I faced this problem when on FEC. I could not stand the cold cap, so when my hair started to drop, I gave in and looked into getting a wig. It appeared that the local PCT had decided that only "in-patients" would receive full funding, and that "out-patients" must pay for their own wigs. Funding of wigs is apparently a local matter and ot a national directive.
My onc. nurse snorted, said that so far as she was concerned I was in the clinic and therefore was an in-patient, and completed thew form. Sadly the people ordering the wig messed it up so I ended paying for my own.
However, two points - talk to the team and find out what local rules are, and talk to your hairdresser.
Apart from that, this link is worth looking into: http://www.wigbank.com/
I donated mine to them and feel they are well worth supporting.
Another point, If you do get a wig, go to your hairdresser and ask him/her to shape it on your head. The wigs tend to be too full of hair, and thinning can do marvels.
