"Love it makes my hair shine and no frizz " - Gracie

Why You’ll love it

Watch snapped, frizzy lengths look smoother, softer, and more controlled in minutes.

Helps reduce frizz and flyaways without flattening natural movement.

Leaves hair touchably soft, not sticky, crunchy, or oily.

Description

K18 Molecular Repair Hair Oil is a lightweight treatment that helps reverse damage from within.

This clever oil uses biomimetic peptides to travel deep into the hair’s inner layers, reconnecting broken keratin chains while plant oils smooth the surface. The texture feels silky but not greasy, sinking in quickly without weighing strands down.

Hair feels soft, flexible, and easier to style, with a satin, frizz-controlled finish that still looks natural. A subtle, clean scent makes it pleasant to use every day.

It’s ideal for dry, damaged, colour-treated, or heat-styled hair, and can be used on damp or dry hair whenever you need extra repair and shine. Expect hair that looks smoother, feels stronger, and behaves better with every use.

Directions

How To Use K18 Molecular Repair Hair Oil

Apply 1–3 drops to clean, towel-dried hair.
Start from mid-lengths to ends, then lightly smooth over flyaways.
Comb or finger-comb to distribute evenly.
Style as usual; do not rinse.
Add 1–2 drops on dry hair for extra shine and frizz control.
