hi,
might seem daft but i usually use colour liquid for darks and bio for whites
this week by accident i ordered liquid 2-1 instead of colour
now i read that only bio powder has bleaching agents so when i do a colour wash do i really need colour liquid or can i just use the mistaken 2-1 liquid as it wont have bleaching agent
if so why bother with special colour liquid if all liquids dont have bleaching agent ??
bit of a garble,well done if you understood the ???
