How can I get curls in my hair that last?

I have wavy/straightish hair but wud like 2 get a curl in it>weneva I use curling irons it goes straight l8r on!!how do I get curls that last??

I have that type of hair too and I've had the same problem what I do is I get a 1/2 inch section of hair and spray it with eather spray gel or hairspray then I curl it in a spiral motion and then count to 10 and release slowly and you repeat then when your down you just seperate the chunky areas and set it how you want then spray with hair spray to set it works every time .. hope this helps ..miss v

im not that sure but my older sister had that same promblem and
what she did is she: curled it then hair sprayed it after but yeah
wgo have to leave the curlying iron on it for along time well it depends on what kind of hair your dealing with

Ok here are few ideas.
-Get your hair professionally permed although this can be very expensive
-Use hair spray on the curls after you've used the curling tongs
-Get some mousse and apply this on damp hair then scrunch the hair up to get ringlets
-Put the curling tongs on a higher heat setting
Hope this helped x

Well I have naturally curly hair soo this isnt a problem
but if this helps any heres my idea.
I say you should take a shower and wash your hair with a curling shampoo and
then brush your hair
then use your hands to mess it up a bit
and put mousse in in your hair
then flip your hair over and put more mousse in your hair.
then put your hair in a messy bun,
then the next day put more mousse.
OR
you can do that
except
use a DEFUSER to curl your hair with the mousse in it
it works good :D
