Apparently you're supposed to be using EMU oil at least twice a day to get regrowth benefits from it.
Check the HLH forum for a post by Chrome about this. He also said that it should absorb within 20 minutes. If you put a thin layer of oil on that dome, is most of it gone within 20 minutes?!
I'm going to switch over to EMU oil when I run out of Jojoba for my essential oil carrier base.
