Lots of useful information here, I personally like using a DIY hair toner.
I already had given myself a bleach bath/soap cap about a week ago. I went from level 6 to 8. If I give myself another bleach bath/soap cap this week, can I reach level 9 and possibly even level 10?
I've looked everywhere for the answer to this question band (well wouldn't you know) I can't find an answer.
That's one of those things that's hard to answer, but especially with so few details. So... maybe?
What colour is your hair naturally? Is it already dyed?
