Reduced hair breakage – With caffeine, biotin and hydrolysed lupin protein

Caffeine and biotin combine to stimulate circulation around follicles while hydrolysed lupin protein helps strengthen hair structure and reduce fragility. The formula is designed to target breakage as a leading cause of visible thinning.

Fewer snapped strands and stronger lengths with regular use, so hair appears fuller and more resilient.

Revitalised follicles – With rosemary and blood-flow stimulation

Rosemary delivers antioxidant and anti-inflammatory benefits to the scalp, while the formula is described as stimulating the deep dermal vascular plexus to move blood into dormant follicles. Improved circulation supports nutrient delivery to scalp tissue.

Dormant or undernourished follicles receive better blood flow, helping create conditions favourable to renewed, healthier growth.

Gentle, everyday care – With sulphate- and paraben-free, pH-neutral formulation

Sulphate- and paraben-free formulation with pH neutrality and Vegan Society approval avoids harsh stripping of the scalp. Leave-on use is recommended to allow active ingredients to penetrate the scalp effectively.

Safe for frequent use, pleasant-scented cleansing with reduced risk of irritation and suitable for vegans.
