http://en.wikipedia.org/wiki/Dreadlocks
Dreadlocks are mainly a Male hair style and although they originated in Africa they are mainly associated with the West Indies and Caribbean culture now.
A guy on my old college bus had the most amazing dreadlocks. I nicknamed him Dreads and had the biggest crush on him. Never ever did pluck up the courage to talk to him!
Good point bb, what was the reason that someone felt the need to even think about this, let alone count it up (& no doubt, do a spreadsheet on it !) & why does it matter ?
