GROW LONG AND STRONG.

THE FOUNDATION FOR STRONGER, THICKER-LOOKING HAIR. 

The low down: Your complete protein-powered routine for stronger, thicker-looking hair. The shampoo gently cleanses the scalp, creating the perfect environment for healthy-looking growth, while the conditioner nourishes and fortifies fragile, breakage-prone hair from root to tip. The leave in conditioner strengthens hair, helping to prevent breakage for soft, manageable, healthier-looking hair.

Marks top tip: Healthy hair starts at the scalp. Massage the shampoo thoroughly to boost circulation, then follow with the conditioner and leave on for up to five minutes. Use the treatment for maximum repair and finish with the serum to seal in moisture, reduce breakage, and support long, strong, resilient hair.

Quantity

Who’s it for: Suitable for all hair types - perfect for anyone looking to boost strength, support growth or minimise breakage.

Why you’ll love it: This complete routine nourishes, strengthens and protects hair from root to tip. Hair feels stronger, looks fuller, and is better supported against breakage, while the scalp is balanced and energised for healthier-looking growth.

The star of the show: Rosemary oil and caffeine work together to energise the scalp and boost circulation, helping support a healthy growth environment and reduce thinning linked to DHT.

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