Pom Kun and Pom Kin Lued are different.
Pom Kun is the thick (very thick, thicker than your normal strand), black strand, and very bumpy-curly (not wavey, but curly - zig zag). After you pull it, it may even feel better and relief from the itch. These strands are ones that will get gray first or faster.
Pom Kin Lued is thick hair that is real bright red. Which you will notice right away since we tend to have all black hair. They can be curly-zig zag as well. But i dont know for sure if it is sucking blood...? But I think it gots it name cause of the bright red color.
Either way, if pulling a few of these strands, you will not go bald. In fact, they will grow back, thicker, curlier, more red or more black, and maybe times 2 the amount you pulled, like gray hair.
For me, it never fails, if i have a small itch somewhere, that one of these type of strands are there. And when i pull it, the itch goes away. It might be a myth, but it helps me just to pull 1 or 2 strands of hair. Compared to the amount of hair i shed per day, 1 or 2 strands isnt going to do anything.
