Description

K18 Damage Shield pH Protective Shampoo is a gentle daily cleanser that helps defend hair from damage.

This shampoo works with a pH-optimised formula to deeply clean away product build-up, excess oil, and pollution while respecting your scalp and colour. The gel-like texture lathers into a soft, cushiony foam that rinses clean without leaving hair feeling stripped or squeaky.

Hair feels light, smoother, and easier to brush, with a soft, healthy-looking shine. There’s a fresh, subtle scent that doesn’t overpower your other products.

It’s ideal for colour-treated, chemically processed, or frequently styled hair, and gentle enough for everyday use. Reach for it whenever hair feels weighed down, dull, or stressed from heat styling and environmental exposure.

Directions

How To Use K18 Damage Shield pH Protective Shampoo

Massage gently into scalp, working through lengths to ends.
Add a little water to build a soft lather if needed.
Rinse thoroughly until water runs clear.
Repeat if hair has heavy build-up or excess oil.
Follow with your preferred conditioner or treatment.
