Hi Angie
One other thing that i used to help me get by without colouring my hair was a product called Spilt Milk... Its a coloured powder that you brush onto the roots of your hair to hide any regrowth. Got me through the months of not being able to colour. You can buy it online. I was lucky enough to get through my 6 rounds of TCH with hair still on my head did lose quite a bit mainly around neck as the cap didnt come down that far. I only washed my hair once every 2 weeks ( gross i know ) but didnt want to touch it too much. I also didnt use any hairdryer or straightener anything with heat is a big no no. Good luck i hope it works for you x
