oleic acid, and used as a rich occlusive emollient.
Bambusa Vulgaris Water plant extract: Bamboo water, the sap or leaf distillate of bamboo, used in place of plain water. It carries silica and minerals and is a dilute base ingredient.
Camellia Sinensis Leaf Water plant extract: Camellia Sinensis Leaf Water is green tea distillate used in place of plain water as a base. It is far more dilute than the extract, so it sets the base rather than supplying the antioxidants.
Hydrolyzed Wheat Protein protein: Hydrolyzed Wheat Protein is wheat protein broken into fragments small enough to dissolve in water. It holds water at the surface and leaves a smooth film, which is why it is as common in hair products as in skincare.
Adansonia Digitata Seed Extract plant extract: Baobab seed extract, from the African tree whose seed oil appears on the same lists. The extract is used as a conditioning, hydrating ingredient.
Octyldodecanol emollient: Octyldodecanol is a branched fatty alcohol used as an emollient and as a solvent for pigments and mineral powders. It thickens slightly and leaves a soft finish.
Sodium PCA humectant: Sodium PCA is one of the substances skin makes for itself to hold water, part of what dermatology calls the natural moisturising factor. Added to a formula it is a strong humectant that suits skin that dehydrates quickly.
Sodium Lactate humectant: Sodium Lactate is the salt of lactic acid and one of the components of skin's own natural moisturising factor. At the levels used here it is a humectant and buffer rather than an exfoliant.
Hydrolyzed Collagen protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
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.
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.
Aspartic Acid amino acid: Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
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.
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.
Pca humectant: PCA is pyrrolidone carboxylic acid, one of the components of the natural moisturising factor skin makes for itself. It holds water at the surface, and its salts do the same job.
Avena Sativa (Oat) Kernel Extract plant extract: Oat Kernel Extract carries beta-glucan and avenanthramides, and it is one of the most reliably tolerated ingredients in skincare. It is used for the look of reddened, itchy-feeling skin.
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.
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.
Hydrolyzed Corn Protein protein: Hydrolyzed Corn Protein is corn protein cut into small soluble pieces. On a label it usually sits with two or three other plant proteins, because each brings a different amino acid balance.
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.
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.
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.
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.
Histidine amino acid: Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
Phenylalanine amino acid: Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
Glycine Soja (Soybean) Seed Extract plant extract: Soybean Seed Extract carries isoflavones, plant sterols and soy proteins. It is used as a conditioning antioxidant extract.
Honey Extract humectant: Honey is a natural humectant loaded with sugars and trace acids. In a formula it holds water at the surface and leaves a soft, cushioned feel.
Vanilla Planifolia Fruit Extract plant extract: Vanilla bean extract. It carries vanillin, the compound its scent comes from, along with polyphenols, so it contributes fragrance as well as extract.
Milk Protein Extract protein: Milk Protein Extract supplies milk proteins and the lactose alongside them. It is used as a conditioning, water-holding ingredient.
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.
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.
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.
Potassium Sorbate preservative: Potassium Sorbate is a preservative that holds off yeast and mould in acidic formulas. It is almost always used with sodium benzoate, because neither covers the whole range of microbes alone.
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.
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.
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.
Fragrance/Parfum 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.

How it works

This is an in-shower or leave-in hair treatment step. TOO COOL FOR SCHOOL's Egg Remedy Hair Pack in its 200ml size centers its formula on dimethicone, a silicone that smooths application and slows surface water loss. Alongside it, the formula carries Cyclopentasiloxane, Tocopheryl Acetate, Argania Spinosa Kernel Oil, rounding out what a single hero ingredient cannot do on its own. Because it rinses off, its job is contact time rather than what is left behind. Work it in, let it sit for a moment on skin or hair, then rinse fully rather than leaving residue behind.

How to use

After shampooing, apply to towel-dried mid-lengths and ends, avoiding the scalp. Leave on for 5 to 15 minutes, then rinse thoroughly. Once or twice a week is typical rather than daily.

Worth knowing

Rinse thoroughly after the processing time, and discontinue if scalp irritation develops.

People with dry, flaky skin are more likely to see a benefit from using vitamin E because it enhances moisturization.
