Scalp Care Soothing 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
  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

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

  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 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.

• 4 Menthol
  General function

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

  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.

• 5 Mentha Piperita (Peppermint) Oil
  General function

  Peppermint essential oil, used for scent and the cooling feeling on the scalp.

  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.

  General function

  A chamomile-derived ingredient used for a soothing claim on the scalp.

  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.

  General function

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