How do I put weave on a bald/low cut hair style without showing tracks?

My friend has just recovered from chemo and she wants a weave instead of a wig. I want to do it for her, but I don't know how to cover the tracks because she doesn't have enough hair to cover over it.How do I put weave on a bald/low cut hair style without showing tracks?
well she should try a lace front weave but she might have to rock a wig so try especiallyyours.com they have some fly wigs there
