To start with, what you put into your body reflects on the outside. The most important nutrients for healthy hair are B-vitamins, zinc and iron. You can get these from meat, fish and poultry, but other great sources of these nutrients are eggs, dairy, nuts, pulses, soya and oats.
 

Another way of how to make your hair shiny is to use water, both on the inside (staying hydrated) and the outside. Giving your hair a cold rinse after every wash helps to close the scales on the outer layer of your hair, promoting shine. If you live in a hard water area, give your hair a final rinse with filtered or mineral water to prevent chalk deposits from settling on your hair.
