If your hair is dry and you have not conditioned it then you are running the risk for splitting the ends. So to begin with, make sure that you shampoo well and use a conditioner unless of course your hair is oily. Towel dry it as there is no need to blow_dry your hair for the ponytail look. You might want to add a little bit of gel to give it a nice shiny look and to help keep those flyaway hairs under control.
Celebrities and magazines are a great source of finding a hairstyle for long hair as many celebrities change their style regularly. If you are looking for a new style which is in fashion and trendy, watching what the celebrities are doing with their hair on the red carpet is a perfect way to do this.
