Mimicking Natural Human Hair Pigmentation with Synthetic Melanin
ACS Central Science, 2020 Human hair is naturally colored by melanin pigments, which afford myriad colors from black, to brown, to red depending on the chemical structures and specific blends.

Quantitative mapping of human hair greying and reversal in relation to life stress
bioRxiv, 2020 Hair graying is a universal hallmark of chronological and biological aging, but its mechanisms are insufficiently understood and its potential reversibility in humans has not been quantitatively examined.

The biology of human hair greying
Biological Reviews of The Cambridge Philosophical Society, 2020 Hair greying (canities) is one of the earliest, most visible ageing‐associated phenomena, whose modulation by genetic, psychoemotional, oxidative, senescence‐associated, metabolic and nutritional factors has long attracted skin biologists, dermatologists,

Human hair follicle-derived mesenchymal stem cells: Isolation, expansion, and differentiation.
World Journal of Stem Cells, 2020 Hair follicles are easily accessible skin appendages that protect against cold and potential injuries. Hair follicles contain various pools of stem cells, such as epithelial, melanocyte, and mesenchymal stem cells (MSCs) that continuously self-renew ...

Solar ultraviolet protection provided by human head hair [PDF]
, 2009 The solar erythemal UV irradiances through human hair and the protection from UV provided by human head hair have been investigated for a solar zenith angle (SZA) range of 17 to 51 degrees for the conditions of a head upright in full sun, a head upright ...

Journal of Investigative Dermatology, 1970 Hair growth from the vertex, temple, mustache, finger, arm and leg of three Japanese men (60, 30, and 21 years of age) was measured by direct observation from October, 1966 to November 1968. Detailed information regarding hair growth cycles in the regions tested is presented.

Model-based prediction of human hair color using DNA variants [PDF]
, 2011 Predicting complex human phenotypes from genotypes is the central concept of widely advocated personalized medicine, but so far has rarely led to high accuracies limiting practical applications.

Valorization of keratin biofibers for removing heavy metals from aqueous solutions [PDF]
, 2018 Four common waste keratin biofibers (human hair, dog hair, chicken feathers, and degreased wool) have been used as biosorbents for the removal of heavy metal ions from aqueous solutions. Different parameters of the biosorption processes were optimized in

Journal of Investigative Dermatology, 1993 Human hair keratins were among the first to be studied but it is only recently that sufficient information has been obtained to gain a basic biologic perspective of these proteins. Hair keratins are members of the intermediate filament family of proteins, yet are sufficiently divergent from epidermal keratins to warrant separate classification: type Ia

Defining transcriptional signatures of human hair follicle cell states.
Journal of Investigative Dermatology, 2020 The epidermis and its appendage, the hair follicle, represent an elegant developmental system in which cells are replenished with regularity because of controlled proliferation, lineage specification, and terminal differentiation.
