K18 Peptide Prep Detox Shampoo

Step 1: Wet hair thoroughly. Apply a 10-cent coin sized amount of K18 Detox Shampoo to the scalp and lengths.

Step 2: Lather and massage for 60 seconds. Allow the cleansing system to lift build-up before rinsing.

Step 3: Rinse thoroughly. Do not apply conditioner before the K18 Leave-In Mask if you are doing a full K18 treatment.

Step 4: For deep repair, apply the K18 Leave-In Mask on damp towel-dried hair for 4 minutes, then layer K18 Repair Oil. On non-treatment days, follow with K18 Damage Shield Protective Conditioner.

Pro tip: Use once a week before your K18 Mask for the strongest repair result.

What does K18 Peptide Prep Detox Shampoo do?
It is a colour-safe clarifying shampoo formulated with the K18PEPTIDE. It removes product build-up, hard water minerals and pollution while preparing the hair for repair treatments.

Is K18 Detox Shampoo colour-safe?
Yes. Unlike most clarifying shampoos, it is gentle enough for colour-treated, blonded and chemically treated hair.

How often should I use it?
Use once a week as a reset, or before applying the K18 Leave-In Mask for maximum repair. Reduce frequency if hair feels dry.

Should I follow with a conditioner?
Yes. On non-treatment days, follow with a hydrating conditioner or mask to restore moisture after clarifying.

Will it strip my colour?
No. The formula is balanced with the K18PEPTIDE so it cleanses without stripping pigment or compromising the cuticle.

What sizes does it come in?
Available in 250ml and a 53ml travel size.

Is K18 Detox Shampoo vegan?
Yes. K18 Detox Shampoo is vegan, cruelty-free and sulphate free.
