In situ DNA labeling in hair can help predict forensic DNA analysis success.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Splitting Hairs: Evaluating the Origin of Human Nakedness
Humans likely became hairless to better regulate body temperature.
research Ultramicroscopic study on the hair of newly found 15th century mummy in Daejeon, Korea
The 15th-century Korean mummy's hair was well-preserved due to a protective lime-soil coating.
research 811 Mitochondrial MPZL3 in the inner root sheath regulates human hair follicle cycling ex vivo
MPZL3 protein affects hair growth cycles and could help manage hair loss.
research Unraveling the Strand: A Comprehensive Review on the Forensic Significance of Microscopic Human Scalp Hair Analysis
Microscopic hair analysis is important in forensics but has limitations; new technologies are improving its accuracy.
research Dermatologic Features of Classic Movie Villains
Most classic movie villains have skin conditions, unlike the heroes, which may cause bias against real people with similar conditions.
research How Should Educators and Publishers Eliminate Racial Essentialism?
Educators and publishers should focus on teaching racism as the cause of health inequity and ensure fair use of race in materials.
research Short sequence repeats of the intergenic spacer regions of ribosomal RNA genes in Malassezia globosa and M. restricta colonizing the scalps of male individuals with and without androgenetic alopecia
A specific DNA pattern in Malassezia restricta may be linked to hair loss in men.
research 1340 Basal keratinocytes exhibit age-related epigenetic and transcriptomic alterations resulting in an altered metabolic profile
Aging changes skin cells, leading to different DNA methylation and gene activity, affecting cell metabolism and aging signs.
research Regulation of somatic cell reprogramming through inducible mir-302 expression
Increasing mir-302 turns human hair cells into stem cells by changing gene regulation and demethylation.
research Establishment and characterization of matched immortalized human frontal and occipital scalp dermal papilla cell lines from androgenetic alopecia
Scientists created cell lines from balding patients and found that cells from the front of the scalp are more affected by hormones that cause hair loss than those from the back.
research Priming mobilization of hair follicle stem cells triggers permanent loss of regeneration after alkylating chemotherapy
Chemotherapy causes permanent hair follicle damage by triggering stem cell loss.
research Hair follicle stem cell replication stress drives IFI16/STING-dependent inflammation in hidradenitis suppurativa
Stress in hair follicle stem cells causes inflammation in a chronic skin condition through a specific immune response pathway.

A new hair transplant method suggests freezing and storing dense hairs for future use to address severe hair loss.
research Resting no more: re‐defining telogen, the maintenance stage of the hair growth cycle
The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
