I too was diagnosed with SD and a scalp infection after fin. My scalp itches, is red and has those weird white flakes coming off. And as a bonus to this, my scalp still sweats like crazy! I too think in many situations how the “old me” would be enjoying the situation…hairloss combined with all these fin-induced problems is depressing as hell.
Edit: You should get that under control as if it gets bad it can cause hairloss.
