I've had my hair cut into a shortish (about 2inches below ears) slightly graduated Bob. I'd like to be able to make the ends look a bit choppy/tousled/beachy as an alternative to the Anna Wintour-esque smooth blow dry (which I also like). What product would ache ive this? I imagine it would be something to rub in after drying? I've got coloured quite thick hair if that makes a difference
