Nowadays, celebrities often change their hair from short to long all in the space of a red carpet appearance. Now unless they are using some sort of extremely powerful hair growth product you can be sure that they are using hair extensions! One day your favourite celeb will be spotted sporting a funky bob cut and the next they have long flowing locks, so how do they do it? The secret is hair extensions and they can be for everyone, not just celebs. However, if you have short hair you will need to carefully consider what type of extension is best for you as some methods are not suitable for short hair.
