That would be a dumb mistake to give to someone. If no one says it like this, I will. Would never do that. Maybe if I know and talked to someone in RL for a long time, and then it still would be a big maybe.
I had the same problem. It happened when I put my viewer on a lower graphic setting. Then the hair looked really bad. I put ithe setting one higher, and it looked normal again.
Maybe that's the problem?
