Blending onions and applying it to your hair may promote hair growth and scalp health. Onions contain sulfur, which is known to help improve blood circulation to the scalp and stimulate hair follicles. This can lead to stronger and healthier hair. However, the smell of onions may linger on your hair, so you may want to rinse thoroughly after applying the mixture. It is always a good idea to test a small patch of skin before applying any new treatment to your scalp to ensure you do not have any adverse reactions.
