In the salon now and we are trying out for the first time - how long can I leave it on before it ruins my hair!!

There isn't a set time everyones contributing factors differ. Keep checking your hair every 5 minutes.

Until it falls out. The same as when you would leave it on without Olaplex. Still have to use your eyes! When hair starts to get squishy without Olaplex in the bleach, it still looks the same squishy with Olaplex.
