Guava & Ginger Scalp Exfoliating Pre-Poo Treatment

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 · 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 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.

  Scientific Reports
  • humectant
• 3 Cocamidopropyl Betaine
  General function

  A mild coconut-derived co-cleanser that boosts foam and softens the effect of stronger detergents. It appears in most shampoos, gentle or not.

  Leading ingredient

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

  May suitDry, coarse, or high-porosity hair

  Mild cleansing leaves more surface lubrication in place on hair that dries out quickly.

  May not suitBuild-up-sensitive routines

  The mildest detergents are also the least complete: a routine that deposits films needs something stronger periodically.

  DependsVery dry or highly damaged hair

  Among the mildest detergents in use — it is what baby shampoos are built on — but it is almost always the second detergent in a formula. How much a wash strips is still decided by the primary detergent listed above it.

  • amphoteric cleanser
  • secondary cleanser
  • cleanser
• 4 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 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.

  • gum
  • thickener
  • film former
• 5 Silica · Hydrated Silica
  General function

  A fine mineral powder that absorbs oil and adds grip. It is what makes texture powders and matte pastes feel dry to the touch.

  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 dry powder takes up oil and adds friction between strands, which is most of what root lift in fine hair actually is.

  • powder
  • thickener
  • mineral
• 6 Psidium Guajava Fruit Extract (Guava)
• 7 Zingiber Officinale (Ginger) Root Extract
  General function

  Ginger extract, a traditional scalp botanical used at low levels.

  Supporting ingredient

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

  • botanical extract
• ▾Below about this point, order stops being meaningful — these are typically used at 1% or less.
• 8 Acetic Acid · Acetic Acid (Apple Cider Vinegar)
  General function

  Vinegar acid, used in tiny amounts to bring the formula to an acidic pH so the cuticle lies flat.

  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.

  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.

  • pH adjuster
• 9 Curcuma Longa (Turmeric) Root Oil
• 10 Melaleuca Alternifolia (Tea Tree) Leaf Oil
  General function

  Tea tree essential oil, used in scalp products for its sharp scent and traditional clarifying reputation.

  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

  Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.

  • botanical extract
  • essential oil
  • fragrance
• 11 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
• 12 Menthol
  General function

  Produces the cooling, tingling feeling on the scalp. The sensation is real; it is not evidence that anything else is happening.

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

  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.
