LEAVE IN GROWTH ENHANCING CONDITIONER. 

THE FOUNDATION FOR STRONGER, THICKER-LOOKING HAIR.

The low down: A protein rich lightweight leave in conditioner that helps strengthen hair and prevents breakage.  Infused with Rosemary oil and caffeine to help stimulate scalp circulation and gently exfoliate, hydrate and nourish, this powerhouse formula supports stronger roots and helps reduce shedding — keeping your growth journey on track.

Marks top tip: Use it on damp hair at night — just spritz lightly and massage it into the scalp and roots. That’s when you’re giving the follicles the nudge they need to help encourage new growth

 

Quantity

Who’s it for: Suitable for all hair types — especially damaged hair prone to breakage and split ends.

Why you’ll love it: A lightweight, residue-free leave-in treatment that energises the scalp at the root while helping maintain a healthy, balanced environment for stronger-looking hair.

The star of the show: A dynamic blend of caffeine and rosemary oil works to invigorate the scalp, enhance circulation and promote fuller, healthier-looking hair from the root.

Scent sensation: A luminous amber fragrance blending saffron and jasmine with rich amberwood and cedar.
