What is Castor Oil?

Castor oil is a natural vegetable oil extracted from the seeds of the Ricinus communis plant. It is rich in ricinoleic acid, a type of fatty acid that may promote hair growth and nourish hair follicles.

Types of Castor Oil

• Cold-Pressed Castor Oil – Extracted without heat, retaining its nutrients.
• Jamaican Black Castor Oil (JBCO) – Roasted before extraction, making it more alkaline and effective for thicker hair.
• Hydrogenated Castor Oil – Used mainly in cosmetics rather than for hair growth.

How Does Castor Oil Help Eyebrows and Lashes?

1. Promotes Hair Growth

Ricinoleic acid in castor oil helps boost circulation to hair follicles, which may stimulate growth.

2. Strengthens Hair

The oil penetrates deep into the hair shaft, preventing breakage and improving elasticity.

3. Moisturizes and Conditions

Castor oil hydrates dry lashes and eyebrows, preventing brittleness and thinning.

4. Fights Infections

With its antibacterial and antifungal properties, castor oil can help keep follicles healthy.
