History to Our Formulation
Watermans Grow More® Elixir draws inspiration from centuries of herbal practice used across ancient civilisations. Each carefully selected ingredient not only carries modern clinical credibility but also deep historical roots:
- Rosemary: Used in Ancient Greece and Rome to enhance memory and blood circulation, rosemary was traditionally rubbed into the scalp to stimulate hair growth. Its modern role as a natural DHT blocker continues this legacy.
- Biotin (Vitamin B7): While the vitamin itself is a more recent discovery, the nutrients found in biotin-rich foods like eggs and grains were prized in traditional diets for enhancing strength and vitality, including hair health.
- Yeast Extract (HAIRGENYL®): Fermented ingredients have been used in traditional Eastern remedies for centuries to rejuvenate skin and scalp health. Modern science now confirms its benefits in activating dermal papilla cells and increasing hair density.
- Lupine Protein (ANAGELINE®): Derived from sweet white lupine, a legume cultivated since ancient Mesopotamian times, this plant protein has long been used for its nutritional value. Today it plays a vital role in hormone-related hair loss support.
- Niacinamide & Allantoin: Both components align with historic practices of using plant-based compounds to reduce inflammation and support skin regeneration — creating the optimal environment for healthy follicles.
- Silica: Found in clay and earth used in early Roman and Egyptian skin rituals, silica continues to support stronger hair and improve resilience today.
By merging ancient wisdom with modern science, Watermans Grow More® Elixir offers a refined formula that both honours time-tested practices and delivers transformative hair health results.
