Rosemary Mint Hair & Scalp Serum

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

• 1 Water · Water (Aqua)
  General function

  The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

  Leading ingredient

  Listed in the first three ingredients, it is likely a structural part of this formula.

  • solvent
• 2 Polysorbate 20
  General function

  Keeps fragrance and oils dissolved in a watery formula so it stays clear.

  Leading ingredient

  Listed in the first three ingredients, it is likely a structural part of this formula.

  • solubilizer
  • emulsifier
• 3 Glycerin
  General function

  A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.

  Leading ingredient

  Listed in the first three ingredients, it is likely a structural part of this formula.

  May suitDry, coarse, or high-porosity hair

  High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.

  May suitVery dry or highly damaged hair

  Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.

  DependsClimate-sensitive or frizz-prone hair

  Water moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.

  General function

  A light humectant and carrier that helps extracts dissolve.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitFine or easily flattened hair

  Light and water-binding rather than oily, so it hydrates without contributing weight.

  May suitVery dry or highly damaged hair

  A small water-binding solvent. It holds moisture and helps the rest of the formula spread evenly over the strand.

  DependsClimate-sensitive or frizz-prone hair

  A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

  May suitFrizz-prone, damaged, or high-friction hair

  Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.

  PubChem
  • vitamin
  • conditioning agent
• 11 Xanthan Gum
  General function

  A fermented sugar gum that thickens water-based formulas and adds soft, natural hold.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitCurls or waves needing flexible hold

  A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.

  May suitFrizz-prone, damaged, or high-friction hair

  A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.

  May not suitMaximum-hold styling

  Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.

  General function

  A fatty ester. Esters give slip and a smooth after-feel; lighter ones read dry and silky, heavier ones read rich.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitFine or easily flattened hair

  A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

  May suitFrizz-prone, damaged, or high-friction hair

  Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

  May suitFine or easily flattened hair

  It hydrates without adding oil or a film, which is the combination fine hair usually needs.

  May suitVery dry or highly damaged hair

  A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.

  DependsClimate-sensitive or frizz-prone hair

  A humectant follows the air: it holds water in humid conditions and can give it up in very dry ones. Climate decides what it does more than the label does.

  • vitamin

• 18 Maltodextrin
  General function

  A starch fragment that soaks up oil and water, which is what puts it in dry shampoos. It also carries spray-dried plant extracts and leaves a light film.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitFine or easily flattened hair

  Takes up oil at the root, which is where fine hair goes flat first.

  May suitMaximum-hold styling

  Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

  DependsCurls or waves needing flexible hold

  How rigid the finish is depends on which polymer it is and what the formula pairs with it, not on there being one.

  • absorbent
  • film former
  • binder
• 19 Citric Acid
  General function

  Used to bring the product to a slightly acidic pH, which helps the cuticle lie flat. It is almost always near the end of the list.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitBuild-up-sensitive routines

  Holds hard-water minerals in solution so they rinse away instead of depositing on the hair.

  May suitFrizz-prone, damaged, or high-friction hair

  The acid side of pH adjustment, and the reason it matters is measured: alkaline formulas raise the fibre's surface negative charge, increase friction between strands and lift the scales, while lower-pH ones do the reverse.

  May suitGray, silver, or brass-prone hair

  Where a warm cast comes from water minerals rather than from the hair itself, holding those metals in solution is what removes it.

  May suitCurls or waves needing flexible hold

  Gums thicken and set soft, which gives definition that bends rather than a rigid cast.

  May suitFine or easily flattened hair

  Hydration with no oil attached, so it adds very little weight even high on a list.

  May suitVery dry or highly damaged hair

  Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.

  Amino acids are the smallest protein fraction and bind water as well, so they add far less stiffness than a hydrolysed protein does.

  The lightest option in the protein family, but still protein — worth watching if protein reliably stiffens your hair.

  May suitBuild-up-sensitive routines

  Binds the calcium and magnesium in hard water, which is what stops mineral deposits accumulating on the strand wash after wash.

  May suitGray, silver, or brass-prone hair

  Copper and iron carried in tap water deposit on the strand and read as a dull, warm cast on gray or light hair. A chelator holds those metals in solution so the wash carries them off.

  DependsFrizz-prone, damaged, or high-friction hair

  pH adjusters are how a formula is brought to a chosen acidity, and an acidic formula keeps the cuticle lying flatter than an alkaline one. Which way this one moves the pH depends on the formula, and the finished pH is not on the label.

• 35 Hydrolyzed Lupine Protein
  General function

  A protein broken into fragments small enough to cling to the hair. It fills gaps on damaged strands and firms the feel for a few washes; too much reads as stiff.

  Estimated lower-concentration zone

  It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

  May suitFrizz-prone, damaged, or high-friction hair

  Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.

  May suitMaximum-hold styling

  Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

  May suitVery dry or highly damaged hair

  Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
