How can I keep my hair curly?

Curling irons only keep my hair curly for maybe an hour or two, hot roller's give me the best curls but keep getting flat after two to three hours, and i was told to also use pillow curlers when my hair is damp and sleep with them over night. My hair is still damp when I take my hair out so they too get flat after a little while. I like the hot roller curls the best. My hair dresser gave me hairspray that is made for curls to last longer, but it hasn't seemed to work. I love love love my hair curly, can anyone help?How can I keep my hair curly?
clean hair and lots of hairspray. best to put a styling lotion through while hair is damp, then blowdry until completely dry. take a section of hair, spray, then wrap around the barrel of a curling iron, but don't clamp it- just wrap. takes some practice. good luck!How can I keep my hair curly?
i would get the amika brand for curling or strighting
this isnt good for your hair but you put moose or gel in it b4 u curl it then while curling spray it with hair spray and if u need to blow dry ur hair while it is still in the curling iron
get a purm
