How long was Mad Max a Blood Bag?

I only ask because how did he shave after he was branded ‘feral’ and muzzled? 
Do you think NOX came and shaved him every other day? “Mustn’t have a hairy Blood Bag, wouldn’t be shiny. The other War Boys will talk.”

Maybe Joe harvested the hair to fill his bedding. He seems like a sensible, eco-friendly sort.
