Our black castor hair care capsules contain castor oil, hydrolyzed keratin, and keratin amino acids. Rich in nutrients, castor oil can deeply nourish damaged hair, repair dryness and split ends caused by hair coloring and environmental factors, and restore healthy and smooth hair. The way to use it is simple: clean your hair and keep it dry. Take out one of the products, squeeze it into the palm of your hand and apply it evenly to your hair and scalp. Gently massage until absorbed. And hydrolyzed keratin ingredients help strengthen hair structure, improve hair softness and shine, reduce frizz, and make hair smoother and easier to manage.
