My friend had very thin hair even when we were at school. She has now lost a lot of her hair and wears a wig if we go out. Her eyebrows have also nearly vanished so she has had them laminated. If you look really closely you can see that they aren't quite natural but she does look as if she still has eyebrows.
Your friend sounds like me. I’d be prepared to try something that wouldn’t last for very long if it looked awful. I put eyebrow powder on the few hairs I have left on my brows but I fear that, if my eyesight was better I’d look at myself and realise how awful they look.
