The salon I go to have started doing these, but it's €300 for a full head I saw on another board that a girl had gotten a set off Ebay for ~€60 and they were perfect.
Does anybody have any experience with them? How many do you need to do your full head? The set I was looking at has 8 pieces - 8", 7", 5", 2x3", 3x2". Would that be enough?
