I ended up having to cancel my appt due to scheduling conflicts but am trying to make another appt within the next couple of weeks. But here is what hes told me so far. It's def 3 days of downtime. He said absolutely no washing it, styling it, headbands...anything. He even told me not to tuck it behind my ears. The Coppola actually coats the hair shaft, so if you do anything to it during those days, you risk "breaking" that coating, and you won't get the full effect of the treatment.
  After the 3 days, you still need to use the special shampoo and conditioner but you can style how you want it...flat iron, curlers, etc.
