Eyebrow threading gives the brows the beautiful defined look, that no other hair removal method can do because it is such a precise technique. The hairs do not have to be long in length to get threaded. Also because the thread can get the finest (peachy) hairs out, it gives a defined look. That is another reason why your eyebrow hair doesn't grow back as quickly because every single hair is taken out every time you get threaded.
