I am using a needle about the thickness of the hair, checked under magnification, as Bono says is the way to determine needle size. I am working on male leg hair, type III skin, with a size 4 needle. The 4 is closer in thickness to the hair than a 3.
Want I am curious about, is there a way one can tell if bad insertions are poor technique/misalignment with the right needle, or if/when it is appropriate to go down a size even if the needle is smaller than the hair?
Another quick question about insertion. I insert the needle into the follicle, slowly inserting smoothly. Then about halfway down sometimes I feel resistance (but no stick sensation), then suddenly feel a “pressure pop” and the needle pushes in (again with no sticking sensation or pain like a misaligned insertion.) Is this just from pushing past the anchor of the hair? I assume if I am poking through the follicle I assume I would feel a sticking/pain sensation?
