got a question?

No, the DAMAGE SHIELD pH protective shampoo formula is the same as the PEPTIDE PREP™ pH maintenance shampoo — only the name has changed. You’re still getting the formulation you know and love.

The DAMAGE SHIELD pH protective shampoo promotes healthier hair and scalp after just one wash. Its optimised pH helps maintain the hair cuticle, preventing excess water absorption that can lead to damage, dullness, frizz, and tangling. This shampoo preserves colour, strengthens hair, reduces frizz, smooths strands, and makes styling easier with less tangling.

Lightweight yet moisturising, it nourishes hair without weighing it down and supports a healthy scalp by preserving the scalp microbiome for a gentler cleanse. When paired with the DAMAGE SHIELD protective conditioner, these formulas work together to shield your healthiest hair from daily damage.

This pH-balanced formula is gentle enough to use every time you cleanse, delivering healthier hair and scalp after just one wash.

You need both shampoos for the most effective clean while maintaining hair and scalp health. The detox shampoo is designed for less frequent, heavy-duty cleansing, while the DAMAGE SHIELD pH protective shampoo (formerly pH maintenance shampoo) is formulated for regular, frequent washing.
