Painting hair takes hours, too. Not quite as many but a lot. Bald is beautiful with hats and bows. I don’t heat my heads for rooting. I fill them with poly pellets up to the bottom of the neck flange and pack them tightly with paper towels. This prevents the vinyl from ‘giving’ and you’ll break fewer needles. I always start in the back at the bottom and work my way around and up and end with the crown. Otherwise, for me, the hair above it gets in the way. I also cover the first round by pulling a slice of a knee high stocking over it (from the top of the head) before moving up to the next section. It keeps the hair from matting and tangling while I work. Then I slide it off over the neck and put it back on over each round. In time, you’ll find what works best for you but right now you don’t have a lot of time for trial and error.
