Fuller-looking hair – with Biotin, Keratin and Marine Collagen
Biotin and Keratin act as hair-building ingredients while Marine Collagen and Seaweed extract form a lightweight coating on each strand, increasing perceived bulk. The leave-in formulation allows those ingredients to remain on the hair until the next wash.
Creates the appearance of thicker, fuller hair without weighing styles down. Suitable for daily use as part of a regular shampoo and conditioner routine.
Tames frizz and boosts shine – with an anti-frizz moisturising formulation
Moisturising agents condition the hair surface to smooth cuticles and reduce flyaway fibres, while ingredients that add surface gloss enhance light reflection. The non-greasy base keeps the finish light.
Smoother, less frizzy hair that looks shinier and more polished throughout the day. Works well when styling damp or dry hair for tidy results.
Easy styling and long-lasting control – thanks to a lightweight leave-in formula
A non-greasy leave-in composition adheres to hair strands for prolonged conditioning and styling support, without build-up associated with heavier creams or oils. The formulation is free from parabens, SLS and SLES.
Quick to apply and simple to incorporate into existing routines, helping styles hold while maintaining a natural feel. Long-lasting, easy-to-manage results suitable for everyday wear.
