Straightener problems >.<

well I have kinda wavy hair, but I straighten it like every day for school.
but like, right after like an hour or 30 minutes, my hair goes kinda wavy again..
like the ends flip out, or go in..

and its not straight, and it gets on my nerves!!
what...

can I do to get my hair BOARD straight for all day?

use hair spray, or a product which keeps your hair straight.

dose your straightener use steam? if not - that may be it! buy a straightener that uses steam, cause that worked for my friend who has wavy hair! another option would be for you to perm it straight! - if you're allowed!

Go to a hair salon and ask about 'hair rebonding', it makes your hair super straight! It may cost a bit but I love it, it lasts for a year, and more than a year if you take care of your hair really well.

make sure you dont get your hair wet because thats one thing that wont work just dont wet it with water or maybe during PE you sweat and it flips some hair out but if it not that try what they said

1.) do it in sections
2.)thin out a layer of your hair and put it in a pony
3.)do the same for three layers
4.)start with the bottom and work your way up
5.)with the bottom layer..take about an inch and spray it with hair spray
6.)then straighten it
7.)keep going inch by inch all the way around your head
8.)then go up to the middle layer...take it out of the pony and do the same as you did on the bottom layer.
9.)Then the go to the top layer,take it down, and do it the same
10.)then once you finished go over it once more with the straightner
11.)since you used hairspray it might be kind of stiff so shake your hair a little, run your fingers through it,and maybe brush it
12.) enjoy your sraight hair!!!

well I have really really curly hair and I straighten it for school too! and to keep it from flipping or going curly I just use hair spray and try a relaxer for you hair its like this treatment that you do on your hair and then when ever you straighten your hair it like makes it board straight!
