With the damaging elements of today environment, pollution and manmade chemicals can all help lead to unhealthy hair, and unhealthy hair can lead to a distinct lack of natural hair growth so it is very important and essential that we try to do our best to look after our hair and compensate for all the bad elements around that are very bad for our hair and the ways in which we can do that all vary, for instance it is of the up most importance that if you want a lot of natural hair growth you make sure that you are having a very healthy and balanced diet, one that is rich in fruit and vegetables which help with the vitamins needed for a healthy head of hair, fish is also particularly good food for hair as it is rich in oils, it is these oils that can help balance the natural oils in your hair which can stop it from becoming either too greasy or too dry.  The next thing to look at is whether you hair is overexposed to the sunlight as although vitamin D which our body produces from sunlight is good for your natural hair growth too much sun can dry out your hair and make it become brittle, using hot appliances on your hair for instance hairdryers or straightening irons can also have a drying effect on your hair and can even burn your hair, this can then make it look really limp so always use these appliances with caution.
