I use needle-nose pliers or tweezers to yank the stubs and glue out.

And as for how many holes, it depends on the quality of doll. Higher-quality ones tend to have more hair and more holes in the head. Dollar store ones tend to have less hair, because of having fewer holes.

On average, if I reroot, it takes me close to 10 hours for a Monster High, Ever After High, Barbie, or similar sized doll. if I make a wig, it can take a bit longer, because of all the prep work I have to do before I can actually make the wig.
