K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask 50ml

K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask 50ml is a lightweight leave-in treatment designed to support hair that’s been stressed by colour, bleach, heat styling or chemical services. Powered by the patented K18PEPTIDE™, the formula works on the inner structure of the hair to help reconnect broken keratin chains, promoting stronger, more resilient strands. Hair is left feeling softer, smoother and more manageable, with a healthy-looking bounce and shine that suits a wide range of hair types and textures.

Used in place of a traditional rinse-out mask or conditioner, this cream-textured treatment fits easily into a simple wash-and-go routine. After shampooing, apply to clean, towel-dried hair and allow it to work for four minutes before styling. The vegan, cruelty-free formula is colour-safe and created to help reduce the look of damage from repeated salon services and daily heat styling, making it a thoughtful choice for anyone looking to care for compromised, sensitised or frequently processed hair.

How to Use:
Shampoo hair and rinse thoroughly, skipping conditioner. Towel-dry until the hair is damp, then apply a small amount of K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask, starting with 1–3 pumps or a dime-sized amount and adding more only if needed. Work the product evenly from ends towards roots and leave it on for 4 minutes before styling. Do not rinse out.

Frequency:
Use for the first 4–6 washes after a colouring or chemical service, then every 3–4 washes or as needed to help maintain hair strength.

Application Technique:
Apply to clean, damp hair in sections, smoothing the cream through mid-lengths and ends before lightly working any remaining product towards the roots. Allow the formula to absorb fully for 4 minutes, then comb through and style as usual.

Best Practices:
Use on product-free hair for best absorption. Avoid over-applying; a little goes a long way. Follow with your usual styling products only after the 4-minute processing time.

Safety Tips:
For external use only. Avoid contact with eyes. If irritation occurs, discontinue use and consult a professional. Keep out of reach of children and follow any additional guidance on the packaging.
