Showerthought: I was over-processing my balayage for like a year
Honestly, I watched a client's hair just snap off when I was combing through a lightener mix I'd left on for 45 minutes. It was a wake-up call. Now I check the texture every 10 minutes and never go past 30, even with a 20 volume developer. Anyone else have a hard timing rule they stick to for lightening?
