Hi all - I had a go at home hair dye for the first time and was quite pleased until DH told me I had missed a massive patch at the back 


Clearly I can’t live like this for six weeks so what to do? 1) Dye whole head again - will hair be destroyed? Or 2) Try to (get DH to?) dye just missed patch and hope colour comes out exactly the same?
Please help as I am very sad!
