have questions?

Get started here

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.

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 client’s 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 the healthiest hair from daily damage.

Use this gentle shampoo for higher frequency washing like multiple wash services or clients with less buildup. 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 to deliver the most effective clean while maintaining your client’s 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.

OMG! The Best

This is the best shampoo I have used yet for hair. My hair is long, thick and course and very damaged and after one use of this shampoo I can see the difference I also used the used conditioner and oil but the difference is like night and day
