K18 Damage Shield Shampoo

K18 Damage Shield Shampoo is a pH-optimized shampoo made for everyday cleansing — the shampoo half of K18's daily bond-maintenance duo, alongside the Damage Shield Conditioner. It's gentle enough to use every time hair is washed, on every hair type, and it lathers into a soft, cushioned foam that rinses clean without the tight, stripped feeling some clarifying shampoos leave behind. Hair comes out of the shower feeling genuinely clean at the scalp and smooth through the lengths, ready for styling or air-drying.

Massage into wet hair, focusing on the scalp, then rinse thoroughly and follow with Damage Shield Conditioner for the full daily routine. Plant-derived surfactants do the actual cleansing work, lifting dirt and oil without over-stripping, while the shampoo's optimized pH is designed to reduce excess swelling of the hair cuticle during washing — the mechanism behind less frizz, better color retention, and more shine over time. K18PEPTIDE™ is formulated into the wash itself to help reduce the protein loss that naturally happens during cleansing, and the formula is certified microbiome-friendly, so it cleans the scalp without disrupting its natural protective barrier.
