American cancer society will give you one for free. They also have " look good feel better" classes where you get free high end makeup and they show you how to use it. Google their number and call them. They called me once I was diagnosed.There are many organizations that might help you get a wig, ask the social worker at your cancer center if she knows any. I bought one for $70 and got one made for me for free.

I ordered mine from Headcovers.com and got a wig kit to go along with the wig.

I bought quite an expensive wig, along with some chemo wraps before I started chemo. I haven't worn the wig once (it was lovely but just didn't feel right). I wore the chemo wraps a couple of times but then I found Wrapunzel! It is (a) a Facebook group for women who choose to wrap their hair for various reasons, (b) a YouTube channel with lots of videos showing you how to wrap your hair, (c) a non-judgemental support group for those who choose to wrap, (d) an online store that gives help to those who wrap due to chemotherapy treatment.
I absolutely love wrapping and feel rather special and regal when I do so, not at all like wearing the pre-tied chemo wraps.
Definitely worth checking out!

Hi,
I found some great ones from China on the internet,the trick is to take it to a good hairdresser, and have it cut to suit you, they never look good right out of the packet, even the expensive ones. I got 6 for under 200 aus dollars. Had a lot of fun changing them around the nurses would say they look forward to seeing my new look each week for chemo.
I always had short hair so I experimented with lots of long hair wigs.
Do what makes you feel good, wig scarf or bald.
