Hi, a root perm will only add volume to your hair so that your hair has more body and will only last as long as it takes for your root area to grow longer. If you want curly hair all over then you will need a traditional perm. Any type of perm will cause damage to your hair because of the chemicals involved, but if you are willing to accept this and to look after your hair with regular treatments then there's no reason why you can't enjoy a perm. If you feel that your hairdresser cannot give you the perm you wish then the best option is to find one that will. Kind regards, Serah Schuster - THS Hair Consultant.
