I’d be very wary of using a pro brand after using a Live box dye.
Schwarzkopf was renown for their box dye products containing metallic salts so you’ll need to do an incompatibility test first to be on the safe side.
I‘m wondering why you applied a box dye in the first place? I would tell any client that asked that I’m not insured to apply products that I haven’t purchased myself, mainly because you’ve no idea what strength the peroxide is, in them.
