So my friend came into school one day with a huge bump in her hair; not a bad one a nice one;p I asked her how she got her hair like thinking she backcombed it... but then she told me she used a Bumpit. I really want one of these for them days i can't be asked to do anything with my hair but i'm too sure if i should buy it or not.. has anyone got any reveiws on Bumpits please? (: xx
