Brass Off All-In-One Toning Leave In Spray

In the US, ingredients above 1% are listed from most to least. Below 1% they can appear in any order. Each note keeps three things apart: what the ingredient generally does, its role in this type of product, and what its position can tell you.

• 1 Water · Aqua/Water
  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 Cetearyl Alcohol
  General function

  A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.

  Leading ingredient

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

  May suitDry, coarse, or high-porosity hair

  The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.

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

  Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

  DependsFine or easily flattened hair

  Near the top of a conditioner it is doing most of the conditioning, and most of the weighting, at the same time.

  PubChem
  • fatty alcohol
  • emollient
  • thickener
• 3 Phenoxyethanol
  General function

  The most common modern preservative; it keeps the product free of bacteria and mould. It sits well below 1% of the formula.

  Leading ingredient

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

• ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
• 4 Fragrance · Parfum/Fragrance
  General function

  An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

  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 not suitFragrance-sensitive routines

  Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

  • fragrance
  • declared fragrance
• 5 Amodimethicone
  General function

  A silicone modified to stick where hair is damaged, so it smooths selectively instead of coating everything. It resists rinsing more than plain dimethicone.

  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 suitClimate-sensitive or frizz-prone hair

  A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

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

  Amino-functional silicone carries a positive charge, so it binds where the cuticle is worn rather than coating evenly. Damaged areas get most of it.

  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.

  International Journal of Trichology
  • silicone
  • conditioning agent
  • film former
• 6 Hydroxypropyl Starch Phosphate
  General function

  A modified starch that thickens and leaves a light, powdery film — often used for body in curl products.

  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

  Adds grip and body with no oil attached, which is what lifts fine hair at the root instead of weighing it down.

  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.

  DependsMaximum-hold styling

  Starch gives texture and grip rather than a set film; firm hold usually needs a polymer alongside it.

  • starch
  • thickener
  • film former
• 7 Cetrimonium Chloride
  General function

  A quick-acting conditioning agent that reduces static and combing force. It also helps keep the formula stable.

  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

  The C16 quat binds mostly by charge rather than by chain, so it deposits measurably less than the C22 ones. Less deposit is less conditioning and also less weight, which is usually the trade fine hair wants.

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

  A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

  DependsBuild-up-sensitive routines

  Substantive by design. A routine with no detergent wash gives it nothing to leave with.

  International Journal of Cosmetic Science
  • conditioning agent
  • cleanser
• 8 Ceteareth-20
  General function

  An emulsifier that holds oil and water together in a conditioner or cream.

  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.

  • emulsifier
• 9 Ethylhexylglycerin
  General function

  A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.

  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

  Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

• 10 C11-15 Pareth-7

  • emulsifier
  • solubilizer
• 12 Glycerin
  General function

  Glycerin, also called glycerol, attracts moisture and mixes completely with water.

  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 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 soft floral fragrance component listed separately as a recognised allergen.

  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 not suitFragrance-sensitive routines

  One of the 26 scent components the EU requires to be named individually above a threshold. It is named because it is a known contact allergen, not because it is unusual.

• 17 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.
