I suppose it can be to do with the wave you order too -- I imagine ordering a system with straight hair would be a way to avoid that issue --- I haven`t really noticed it with the systems I have worn up to now and they have been `slight wave`. I am thinking of ordering straight hair on my next system. After a few washes, it`s usually no longer an issue. Try a little gel in the meantime to take a little of the `bounce`out of it. Paul.
