I stopped using a timer on my bleach and went by feel instead, and I'm honestly not sure which way is right now
Last month my timer app died mid foiling so I just watched the lift and pulled when it looked ready. Got two clients who said their highlights were brighter than usual, but one lady in Falls Church said her scalp burned way more than normal. Now I'm torn between trusting the clock and trusting my eyes, and I've got 14 years behind the chair so it feels weird to even ask. Anyone here ditch the clock completely or do you still set one every single time?
