ahhh you seem to have very hard to style hair but i dont know wether thats from straightner or not because idk your natural hairtexture..
an unorthodox way to get your hair all stiff and ready to style is;
hairspray it > straighten > comb out
(and abit risk of damaging hair slightly) but doesnt matter much as its semi-short and likely get it cut on regular
the combing will hurt if u dont hold your hair but does the job lol
haha the way it is now isnt that bad at all it goes up allright now all u need is practice
and please avoid shaving your head! Theres plenty of haircuts u can pick from ^^
