Okay hold your hair up and spray hairspray under it. Then hold your had up side down and use a blow dryer to blow your hair upwards. Do this for about a minute until the hairspray is dried and then is should work. Good luck. (:
It helps if you use some bodifying spray or gel dry hair upside down. then take a section hold it up spray hairspray tease and then spray with hairspray again. It helps if you have a teasing comb. Then pick it smooth. An spray again.
