diva, I get after it with tweezers. I know it sounds tedious, but I start at the front and work into the hairline, pulling the hairs at an angle. I don't like the thinning shears, cause I found little hairs that stick up afterward, but if you use them I suggest you don't cut in the areas where you want to wear a part, ie center or left side. Just work around that area. I have a lf I have been thinning for a couple of weeks cause it's so thick, but I use tweezers.
I don't like using chemicals on my lfs if possible.
Ok I am having the same problem so this is helpful. I have a curly unit and it's too thick around the hairline, if you use tweezer how long does it take and should the hair be wet when tweezing?
