short hair

Also, Lately I've been considering cutting my hair short. I've had a problem with mineral deficiencies and perhaps a gluten intolerance so to be honest...my hair hasn't been as thick as it should be over the past couple of years...so a shorter cut would be absolutely perfect. I stumbled across "Fashion is a playground"- a french fashion blog and fell in love with one of the featured model's haircuts.

What do you think? Should I go for it? or find something a little bit longer? Or perhaps even shorter?
