Actually, there are two things that can happen.
Yes, you can get traction alopecia from clips, but also, the clips actually break off your hair. I had bald spots the exact shape of the clips but they eventually grew back, after about 6 months or a year of not wearing clips.
With clips, I usually recommend putting in at least two times as many clips as you actually need. You clip half of them (every other clip). Usually during the course of the day the clips become uncomfortable and you can just unclip each one and clip the one next to it. The ones that aren't clipped don't bother you since they sit flush with the edge of the piece.
