Hydra Source Conditioning Balm

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/eau
  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 Propylene Glycol
  General function

  A small humectant and solvent that keeps formulas stable and helps active ingredients spread.

  Leading ingredient

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

  May suitFine or easily flattened hair

  Light and water-binding rather than oily, so it adds less weight than oils or butters do.

  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.

  PubChem
  • humectant
  • solvent
• 3 Myristyl Alcohol
  General function

  A fatty alcohol used to build texture in creams and add a light smoothing layer.

  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
• 4 Cetrimonium Chloride
  General function

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

  Supporting ingredient

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

  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
• 5 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.

  Role in this product type

  In conditioner, cetearyl alcohol gives the emulsion its creamy structure and helps it spread evenly through the hair. Its emollient layer adds slip and a smoother feel.

  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

  May suit dry, coarse, or high-porosity hair that benefits from added slip and a more substantial conditioning film.

  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

  Consider if hair is fine or easily flattened: a formula built heavily around fatty alcohols can feel richer than a lightweight conditioner.

  BASF
  • fatty alcohol
  • emollient
  • thickener
• 6 Decyl Oleate
  General function

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

  Supporting ingredient

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

  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.

  PubChem
  • light ester
  • emollient
• ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
• 7 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.

  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
  • preservative
• 8 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
• 9 Aloe Barbadensis Leaf Juice
  General function

  Aloe gel, used for light moisture and slip. High in the list it also contributes a little 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

  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.

  • humectant
  • botanical extract
  • gum
• 10 Limonene
  General function

  A citrus-smelling fragrance component that EU rules require to be named separately because some people react to 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

  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.

  PubChem
  • fragrance
  • named fragrance allergen
• 11 Chlorhexidine Dihydrochloride

  General function

• 15 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.
