The Scalp Health Gap
Textured hair demands a unique approach to care. Unlike straight hair, which can be washed daily, curly and coily textures require a more sophisticated rhythm. The moisture retention and detangling realities of textured hair often lead to a significant consumer whitespace. We bridge this gap with clinical precision, ensuring that every wash cycle restores the scalp's natural balance without compromising the integrity of the hair.
The Gold Standard

Formulation Goals
Moisture Lock
Preserving the natural lipid barrier to maintain deep hydration and prevent moisture loss in textured hair.
Slip & Detangle
Introducing clinical-grade slip to reduce friction and ease the daily ritual of brushing and styling.
Protective Style Support
Formulating for the realities of wash frequency and protective styling to ensure long-term scalp health.

THE SCALP RESEARCH
Leonine was born from a decade of clinical research at Procter & Gamble, where we pioneered the sourcing of high-performance selenium sulfide actives. We developed this treatment specifically for the unique moisture and detangling realities of textured hair, bridging the gap between pharmaceutical-grade efficacy and the everyday needs of the modern consumer.
