Hi,
I tape my pieces all around,but i avoid the hair getting caught up in the tape by smearing a little brylcream or moisteriser onto the hairs at the ends with my hands,while the piece is upside down pinned onto a polyestryene head.
This helps the hairs stick together at the ends,when you are applying the piece,so the hairs don't go all over the place.It then easily combs out with a little spray of water,and if it stays on the piece it will help to condition it.
