The Moda Take

A colour-safe detox shampoo that removes product buildup, mineral deposits and scalp residue — for hair that feels coated, dull or heavy, or when treatments have stopped working.

The Moda Team Review

The Peptide Prep Detox Shampoo is a targeted pre-treatment reset, not an everyday cleanse. If you have been using K18 and notice the results have plateaued — or if your hair always feels like there is something sitting on it no matter what you do — the Detox Shampoo is what clears the way. Product buildup, hard water mineral deposits and accumulated silicones all create a barrier on the hair shaft that prevents treatment ingredients from penetrating properly. The K18PEPTIDE™ cannot reconnect chains it cannot reach.

Used before the K18 Leave-In Mask on the wash day where the hair needs the deepest penetration, the Detox Shampoo removes that barrier and allows the mask to work at its maximum effectiveness. This is particularly relevant for clients who use heavy styling products regularly, live in areas with hard water, or have been on the same treatment routine for several weeks and feel their results have levelled off.

Despite its clarifying function, the formula is colour-safe and gentle enough not to strip colour significantly with occasional use. The K18PEPTIDEâ„¢ complex in the formula also provides a baseline repair benefit during the cleanse itself.

Key Active Ingredient(s)

  • Chelating agents: Bind to and remove mineral deposits from hard water that standard shampoos cannot dissolve.
  • Clarifying surfactants: Remove product buildup and silicone accumulation without stripping colour significantly when used occasionally.
  • K18PEPTIDEâ„¢ complex: Provides baseline repair activity even during the detox cleanse step.

How To Use

  1. Apply to wet hair in place of regular shampoo. Lather thoroughly and rinse.
  2. Follow immediately with K18 Damage Shield Conditioner and K18 Leave-In Mask for maximum treatment penetration on freshly cleared hair.
  3. Use weekly or monthly as needed — not every wash.

COMMON QUESTIONS

Good to Know

It depends on how quickly buildup accumulates. Heavy product users or those in hard water areas may benefit from weekly use. For most clients, every two to four weeks is enough for a meaningful reset.
Used occasionally it is colour-safe, but it is a more active cleanser than the Damage Shield Shampoo. Use it on a wash where colour freshness is not a concern — not immediately after a colour service.
Yes — always. The Detox Shampoo clears the path; applying K18 mask immediately after while the hair is freshly cleared gives the deepest penetration and the strongest repair result of the entire routine.
It is a detox shampoo, so follow the instructions and do not overuse it. It is designed to clarify without leaving hair over-stripped or easily tangled.
Yes. K18 specifically positions it for buildup and metals common in tap and hard water, including copper.
