I am 8 days post op.

My doctor claims I can remove scabs by shampooing in the shower on day 8:

This goes against the conventional wisdom to wait until day 10. What should I do?
I don't want to damage my hair follicles, but I'm also afraid I might do damage if I wait too long.

* I did not get my surgery at Lieberman & Parikh.
* I received PRP treatment during surgery, and I applied ATP spray for 4 days post-op.
