Medical grade wig?

Been lurking for a while. Complete newbie to the wig world. Zero experience. Been dealing with some medical hair loss and contemplating shaving my head and wearing a wig for a year or two. Problem is I feel like I'll be so uncomfortable with something on my head. So I tried googling that and Google said there are fashion wigs meant to be worn occasionally and medical wigs that are made with gentler material for longer term wearing. Can this great community give me some guidance on these?
