I try every step that you did on the video. It didn't work, so I went to the Catwa Store and asked for a redelivery (maybe was a script problem or some like that). I applied my skin and tried again, this time recording on video:
Before this, i ask my wife to see if it was applied (maybe was my computer) and take a print screen:
So, as u can see o the video, when I apply the hairbase in layer 2 it doesn't appear. So, I apply the beard and it appears, but it disappears soon after. I really don't know what is happening because apparently, in your Justin head, it worked.
