Unfortunately it depends on the hair you choose. I recommend getting a chest hair or other "firm/stiff" hair for these tests not hair from your head. That won't work well. This is why we recommend buying a sharp razor from a member first, for a benchmark. To try testing like the HHT or looking at them in a microscope before ever shaving with them.

You may have to resort to shave testing, which is not too big a deal but you can cause some pretty serious irritation that way.

I would never shave with a razor that doesn't pass the HHT for my hair.
