The everyday shampoo in the K18 range — the one you use for every wash, with the Detox Shampoo brought in weekly and the mask as the repair step. It is built around pH: washing at the wrong pH swells the cuticle open, and an open cuticle is where frizz, dullness and colour loss start.

The actives

  • K18PEPTIDE (sh-oligopeptide-78) — the brand's patented peptide, included at wash level.
  • pH-optimised surfactant blend — cleanses without letting the cuticle swell more than it needs to.
  • Panthenol and glycerin — humectants that hold moisture in through the wash.
  • Sodium phytate — a chelator that helps stop water minerals depositing on the strand.

How to use it

Massage into wet hair with the focus on the scalp, rinse thoroughly, repeat if needed. Gentle enough for every wash. Follow with K18 Damage Shield Conditioner.

Who it's for

Colour-treated hair, hair prone to frizz, and anyone washing often who needs a shampoo that will not undo their colour or their treatment. It is a maintenance product — the repair work is the mask's job.

Massage into wet hair, focusing on the scalp. Rinse thoroughly and repeat if needed. Suitable for every wash. For optimal results, follow with K18 Damage Shield Protective Conditioner.

Frequently Asked Questions

Q. How does pH-balanced shampoo benefit the hair?

A. A pH-balanced shampoo helps keep the hair cuticle smooth and closed, which can reduce frizz, improve shine and protect colour. It also supports scalp health by maintaining the natural protective barrier during cleansing.

Q. How does pH optimisation protect hair during washing?

A. K18 Damage Shield pH Shampoo features a pH-optimised formula that helps maintain the hair cuticle’s natural balance during washing. By preventing excess cuticle swelling, this protects against frizz, dullness and potential breakage while preserving colour and smoothness.

Q. Is this shampoo gentle on the scalp and suitable for frequent use?

A. Yes. The DHA-protective shampoo is microbiome-friendly and formulated to cleanse without disrupting the scalp’s natural protective barrier. Its gentle cleansing action makes it suitable for daily or frequent washing while maintaining scalp health.
