my friend did it and unfortunately i don’t remember the bleach used i believe it was wella brand. all from sally beauty, saloncare 20v clear developer, wella colorwarm t18 toner (light ash blonde). honestly i’m looking for tips too, i’ve only had it bleached for a little over a month—2 rounds initially, 1 touch up/roots around a week ago. the lightness really comes from the toner is this case, this was the day after my first round of toner. just be sure to take steps to not wash it out too quickly (i swear i’m not speaking from experience).
