your protective shampoo questions, answered
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.

smooth + shield all hair types

pH-optimized formula prevents frizz, dullness + tangles for everyone.

    Worth it!!

    Before and after pics of me trying to do a curly perm even though I already had curly dyed hair. It completely destroyed my hair.

    I decided to cut it off and start over. It's growing back so fast and it feels so much healthier. I bought the detox shampoo, hair oil, leave in hair mask and Damage Shield shampoo/conditioner. I know it's expensive but it is worth every penny

    Great recommendation from my stylist

    My stylist told me that K18 was the best on the market. I ordered it and have been using it for a few weeks now. I can already tell my hair is stronger and feels healthier. Less frizzy when it air dries. I'm a loyal customer now!
