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 colour 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.
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 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.

    Five stars are well deserved!

    I’m going to have to get the bigger bottle for this because the shampoo is excellent! I love how it’s unscented/lightly scented and has my hair feeling cleansed but soft!

    Pretty good value and doesn't overstrip

    Got the mini set and both lasted me awhile. Were really effective in my hair and I have very thick, curly hair.

    Love it!

    I’ve tried this my past couple washes and can say my hair feels so much healthier and even thicker. I used to use heat on my hair a lot and have been on a journey to get it back to being healthy and this one has definitely helped so far

    Love!!

    I was recommended this product from a coworker and it did not disappoint! I had been using so many different products back then to get my hair to what it so easily became now after using k18! It freshened and repaired my very heat damaged hair! After my first wash with k18 shampoo and conditioner, I noticed and felt the difference, my hair is less frizzy, stronger and silky smooth! I love it and highly recommend it!
