,
February 2013 in “The American Journal of Dermatopathology” This study found that follicular density and various hair growth ratios differ statistically between nonscarring and scarring alopecia, though significant overlap exists due to factors like sample size and scalp variation.

,
September 1997 in “Dermatologic Surgery” This study found that mini-micrografting and plug methods achieve comparable hair density, but mini-micrografting requires fewer sessions due to its dense graft packing.
13 citations
,
March 2006 in “International Journal of Cosmetic Science” The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
4 citations
,
April 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” This study estimates that approximately 230,000 tactile afferent fibers innervate the human body's skin, with varying densities across different regions correlating with spatial acuity and hair follicle density.
