The Story

A lightweight, biotech-formulated hair oil designed for Unisex use and all hair types. Targets structural damage and frizz across two hair layers while boosting surface shine. Natural emollients—avocado and sunflower oils—plus squalane and hemicualane smooth and nourish the fibre. Clinical-backed repair and thermal defence up to 232 °C make it suitable as a daily finishing and protective step in refined grooming routines.

Dispense 1–2 drops into palms. Warm and apply through mid-lengths to ends on damp or dry hair. Style as usual. Reapply sparingly for extra shine or heat protection.

Blend of caprylyl caprylate/caprate esters with squalane, avocado and sunflower oils for lightweight nourishment. Hemicualane and SH-oligopeptide-78 support cuticle smoothing and repair. Silicone-free; contains fragrance and benzyl alcohol as preservative.

About K18

K18: Pioneers of Biomimetic Hairscience

Provenance: United States

K18 is a United States haircare brand positioned around biomimetic hairscience and biotechnology-led formulation. Its assortment on Ellie Jules spans hair care and hair oils, with a focused edit built for cleanse, treat, and style routines.

The brand states its approach is biology-first, with products designed to work with hair’s structure rather than mask damage. Within the current collection, K18’s Molecular Hair Oil stands as the clearest hero, supported by Pro Repair and Peptide Prep lines that reflect the brand’s repair-led philosophy.

K18 matters because it represents a more technical direction in contemporary haircare, combining salon-facing credibility with a concise, ingredient-led range. The brand states it is beloved by professionals and at-home users in more than 100 countries, and its position is defined by repair science, not broad category breadth.
