have questions?

Get started here

Is the formula of the DAMAGE SHIELD pH protective shampoo different from the PEPTIDE PREP™ pH maintenance shampoo?

No, the formula of the DAMAGE SHIELD pH protective shampoo is not different from the PEPTIDE PREP™ pH maintenance shampoo. Just the name has changed, the formulation you know and love is the same.

What makes the DAMAGE SHIELD pH protective shampoo special?

The DAMAGE SHIELD pH protective shampoo delivers healthier hair and scalp after just one wash. Its optimized pH helps maintain the hair cuticle, preventing excess water from entering the hair, which can cause damage, dullness, frizz, and tangling. With this shampoo, your color is maintained, hair feels strong, healthy, looks smooth with less frizz, and is easier to style with less tangles. This formula moisturizes hair without weighing it down, and preserves the scalp microbiome for a healthier-feeling scalp and a gentler cleanse. Coupled with the DAMAGE SHIELD protective conditioner, these formulas shield your healthiest hair from daily damage.

When do I use the DAMAGE SHIELD pH protective shampoo?

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

Why do I need both shampoos?

You need both shampoos to deliver the most effective clean while maintaining your hair + scalp health. Detox shampoo is engineered for less frequent heavy-duty washing, and DAMAGE SHIELD pH protective shampoo (previously pH maintenance shampoo) is engineered for frequent washing.

the DAMAGE SHIELD difference

DAMAGE SHIELD shampoo’s optimized pH reduces excess cuticle swelling during washing—preventing damage that causes dullness, frizz + tangling.

certified microbiome-friendly formula

Engineered with your hair’s optimal pH level in mind, this everyday cleanse keeps your scalp microbiome balanced for strong, smooth + healthy hair.
