Colouring regrowth of hair after chemo

Oh I know how you feel! My sister-in-law is a hairdresser and I am constantly asking (probably badgering really 😂) when I can get some colour. I have had some kind of gentle colour put in as to make it blonde is very harsh. She says that I need to be very kind to the new growth.
I finished chemo in May and I am taking Femara too. My lovely sister-in-law bought me a coloured hair mousse which worked a treat to get me through that first inch of growth phase - it was a lightIsh colour and washes out. I am hoping to get into the serious colour soon!
There is a book written by John Boyages - Breast Cancer. Taking Control. He is a cancer specialist and he actually recommends that women start dying their hair as soon as it comes back with some gentle dye as it is such a psychological boost. I don’t think it is a minor issue at all - ‘feeling’ good is just so important. After having no hair at all, I am just riding the waves of my crazy regrowth. I have also used Nioxin and another product Bondi Boost to get it to grow - I call them my hair fertilisers! Good luck 😀
