It looks like you have oil on your needle. Did you clean it first with alcohol?? That’s really important to do before you start rooting with a new needle. Rooting takes a lot of practice, keep going you will eventually get better at it, we all do. If I could give you a few tips I would tell you to: Map your head so you have a plan to follow. Watch your spacing and don’t jump around the head you’ll only wind up getting in your own way. Pull out hair if you see too many hairs in a hole, your goal is to root only 1 - 2 hairs per hole. Plugs don’t look good and will keep a baby from selling. It all takes lots of practice and patience to finally learn but you WILL get it!! Keep up the good work!!
Needle tip: don’t use a needle with too many barbs cause that will really create plugs.
