I'm bored of my current hair (kind of a 'Rachel') and quite fancied [[http://www.zimbio.com/Razored+Bob+Haircuts/articles/4/Kimberly+Caldwell+Blonde+Razored+Bob+2009 this funky type bob]] But I've had a bob of similar length before and it's always looked smooth and ordinary rather than like that. Would I need to use sea salt spray or something?
