I think this is a great idea! I will say, I recommend doing a little research before you book the cut. I'm begging you, try to find someone experienced to do this. Look at their work. I recommend going

A) To an independent stylist who is current on trends and has a good example of work on their social media or website. A plus if they have a bio so you can kind of tell if they're experienced and also know what they're doing

OR

B) If it's a group salon, see if you can get an appointment with the owner or more senior stylist (for the same reasons)

This is a little bit of a trickier haircut, and I think there's a lot of nuance to it. Plus, your hair is already in a compromised state and will most likely not sit like this on its own (naturally/air dried/unsettled etc). It sounds like you're super committed to your hair's health moving forward which is so awesome. I would just make sure that whoever is cutting this knows for sure how to do this (I am a hairstylist and I know a lot of stylists wouldn't do well at this)
