ye for example take hermes franca who dyed his hair green for ufc 62, and before that at ufc 61 he had blonde highlights. i am sure he is not doing these things to improve his skill but rather his looks. Before he had his natural black hair and he looked like your average brazilian fighter. but his new hair color makes him stand out a bit. for those of you that dont know, hermes franca is the guy in my avatar, i had a huge pic of him in my signature but that is now all gone because we have to upgrade our memberships and pay money lol which i havn't done yet.
