How to curl your hair?

I have naturally straight hair. It doesn't curl well, like when I curl it with an iron, the curls only stay in for an hour - an hour and a half. Is there a way to make the curls stay? I heard that you can put hairspray in your hair BEFORE you curl it and they stay well. Does that work, or is that not safe for your hair? Thanks!How to curl your hair?
That works great and no it does not hurt your hair any more that spraying it after. It will sizzle a little if it is still wet when you put the iron on it but that is to be expected and it will make your iron sticky after a while. I recomend getting rollers that you can roll your hair on wet and let dry. Like Perm rods if you want kinky curls or maybe sponge rollers if you want bigger curls. That is what I used to do. It takes forever to dry and you have to use a dryer for a while but they stayed for a long time when i did that.How to curl your hair?
it does work it u put it then curl it

because i also have really straight asian like hair

and its really annoying that i cant curl it

but this one lady did it for me and she put hairspray before curling

and it stayed for the whole day and i was actually surprised

as it goes for damaging.

im not really sure but ppl have said that it damages your hair

but i dont curl my hair often

i think like once or twice wont hurt your hair
lots of hairspray! aerosol works the best.

first section your hair into 4 sections. bottom, then work your way up. take a section spray it, wrap it around the barrel, before you release it spray it again and hold it for a few seconds. do your whole head like this and then run your fingers through to separate the curls then spray really well.
