How It Works

K18’s biomimetic peptide technology is designed to support hair’s inner structure so strands feel more resilient and look healthier over time. Unlike traditional rinse-off masks that mainly coat the surface, this leave-in treatment is intended to work within the hair fibre during the 4-minute activation window.

K18 Leave-In Molecular Repair Hair Mask FAQs

Do I use conditioner before K18?

No - shampoo only, then towel dry and apply K18. Conditioner can coat the hair and reduce how well the mask can work. If you still need extra softness, you can use a leave-in conditioner or styling product after the 4-minute window.

How long do I leave K18 on for?

Wait 4 minutes after applying to allow it to activate. Do not rinse. After 4 minutes, you can add styling products and style as normal.

How much product should I use?

Start with 1 pump on towel-dried hair and add more only if needed depending on length, thickness and level of damage. Work evenly from ends to roots, one pump at a time.

Who is it best for?

Anyone with damage from colouring/bleaching, chemical services, or heat styling - or hair that feels rough, weak, stretchy, frizzy or prone to breakage.

K18 Leave-In Molecular Repair Hair Mask Review

The team at dPharmacy rate K18 as one of the highest impact “reset” treatments for compromised hair because it’s fast, leave-in and results-focused. The key is using it correctly: shampoo only, towel dry thoroughly, apply sparingly, and give it the full 4-minute activation time before layering other products. For very damaged hair, use it consistently over several washes, then maintain as needed.
