K18 - Damage Shield pH Protective Shampoo - 473ml

K18 Damage Shield pH Protective Shampoo is a gentle yet effective cleansing shampoo formulated to maintain the optimal pH of the hair and scalp. Its pH-optimized formula helps minimize excessive cuticle swelling during washing, supporting moisture retention while reducing frizz, dullness, and tangling. It is gentle enough for frequent cleansing and safe for colour-treated hair. 

Powered by patented K18PEPTIDE™, the formula helps reduce protein loss to maintain hair strength and integrity. Plant-derived surfactants effectively remove dirt and excess oil, while the microbiome-friendly formula helps preserve the scalp's natural protective barrier. This is the same formula previously known as K18 PEPTIDE PREP™ pH Maintenance Shampoo. 

• Plant-derived surfactants break down dirt and oil with a thorough but gentle lather.
• pH-optimized to prevent the excess cuticle swelling that dulls colour, roughens texture and invites frizz.
• Certified microbiome-friendly: it leaves the scalp's protective microflora in place as it cleans.
• K18PEPTIDE™ reduces protein loss during the wash.
• Colour-safe and gentle enough for every wash.
• In consumer testing, 57% said hair looked healthier and 57% said it didn't feel weighed down.

How to use

• Use every wash: it is built for daily duty.
• Massage in, focusing on the scalp.
• Rinse thoroughly, and repeat if needed.
• Follow with DAMAGE SHIELD™ Protective Conditioner for the daily-defense pairing.

Good to know: this is the shampoo formerly sold as K18 PEPTIDE PREP™ pH Maintenance Shampoo. Same formula, new name.
