You may oil your hair regularly and apply natural hair masks but internal nourishment is as important as external care. Regular oiling or deep conditioning can improve the texture of your hair, but what you put into your body will make a greater difference. Oils improve blood circulation but Nutrition really helps in nourishing follicles for hair growth and strength.
Women opt for chemical laden solutions like protein shampoos, hair keratin/protein treatment to strengthen hair or oils to make hair smooth and silky. These do more harm than good or are only temporary solutions to hair health.
Diet goes a long way in helping deal with hair health concerns. Look at the food you put into your body before you try any of the above short-lived solutions.
