Pro-V Curl Perfection Conditioner

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
  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 Cetyl Alcohol
  General function

  A fatty alcohol used to thicken creams and add slip. It softens rather than dries.

  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 Stearamidopropyl Dimethylamine
  General function

  A gentle conditioning agent activated by the acid in the formula. It smooths the cuticle without much build-up.

  Leading ingredient

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

  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.

  May suitVery dry or highly damaged hair

  The class that does the detangling in a conditioner. It deposits lubrication where the cuticle is worn.

  DependsBuild-up-sensitive routines

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

  PubChem
  • conditioning agent
• 4 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.

  Supporting ingredient

  Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.

  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.

  Scientific Reports
  • humectant
• 5 Stearyl Alcohol
  General function

  A fatty alcohol that thickens conditioners and helps them coat the hair evenly.

• ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
• 6 Glutamic Acid
  General function

  An amino acid used for moisture binding and to bring the formula to an acidic pH.

  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 suitVery dry or highly damaged hair

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

  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.

  DependsProtein-sensitive hair

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

  PubChem
  • amino acid
  • pH adjuster
• 7 Bis-Aminopropyl Dimethicone
  General function

  An amino-modified silicone that binds to damaged spots for smoothing that survives rinsing.

  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.

  • silicone
  • conditioning agent
  • film former
• 8 Sodium Chloride
  General function

  Table salt. In shampoo it is used to thicken the liquid, not to treat the hair.

  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.

  PubChem
  • salt
  • thickener
• 9 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
• 10 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.

• 12 Disodium EDTA
  General function

  Grabs metal ions from hard water so they cannot dull the hair or destabilise the formula.

  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

  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.

  PubChem
  • hard-water chelator
• 13 Phenoxyethanol
  • preservative
• 14 Histidine
  General function

  One of the amino acids that make up hair protein, added for moisture binding.

  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 suitVery dry or highly damaged hair

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

  DependsProtein-sensitive hair

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

  PubChem
  • amino acid
• 15 Panthenol
  General function

  Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.

  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

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

  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.

  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.

  PubChem
  • humectant
  • conditioning agent
  • vitamin
• 16 Panthenyl Ethyl Ether
  General function

  A panthenol derivative used for the same softness and shine effect, with a lighter feel.

  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

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

  May suitVery dry or highly damaged hair

  Humectants bind water into the strand, and water — not oil — is what makes dry hair flexible instead of brittle.

  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.
