I currently have a full head of foils - well they haven't been done since August - and whilst I am tempted to get them done again, I am finding the upkeep of them pretty expensive (£150 a time) and the main issue is just finding the time to sit in a salon for four hours! I struggle to find the time to get them done, I was meant to have them re-done before Christmas but had to cancel as my daughter had to be PCR'ed and the results didn't come back in time for me to go and I just haven't had time since.
I am really tempted to just home dye over the top of them, my hair is a medium brown and I would be looking to dye it a light brown/dark blonde - I am not going to attempt anything other than all over colour as I know I wouldn't do it well!
So before I consider it, is it ok to dye over old highlights / foils?
