I am thinking DIY to save money but my last foils were really chunky and I wasn't too happy at all - I look a bit like a top deck - and now I have a BIG med dark brown stripe through the middle of my head. Usually my foils are quite fine and various shades but this was a gift voucher to a colour bar - who I thought would be colour specialists and do a good job but that wasn't the case....

Anyway normally I would just put a med brown over the top but am concerned they will go green. If I put a copper or burgundy over the top will they go pink? AND do I go or a semi or a perm colour?

Thanks!!
