research Androgens and hair growth
Androgens can both increase and decrease hair growth in different parts of the body.
research Hair follicle differentiation and regulation.
Hair follicle growth and development are controlled by specific genes and molecular signals.
research Tactile innervation densities across the whole body
Young adults have about 230,000 tactile nerve fibers, decreasing 5-8% per decade with age.
research Human hair follicle organ culture: theory, application and perspectives
Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.
research Biochemical and trichological characterization of diffuse alopecia in women
Diffuse alopecia in women may be related to androgens and iron deficiency, and basic hormone and nutrient screening is useful.
research Hormonal regulation of hair follicles exhibits a biological paradox
Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.
research Whole-genome sequencing of eight goat populations for the detection of selection signatures underlying production and adaptive traits
Researchers identified genes linked to coat color, body size, cashmere production, and high altitude adaptation in goats.
research Practical whole-tooth restoration utilizing autologous bioengineered tooth germ transplantation in a postnatal canine model
Bioengineered tooth germ can restore whole teeth in dogs.
research Trans‐species hair growth induction by human hair follicle dermal papillae
Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.
research What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women
Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.
research The impact of oxidative stress on hair
Oxidative stress damages hair and contributes to aging, and managing it can help maintain hair health.
research The effects of minoxidil, 1% pyrithione zinc and a combination of both on hair density: a randomized controlled trial
Minoxidil and pyrithione zinc combo most effectively increases hair density.
research Finasteride for female androgenetic alopecia
Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.
research Changing the shape of hair with keratin peptides
Keratin peptides can change hair shape gently without harsh chemicals.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research Induction of hair follicle dermal papilla cell properties in human induced pluripotent stem cell-derived multipotent LNGFR(+)THY-1(+) mesenchymal cells
Researchers found a way to create cells from stem cells that act like human cells important for hair growth and could be used for hair regeneration treatments.
research Hair through the female life cycle
Women's hair generally gets thinner and less dense starting in their mid-thirties, with hair loss becoming more common as they age due to both genetics and environment.
research Critical study of hair growth analysis with computer-assisted methods
The Trichoscan system was found to be inaccurate for measuring hair growth, needing better software to be useful.
research Hormonal changes in menopause: do they contribute to a ‘midlife hair crisis’ in women?
Menopause-related hormonal changes affect hair but are not the only cause of hair changes in middle-aged women.
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research Early onset and novel features in a spinal and bulbar muscular atrophy patient with a 68 CAG repeat
A patient with a larger than usual genetic mutation had a broader range of symptoms for a muscle disease.
research Cyclical Changes in Rat Vibrissa Follicles Maintained In Vitro
Rat vibrissa follicles are useful for studying hair growth cycles, especially the transition from pro-anagen to anagen.
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research The clinical management of hirsutism
The document concludes that managing hirsutism involves identifying the cause, using a scoring system for severity, combining cosmetic and medical treatments, encouraging weight loss, and providing psychological support, while noting the need for more research on drug treatments.
research Protein disulphide isomerase-mediated grafting of cysteine-containing peptides onto over-bleached hair
PDI helps restore over-bleached hair's strength and structure by attaching special peptides.
research Immune cell regulation of the hair cycle
Immune cells affect hair growth and could lead to new hair loss treatments.
research Measurement of hair growth
Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Hair care practices and structural evaluation of scalp and hair shaft parameters in African American and Caucasian women
African American women report more hair issues and use different hair care practices than Caucasian women, and have different hair and scalp characteristics.
