In case you haven’t seen this, these are the guidelines from Skalp: https://skalp.com/faq/aftercare/
I had a 4th session last Friday (5 days ago). I am already wet shaving again, albeit with great care. I went to the gym today, sweated like a mofo and then showered and moisturised my head.
Generally speaking, I moisturise 2/3 times a day. Every morning I use Nivea sensitive post balm after I wet shave mainly back and sides and L’Oréal matte on top. Late afternoon I put some more L’Oréal on. Before bed I use Johnson’s baby lotion.
Just relax mate and moisturise away!
