Good luck, you sound as if you are dealing with treatment well. I too wore a wig through chemo, and was encouraged to go for a warmer tone than my brown/grey hair. I felt remarkably well through chemo but a new hairdo with my wig was actually a bit of a boost. It was light and easy to look after. Of course I was happier when my own hair grew back, even though it didn't look anywhere as good to begin with! Keeping your morale up and feeling as good as possible is a huge asset as you go through treatment. Best wishes, only 6 more to go, you'll be looking at new hair growing in no time.
