Description
Castor Carrier Oil is cold-pressed from the seeds of Ricinus communis, a nutrient-rich plant valued for its intensely hydrating properties. High in ricinoleic acid, it locks in moisture, soothes dry skin, and supports scalp and hair health. Frequently used in hair masks and body treatments, it enhances nourishment while forming a protective barrier. Its thick texture makes it ideal for dilution, improving absorption in essential oil formulations. A nourishing staple, it remains essential in restorative beauty and hair treatments.
