Hairs per cm^2 is one metric (per the mentioned numbers) an 11% increase. By ridiculous, I presume a connotation of "not material" or "not worth the effort" (and for some, it isn't, because they don't respond to the treatment). Returning to metrics, another could be the diameter of each hair, which impacts the aesthetic quality. 151 hairs per cm^2 doesn't visually present the same for all individuals with that exact density (due to thinness/thickness of each follicle). Other treatments can be paired with it simultaneously, which may further improve results.
