when my best friend went to pakistan the hair salon had these balls of hair that were kinda weaved together and glued under it was a clip so she could clip it into hair for height.
none of the salons in our area has those and she has very fine hair. she wanted to have the poof in teh front (bangs) and sit her dupatta and i realized we could easily make hairballs almost the same way but just saving hair from her brush. Mind you it took a long time but we kinda formed a shape, kept adding to it for a few weeks and hot glued a hair clip at the bottom and it worked.
