Always rinse with cold water after conditioning hair.
- Cold water seals the cuticle of the hair causing it to lie flat and thus making it shine.
- Cold water also stimulates blood flow in the scalp. The hot water from the shower causes the blood to rush to the surface of your skin while the cold water then causes it to rush back toward your internal organs. Hair follicles rely on good circulation of the blood to bring essential nutrients and oxygen to the hair.
- Other ways to stimulate blood flow include exercise and massage.
