Turmeric Guava Thick and Smooth Hair Food Serum

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 (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 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.

  Leading ingredient

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

  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
• 3 Propanediol
  General function

  A corn-derived humectant and solvent, often chosen as a lighter-feeling alternative to propylene glycol.

  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
• 4 Dextran
  General function

  A polysaccharide polymer used as a thickener and binder in serums and scalp treatments, helping increase viscosity and hold ingredients together.

  Supporting ingredient

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

  • polymer
  • thickener
  • binder
• 5 Acetyl Tetrapeptide-3
  General function

  A small synthetic peptide included in scalp serums and scalp treatments marketed for fuller-looking hair, often as part of a branded complex alongside red clover extract. It is a formulated active rather than a cleansing or conditioning agent.

  Supporting ingredient

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

  • active
  • protein
• 6 Trifolium Pratense Flower · Trifolium Pratense (Clover) Flower
• 7 Xanthan Gum
  General function

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

  Supporting ingredient

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

  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 helps flyaways lie down.

  May not suitMaximum-hold styling

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

  • gum
  • thickener
  • film former
• ▾Below about here, the order stops meaning much. These are usually used at 1% or less.
• 8 Sodium Benzoate
  General function

  A food-grade preservative that works only in acidic formulas, which is why it usually appears alongside citric acid.

  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
• 9 Potassium Sorbate
  • preservative
• 10 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.

  PubChem
  • preservative
  • emollient
• 11 Sodium Hyaluronate
  General function

  A large water-binding molecule that sits on the surface holding moisture.

  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

  A humectant moves water in whichever direction the air allows: it holds moisture in humid conditions and can pull it back out of hair in very dry ones.

  • humectant
• 12 Serenoa Serrulata Fruit Extract · Serenoa Serrulata (Saw Palmetto) Fruit Extract
  • botanical extract
• 13 Rosmarinus Officinalis (Rosemary) Leaf Extract
  • botanical extract
  • antioxidant
• 14 Arginine
  General function

  An amino acid that holds water and carries a positive charge, so it is drawn to damaged spots on the strand.

  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.

  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.

  DependsProtein-sensitive hair

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

  PubChem
  • amino acid
  • humectant
• 15 Lactic Acid
  General function

  An acid used to set pH and, in scalp products, to loosen flakes.

  Estimated lower-concentration zone

  General function
