I cant begin to tell you how played out this style is. Rihanna did it and did it well, so did Cassie, but that was so 2012 and if you are still shaving off half your hair then you need to watch the trends more, everyone else has moved on.
To be honest you had to have the proper look to pull off the shaved side anyway, not everybody can pull off the half bald look. The only problem is, by the time you realize that it doesn’t go well with your face, you have already done the deed which could make for a very bad hair year for you.
However since it is 2013 we can safely say the bald sides era is over and hair evenness is back ‘in’. Salvage your dignity and don’t fall for another hair fad this year.
