Hey sorry this is is an old post but,,
Usually when I do it I tease it and then use göt2b glued hairspray and spray the everloving everything out of it, that stuff is like cement in a can but will come out with a quick shower, it's what people use to do mohawks and liberty spikes XD plus I usually mess with my hair and check in my phone every so often during the day to make sure it's still in place so I can fix it if I need to :3
Hope that helps! <3
