Scalp hair sweating is a significant predictor of hair cortisol levels.
research Effect of constant-release melatonin implants and prolonged exposure to a long day photoperiod on prolactin secretion and hair growth in mouflon (Ovis gmelini musimon)
Melatonin implants and long daylight hours alter the timing of hormone release and hair growth in mouflon sheep.
research Planar cell polarity-dependent and independent functions in the emergence of tissue-scale hair follicle patterns
Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.
research Whole-genome bisulfite sequencing of goat skins identifies signatures associated with hair cycling
DNA methylation changes are linked to hair growth cycles in goats.
research Human Fetal Scalp Dermal Papilla Enriched Genes and the Role of R-Spondin-1 in the Restoration of Hair Neogenesis in Adult Mouse Cells
Certain genes are more active in baby scalp cells and can help grow hair when added to adult mouse skin cells.
research Influence of Chemical Straightening on the Stability of Drugs of Abuse in Hair
Chemical hair straightening significantly reduces detectable drug levels in hair.
research Kinetics and Equilibrium of Solute Diffusion into Human Hair
Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.
research Light Microscopic Hair Abnormalities in Children: Retrospective Review of 119 Cases in a 10-Year Period
Over half of the children had abnormal hair under a microscope, with many having genetic hair conditions.
research Development and validation of rapid and simultaneous method for determination of 12 hair-growth compounds in adulterated products by UHPLC–MS/MS

The new method accurately detects illegal hair-growth drugs in dietary supplements.
research Molecular Regulation and Cellular Heterogeneity in Skin Repair and Hair Follicle Regeneration
Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.
research Sustainable Formulation and Physicochemical Characterization of a Multifunctional Hair Cream Using Natural Ingredients
A natural hair cream with 15% extract is stable, effective, and better for hair and scalp than synthetic creams.
research Ageratum Conyzoides L. Extract Inhibits 5α-Reductase Gene Expression and Prostaglandin D2 Release in Human Hair Dermal Papilla Cells and Improves Symptoms of Hair Loss in Otherwise Healthy Males and Females in an Open Label Pilot Study
Ageratum conyzoides L. extract may effectively and safely treat hair loss.
research Dermal papilla cell number specifies hair size, shape and cycling and its reduction causes follicular decline
More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.
research Lactate dehydrogenase activity drives hair follicle stem cell activation
Lactate production is important for activating hair growth stem cells.
research Hair Growth Cycle Affects Hair Follicle Destruction by Ruby Laser Pulses
Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.
research Cyclosporin A-induced hair growth in mice is associated with inhibition of calcineurin-dependent activation of NFAT in follicular keratinocytes
Cyclosporin A helps mice grow hair by blocking a specific protein activity in skin cells.
research Intravital imaging of hair follicle regeneration in the mouse
Two-photon microscopy helps observe hair follicle stem cell behaviors in mice.
