People often ask you how long have you had your locks. The reason i suppose is that they want to know how fast you hair has grown in the period of time.
I like my locks in this short length. Basically because it is very easy to handle and i believe that when your hair is shorter it seems to have more body.
Once again it is a matter of preference as well as the shape of your face as some people their face compliments their hair length. I am no expert but i believe that persons with long faces are suited to long hair, whereas persons with round faces are suited to shorter hair.
Please feel free to comment and enlighten me.
