Hoping to get some advice from someone with more experience in this...
I used colourb4 on my hair yesterday. I'm not after a drastic colour change but I had a lot of colour build up with patches around the front that were nearly black rather than chestnut brown (I've been using L'Oreal Virginia for about a year). It worked really well - not a colour I want to keep as it's a bit too ginger and my grey roots are terrible - but a good base. My plan was to put a light ash brown semi permanent colour on today but I've woken up and it's looking darker than it was yesterday. Not back to what it was but definitely darker. I know I definitely rinsed for the right length of time cos I used a timer on my phone. So my dilemma is - should I go ahead and colour today or should I do another round of colourb4 first? The instructions say you can do it three times in one day but has anyone actually done that? Will it hurt my hair to do it again?
