Castor OilBenefits, how to use & safety
Thick, sticky, and overhyped for growth.
What is Castor Oil?
Castor oil is a thick oil rich in ricinoleic acid. It is a classic in Indian hair and skin care, and social media has made it famous for eyebrows and lashes. It is a superb sealant, but claims that it regrows hair are not backed by good evidence.
How it works
Its thick consistency coats hair and skin to lock in moisture and reduce breakage. Ricinoleic acid may also have mild anti-inflammatory action.
