i am a school teacher who my students say does not look like a school teacher and that i look more like a model .i tell them i dont need so many compliments but then who does not like compliments especially from the flirty kind of boy students .we have a prom night coming up so i was thinking that i could do somrething really whacky with my hair,so my colleague suggested that i do a messy look for my short hair,What are the kind of materials that are used to get a messy look?and for how long does the messy hair last till?i hope till the next day
