The really high quality wigs are worth it imo. I have a synthetic one and it has been holding up really well. Depending on if you have a doctor or not, you might even be able to get it paid for by insurance or a healthcare system or whatnot.
Synthetic wigs are a bit cheaper but the natural human hair ones can be styled with irons and washed with normal shampoo. I have a specific shampoo for synthetic wigs but I might be wrong about if I actually need it or not.
I can wear mine everyday and it's not uncomfortable. I have yet to experience it over the summer though and I don't expect it to be super comfortable with the sweat and my growing natural hair underneath too.
I've been very successful with my wig. It's incredible because otherwise I wouldn't have socially transitioned for another year.
