I've changed bleach from vario to blondme 9+... twice I've done a full head of foils on separate clients. First client had natural root growth level 6 and second client had natural root growth level 5. I used 9% on both clients and mid length and ends turned a lovely yellow/pale yellow and toned really nice with clynol crystal... but the roots come out orange!! Crystal hardly budged it.. Opinions please??
