When I take my system off, and I go to wash my shaved head (once weekly) I do it at night. I wash, then scrub my face/scalp with St. Ive's Apricot Scrub. It's an exfoliating scrub. THEN before bed I put face cream (pond's) mixed with jojoba oil all over my face/scalp.
I rest this overnight,and allow the jojoba oil (which is like human sebum) to nourish and refresh the area. I reattach first thing the next morning.
Remember jojoba oil is not actually an oil, so it does not negatively effect the attachment.
Anyway, you might want to try it, it has really helped me
