What is K18 PEPTIDE PREP™ Detox Shampoo?

K18 PEPTIDE PREP™ Detox Shampoo is a colour-safe, non-stripping clarifying shampoo designed to deeply cleanse the hair and scalp. Its pH-optimised formula removes excess product buildup, sebum, dirt, oils and metals while helping leave hair refreshed and ready for the next step in your routine.

Powered by active skincare-inspired ingredients and K18PEPTIDE™, the formula provides an effective deeper cleanse without stripping the hair or interfering with your colour.

Who is it best for?

K18 PEPTIDE PREP™ Detox Shampoo may suit you if your hair or scalp:

• has excess product buildup
• becomes oily or has excess sebum
• needs a deeper cleanse than your regular shampoo
• is exposed to metals found in hard or tap water
• feels weighed down by heavy product buildup
• needs clarifying without stripping the hair
• is colour-treated and needs a colour-safe clarifying shampoo
• is being prepared for K18 molecular repair formulas

K18 recommends swapping your regular shampoo for this deeper cleanse once a week or as needed.

What problem does it solve?

Product buildup, excess sebum, oils, dirt and metals from hard or tap water can accumulate on the hair and scalp.

K18 PEPTIDE PREP™ Detox Shampoo is designed to remove this excess buildup while maintaining a non-stripping cleanse. According to K18, just one wash reduces 99% of product buildup, 95% of sebum and 76% of copper.

The formula also targets common metals found in tap and hard water, including nickel, cadmium, lead, zinc and iron, which K18 states can contribute to dullness and buildup on the hair.

By removing buildup without leaving fillers or deposits behind, the shampoo creates a clean canvas for optimal results from K18 molecular repair formulas.

Millies Expert Advice

K18 PEPTIDE PREP™ Detox Shampoo is designed as a deeper cleanse rather than a replacement for your regular shampoo at every wash. Use it once a week or as needed when excess product, oil, sebum or buildup needs to be removed. Massage it thoroughly through the hair and scalp before rinsing, and repeat if needed.

Is K18 PEPTIDE PREP™ Detox Shampoo right for me?

Choose this if: you want a colour-safe clarifying shampoo that removes excess product buildup, sebum, oils, dirt and metals from hard or tap water without stripping the hair.

Consider another shampoo if: you don't need a deeper clarifying cleanse and are looking for your regular wash-day shampoo rather than a detox shampoo intended for once-weekly or as-needed use.
