In reply to matnoo: I think it is as follows but will probably be corrected by some ethics know-all:
Redpoint - a worked sports climbing route (i.e. practised over and over on top-rope) which is then climbed clean, in one push, placing all quick-draws. Pre-placing the QDs is technically called a pinkpoint but there is little distinction between red and pink points nowadays (i.e. redpoints used pre-placed QDs)
Headpoint - a worked route (top-rope practise) that is eventually climbed in traditional style or soloed. Such routes are normally hard and have little/no adequate gear. The term is basically a trad style redpoint but it is deemed unethical to pre-place the trad gear (normally).
