So, if you have the arm hair of a three year old girl, like I do, then tree topping is not a viable test for you. The hair on my head is also quite fine; and so on the rare occasion that I feel the need to try an HHT, and for me it is rare, I pluck a chest hair and use that.
Not all hair is the same. For that reason, not all HHTs will perform the same. If your razors shave you well then that is the most important thing. IF you feel the need to keep playing with the HHT, then try out some other hairs!
