Why we like it
The Moda Team Review
Most shampoos disrupt the pH the K18PEPTIDE™ needs to stay bonded. This one protects what the mask built — clients using it report their K18 results lasting noticeably longer between applications.

The client using K18 weekly but finding her hair reverts by day three. She is washing with a high-stripping clarifying shampoo. Switching to Damage Shield Shampoo extends her results to day five without any other change.

Moda stylist tipUse this as the cleanse step it was designed to be. For K18 treatment days, skip conditioner before the mask so the repair step has the cleanest canvas.
Reviews
Questions? We get them.
Good to know.
The questions we hear most about this product. If yours isn’t here, a real stylist will answer.
Ask ModaDo I have to use this shampoo with K18?
No, but it helps. This shampoo maintains the pH environment that keeps K18PEPTIDE™ bonded between washes. A stripping shampoo gradually reduces how long each mask application lasts.
Is this safe for colour-treated hair?
Yes — sulfate-free, colour-safe, and formulated specifically for chemically processed and colour-treated hair.
Which size should I buy?
53 ml trial, 250 ml everyday, 930 ml pro size for frequent washers.
Can I use this before the K18 Mask?
Yes, but if your hair has heavy buildup or hard-water minerals, I would use K18 Detox Shampoo before the Mask for a cleaner reset.
Who is this shampoo best for?
It is best for colour-treated, heat-styled, frizz-prone, or damage-prone hair that needs a protective everyday cleanse.
