research Reductive Stress Selectively Disrupts Collagen Homeostasis and Modifies Growth Factor-independent Signaling Through the MAPK/Akt Pathway in Human Dermal Fibroblasts
Reductive stress messes up collagen balance and alters cell signaling in human skin cells, which could help treat certain skin diseases.
research The solar window hypothesis: androgenetic alopecia as an evolutionary adaptation to maintain bone mineral density in vitamin D receptor low-efficiency variants
research Androgenic Alopecia and Stress-Induced Premature Senescence by Cumulative Ultraviolet Light Exposure
Chronic exposure to sunlight may worsen male pattern baldness and protecting the scalp from the sun could slow it down.
research 517 Regulation of the lipidome and lipid metabolism in prematurely senescent human dermal fibroblasts
Aging skin cells change their lipid profiles due to stress, affecting skin health.
research Human Hair Follicle and Epidermal Melanocytes Exhibit Striking Differences in Their Aging Profile which Involves Catalase
Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.
research Skin, hair and beyond: the impact of menopause
Menopause causes dry skin, wrinkles, and hair changes, with hormone therapy helping but not recommended just for these issues.
research Microbes, ferments and moulds /
research Function and underlying mechanisms of seasonal colour moulting in mammals and birds: what keeps them changing in a warming world?
Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.
research Bio-Catalytic Action of Pseudomonas DL17 on Environmental Contaminant Sunset Yellow FCF
Pseudomonas DL17 can completely break down the harmful dye Sunset Yellow FCF in 48 hours.
research Erosive pustular dermatosis of the scalp successfully treated with oral prednisone and topical tacrolimus
Scalp condition healed with prednisone and tacrolimus.
research Aging, alopecia, and stem cells
The document concludes that both internal stem cell factors and external influences like the environment and hormones affect hair loss and aging, with potential treatments focusing on these areas.

research Characterization and causal investigations of an alopecia syndrome in Australian fur seals (Arctocephalus pusillus doriferus)
Young female Australian fur seals are losing hair due to low tyrosine and zinc levels and high pollution exposure.
research Three Streams for the Mechanism of Hair Graying
Hair graying may be caused by stem cell depletion from stress or melanocyte damage.
research A Multi-Technique Approach to the Study of Structural Stability and Desolvation of Two Unusual Channel Hydrate Solvates of Finasteride
Desolvation of finasteride depends on environment and technique.
research Integrated chemometric fingerprints of antioxidant activities and HPLC–DAD–CL for assessing the quality of the processed roots of Polygonum multiflorum Thunb. (Heshouwu)

research Effect of Waste Human Hair Fibers on Shear Behavior of Sand in Dry and Saturated Conditions
Adding human hair to sand improves its strength when dry and maintains strength when wet.
research Towards a “free radical theory of graying”: melanocyte apoptosis in the aging human hair follicle is an indicator of oxidative stress induced tissue damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Single Root hair growth under constant force: insights into wall mechanics
Root hair growth slows under force, confirming a model of cell wall mechanics.
