You put your bleach on your roots and you can see it lifting almost immediately! My hair does lift to yellow very fast anyway, but honestly, I was putting the bleach on just now and within I'd say 20-30 seconds it was already into the very, very brief red stage that I get. By the time I was on a couple of sections and I looked back underneath it was already yellow! I will be washing this off very soon lol
Amazing the difference temperature can make! Just shows how we all have to find our own trial and error timings depending on our hair and the climate we live in!
