I was scared my hair would turn white so she washed the bleach off at 30 minutes instead of the normal 40.
The very top of my roots did turn light blonde but the rest of the root was a slightly darker yellow blonde. We had to tone a lot.
She thinks that leaving the bleach on longer will turn all my hair the right color next time.
Is this true? I did read that if you wash bleach out too early it can still look yellow and not light enough.
My hair was in good shape after and she said the ten extra minutes won't damage it.
