Key finding
90%
Ricinoleic acid content — the highest of any known oil
The brief.
Origin
Cultivated across the black-cotton soils of Gujarat and Rajasthan, the world's leading castor-producing regions (India supplies ~85% of global demand).
Extraction
First-press, hexane-free. Beans are hulled, cleaned, and cold-pressed under 40°C to preserve ricinoleic acid and vitamin E. The residual meal is composted, never solvent-extracted.
Sustainability
Castor plants are drought-hardy and grow on marginal soils where food crops fail. Our source cooperative pays growers a 12% premium above spot-market for verified pesticide-free harvest.
How it works.
The 90% ricinoleic acid in cold-pressed castor oil binds to prostaglandin receptors on the dermal papilla, prolonging the hair's anagen phase. Its unusually high viscosity forms a semi-occlusive film that traps moisture inside the cuticle — which is why hair feels dramatically softer after one application.

Heritage.
The record
Castor was buried with Egyptian nobility for cosmetic use in the afterlife — Ebers Papyrus (1550 BCE) documents its use as a scalp remedy. It appears in Sushruta Samhita (600 BCE) as an Ayurvedic hair oil, and Caribbean 'Jamaican Black Castor Oil' (roasted-bean variant) became the 20th-century global hair-growth staple.
Traditional use
Anointing oil in Ayurveda; Egyptian brow and lash blackener; Caribbean protective-styling sealant; West African braid finisher.
Naturally found in
- Native to East Africa (Ethiopia and Kenya)
- Cultivated commercially in India, Brazil, and China
- Wild along riverbanks across the tropics

People often ask.
Will castor oil really grow my eyebrows back?
It won't create new follicles, but it thickens and darkens the existing vellus hairs so brows look fuller within 6–8 weeks of nightly use.
How do I wash castor oil out?
Apply shampoo to dry hair first, emulsify with your fingers, then add water. Two washes are usually enough.
Cold-pressed vs Jamaican Black — which is better?
Cold-pressed is purer and less irritating; Jamaican Black is roasted (adding wood-ash alkalinity), which some find more penetrating but harsher. We chose cold-pressed for daily safety.
