Castor oil is a vegetable oil with multiple benefits, used in cosmetics, hair care and for specific applications.
It is particularly known for stimulating hair growth and strengthening its structure.
For hair:
Apply the oil directly to the scalp and lengths.
Massage gently to stimulate blood circulation.
Leave on for 30 minutes to several hours, or even overnight (covering your hair with a cap).
Rinse with a mild shampoo (sometimes two washes are necessary to remove the oil).
Tip: Mix it with another lighter oil (like coconut oil or argan oil) to make it easier to apply.
