You can see my finger through the loc I'm splitting in the photo. I tightened the loc through the same hole until a Y was formed. (This is fairly easy to do.)I managed to separate 2 locs, leaving a 1 short and 1 long loc. The rest will be an ongoing process until at a reasonable length then I'll separate them. So far I've started the process of splitting 12 locs. I initially intended to split around 100, but I feel some are too thick and yet too thin to be divided. Besides she might end up with a lion's mane. So I am aiming to split 20-40 locs. Only the thickest locs will get split.
