Before starting chemo I was given a prescription to choose a wig, I wanted one very close to my own hair, colour and style.
I didn't want anything that was vastly different from my own hair, as that would have alerted persons to the fact it couldn't possibly be my own hair.
I did infact end up paying about £50 extra to get a non prescription version, not real hair but the one I tried that was suitable for requirements.
I don't know if a real hair one at the time would put me off, but maybe the cost may.
