Concentrated oil blend with Argan, Camellia and Marula oils helps smooth fibres and seal split ends. Lightweight, perfumed formula can be used as a leave-in or before styling for long-lasting frizz control.


Silky, frizz-controlled finish – with Argan, Camellia and Marula oils

A concentrated blend of Argan, Camellia and Marula oils coats hair fibres to help seal the appearance of split ends while smoothing the fibre surface. The formulation targets surface-level frizz for a more uniform strand texture.

Hair looks shinier and feels smoother after application, making styling quicker and more predictable. Frizz control lasts through routine styling, helping hair appear healthier.

Lightweight, everyday nourishment – thanks to a non-greasy concentrated formula

The oil is designed to be lightweight and fragranced with the brand's signature perfume, allowing 1–2 pumps to spread thinly across wet or dry hair. The concentrated nature means small amounts deliver noticeable effects.

Small doses avoid weighing hair down, so daily use is practical for many hair types. Manageability improves without an oily finish, suitable for leave-in routines.

Heat protection for styled hair – with a strengthening, protective blend

Formulation states strengthening and protection from heat when used before styling, so the oil acts as a preparatory layer prior to heated tools. Oils help smooth strands to reduce stress during styling.

Applying before styling helps protect hair during heat-based styling and supports stronger-looking lengths. Styling feels easier and hair is less prone to visible heat-related damage.
