Why Thick Coarse Hair Breaks on the Wrong Tool
Coarse hair has a wider diameter per strand than fine hair, which means more surface area for a bristle or tooth to catch on. When a tool with tight spacing meets hair that is dense and dry, it does not glide, it grabs, and the strand either stretches past its elastic limit or snaps at a weak point. The damage looks like breakage at the mid-shaft, not at the tip, which is the tell that the tool, not the ends, is the problem.
