I use neutrogena post shave face moisturizer. It's expensive but doesn't clog pores. I like how my skin feels after I use it.

I've used that for years! It's great. But in the hot summer months, I just splash witch hazel on the dome. I like the way witch hazel tightens the scalp. Only one drawback to witch hazel...it kinda sorta smells like URINE.
It's really a matter of what you prefer, and what works best for your scalp.
I usually use Witch hazel, but not everyday. My main choice is Bald Guyz moisture gel, and I will switch that up with HeadLube Matte or Glossy.
Now that Winter is coming, and with it more drier air, I think it may be time to use the Headlube's more, as they are more oil based and dont evaporate as quickly as the moisture gel.
Try experimenting to see what will give you the comfort and protection you need.
And don't forget sunscreen!
