I need to fix this hair problem !! >___<?

-everytime i finished straightening my hair it's good but like 5-10 min after it's all poofy agian and i hate it so much -___- is there any way to fix that ( i also use a heat protecter that says it keeps hair flat all day no matter if it's humid outside ) and on my right side my hair curls up on the front it's so annoying ... is there a way to fix that too?Well what kind of straightener do you have? I have a her styler the colorful seasons kind it's light blue. It's a good iron. Have you tried Dove heat defense? it's good but if you're gonna straighten your hair make sure you're in the air conditioning. I know it sucks......humidity messes mine up too from just sitting outside for a few minutes. >.< It happens to lots of girls. Make sure you're gonna be in a car or a place where's there air conditioning or wait until the fall and winter seasons to start straightening it.Otherwise throw it up in a ponytail (medium or loose) and go. Hope this helps.

God bless.
Sometimes you can find shampoos used for that and maybe you have split ends or sometimes its just the type of Straight hair mines sorta the same way except mines when i curl it and the 5 or 10 minutes later it gets Straight again
it's probably just your hair type.

trimming spit ends helps, if you have any

Pantene Smooth & Sleek Shampoo does a great job

use Pantene Smooth & Sleek Complete Therapy Conditioner too.
