K18 Damage Shield Protective Shampoo

Everyday Protection Built Around K18 Science

K18 Damage Shield pH Protective Shampoo is the daily shampoo designed to maintain your K18 results and protect hair between treatments. It cleanses gently while working to shield the hair shaft from environmental and chemical damage, keeping your hair in the best possible condition for when you apply K18 again. If you are doing a K18 repair protocol, this is the shampoo to use on the weeks when you are not doing the K18 PEPTIDE PREP and mask cycle.

Best For

• Hair actively doing a K18 repair routine
• Color-treated or chemically processed hair needing daily protection
• Anyone wanting a pH-balanced shampoo that does not compromise repair work
• Hair that has already been treated with K18 and needs to maintain results

What It Helps With

K18 Damage Shield maintains a pH balance that keeps the hair cuticle closed and protected during washing. An open cuticle during shampooing is one of the ways hair loses moisture and takes on additional damage even without chemical exposure. By keeping the cuticle sealed, this shampoo preserves the repair work done by K18 and prevents everyday washing from undoing your progress.

How to Use

Wet hair and lather through from scalp to ends. Massage for 60 seconds and rinse thoroughly. Follow with K18 Damage Shield Protective Conditioner. Use as your everyday shampoo between K18 treatment days.

Pro Tip From Our Stylists

Rotate this shampoo with K18 PEPTIDE PREP Detox Shampoo. Use K18 Damage Shield for everyday washing and K18 PEPTIDE PREP on the weeks you are doing the K18 mask treatment. This keeps hair clean and protected without over-clarifying.
