I did that in the eyebrow area where it was thick. Just the very tip went in it was a 43 forked, the only other needle I’ve ever used, the only one I’ve ever broke. I couldn’t get it out with anything. Pushing didn’t work either. Good think the baby is a keeper, you can’t see or feel it.
It’s happend to me once. I really couldn’t find it. I just kept going, rooted the hair, glued it in… When the glue dried, I noticed a brown spot inside the head. Turns out the needle was still there and had rusted from the moisture in the glue.
