K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask 15ml

K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask is a concentrated leave-in treatment designed to support hair that’s been compromised by bleach, colour, chemical services and heat styling. Powered by the patented K18PEPTIDE™, the lightweight cream works on a molecular level to help reconnect broken keratin chains, promoting the look of stronger, more resilient hair. The formula is vegan and colour-safe, with a soft floral fragrance featuring notes of jasmine and peony, and is suitable for all hair types seeking softness, smoothness and bounce.

This product fits easily into an existing haircare routine as a targeted repair step after shampooing. Hair should be shampooed and left free of conditioner so the peptide can work effectively, then towel-dried until damp. A small amount of mask is applied from ends to roots and left in the hair; there’s no need to rinse. Used over several washes and then as needed, it helps to support hair’s strength and elasticity while leaving lengths feeling smoother and more manageable.

How to Use:
Shampoo hair and rinse thoroughly, skipping conditioner. Towel-dry until hair is damp, then apply a small amount of K18 Leave-In Molecular Repair Hair Mask, starting with around a dime-sized amount and adding more if needed. Work the formula evenly from ends towards roots and leave on for four minutes. Do not rinse, then style as usual.

Frequency:
Use for the first four to six washes after a salon service or period of damage, then use as needed according to the product instructions.

Application Technique:
Apply to clean, damp hair in sections to ensure even coverage. Smooth through lengths with fingers or a comb, focusing on the most sensitised areas. Allow the product to sit undisturbed for four minutes before brushing, adding other styling products or using heat.

Best Practices:
Clarify with a detox shampoo if you’re a heavy product user, and always avoid conditioner before this step so the peptide can work effectively. Use sparingly, as the formula is concentrated, and allow time for absorption before styling.

Safety Tips:
Avoid contact with eyes. Use externally only. Discontinue use if irritation occurs and follow any additional guidance on the packaging. Keep out of reach of children.
