You may have heard this many times before, but a healthy diet is really important if you want to have great hair.

The stars that look the best are the ones that eat the right foods and focus on a good diet. Gwyneth Paltrow and Heidi Klum are great examples and look great without starving themselves or resorting to strange diets.

There are a few key things that you need to make sure you get enough of that will help your hair look at its best.

The first is to drink plenty of water, this gives the hair its shine and without enough it can leave your hair lank and frizzy. The usual recommendation is eight glasses a day, but don’t stick rigidly to this, just drink as much as you can.

Secondly, protein is really important to your hair as this is what it’s made of, so be sure to eat enough dairy and meat products.

Minerals like iron, zinc and copper are also really important.

The iron helps deliver oxygen to your hair to keep it alive and fresh looking, so eat plenty of red meat and dark green veggies.

Zinc is effective in keeping the hair strong, and prevents the hair falling out; it can be found in seafood and meat.

Copper is really important in maintaining the colour of your hair, and enough of this will really give your hair colour a boost, so make sure you eat enough shellfish, seeds and fresh vegetables.

Vitamins are also effective in maintaining a good scalp and a great overall condition of your hair, especially vitamins A, B and C. These can be found in fruits and vegetables.

A great celebrity secret is the sweet potato, which is full of vitamins A and B and other great nutrients which will give your hair great life and body.
