research Herbal Extracts Induce Dermal Papilla Cell Proliferation of Human Hair Follicles
Herbal extracts may help hair grow and could be an alternative to synthetic hair loss treatments.
research Nutritional factors and hair loss
Low iron and L-lysine levels can cause hair loss in women, and increasing these nutrients can reduce hair shedding.
research Bacillus/Trapa japonica Fruit Extract Ferment Filtrate enhances human hair follicle dermal papilla cell proliferation via the Akt/ERK/GSK-3β signaling pathway
The extract from Bacillus/Trapa japonica fruit helps increase hair growth and could be a potential treatment for hair loss.
research Charge density alterations in human hair fibers: an investigation using electrostatic force microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research Clinical Management of Youth with Gender Dysphoria in Vancouver
Most youth with gender dysphoria received hormones, had minor complications, and showed a decrease in suicide attempts after treatment.
research Regenerative Hair Waves in Aging Mice and Extra-Follicular Modulators Follistatin, Dkk1, and Sfrp4
Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.
research Estrogens and the hair follicle. Ostrogene und der Haarfollikel
Estrogens generally inhibit hair growth and improve skin quality, but their exact effects on hair follicles are complex and not fully understood.
research Identification of Ectodysplasin Target Genes Reveals the Involvement of Chemokines in Hair Development
Chemokine signaling is important for hair development.
research Contribution of the Hair Follicular Pathway to Total Skin Permeation of Topically Applied and Exposed Chemicals
The hair follicle pathway significantly affects how easily water-loving chemicals pass through the skin.
research The effect of tripeptide-copper complex on human hair growth in vitro
A tripeptide-copper complex may help hair grow by increasing cell growth and decreasing cell death.
research A role of placental growth factor in hair growth
Placental growth factor may help treat hair loss.
research Intradermal injections of a hair growth factor formulation for enhancement of human hair regrowth – safety and efficacy evaluation in a first-in-man pilot clinical study
The QR 678 hair growth treatment was safe and effective for hair regrowth in men and women.
research iRhom2 Mutation Leads to Aberrant Hair Follicle Differentiation in Mice
A mutation in the iRhom2 gene causes hairless mice due to abnormal hair follicle development.
research Effects of a new mild shampoo for preventing hair loss in Asian by a simple hand-held phototrichogram technique
The new mild shampoo helped prevent hair loss in the subjects.
research The impact of different hair‐removal behaviours on the biophysical and biochemical characteristics of female axillary skin
All hair removal methods irritate underarm skin and cause dryness, with shaving being less irritating but more drying than plucking or waxing.
research Rhomboid Minigrafts in Hair Restoration Surgery
Rhomboid-shaped minigrafts, measuring 1.5 x 1.5 mm, lead to fewer complications and better results in hair restoration surgery compared to square or rectangular ones.
research Effects of oral minoxidil on serum VEGF and hair regrowth in androgenetic alopecia
Oral minoxidil boosts hair growth and reduces shedding in androgenetic alopecia.
research MicroRNA-205 promotes hair regeneration by modulating mechanical properties of hair follicle stem cells
MicroRNA-205 helps hair grow by changing the stiffness and contraction of hair follicle cells.
research The effect of relative humidity on the spreading of ethanol on human hair fibers
Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.
research Effects of Sex Steroid Deprivation/Administration on Hair Growth and Skin Sebum Production in Transsexual Males and Females
Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.
research Androgens and androgen receptor action in skin and hair follicles
Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.
research CRISPR/Cas9-mediated Disruption of Fibroblast Growth Factor 5 in Rabbits Results in a Systemic Long Hair Phenotype by Prolonging Anagen
Disrupting the FGF5 gene in rabbits leads to longer hair by extending the hair growth phase.
research miR‐218‐5p regulates skin and hair follicle development through Wnt/β‐catenin signaling pathway by targeting SFRP2
miR-218-5p helps skin and hair growth by targeting SFRP2 and activating a specific signaling pathway.
research Hair Transplantation in Migraine Headache Patients
Some migraine sufferers had no more headaches after getting a hair transplant.
research Fgf9 from dermal γδ T cells induces hair follicle neogenesis after wounding
A protein from certain immune cells is key for new hair growth after skin injury in mice.
research Sustained release of dermal papilla-derived extracellular vesicles from injectable microgel promotes hair growth
Injecting a special gel with human protein particles can help hair grow.
research Human placental extract exerts hair growth-promoting effects through the GSK-3β signaling pathway in human dermal papilla cells
Human placental extract may help hair growth by affecting certain cell signals and could be more effective with minoxidil.
research The Contributory Roles of Th17 Lymphocyte and Cytotoxic T Lymphocyte at the Hair Bulge Region as Well as the Hair Bulb Area in the Chronic Alopecia Areata Patients
Certain immune cells contribute to severe hair loss in chronic alopecia areata, with Th17 cells possibly having a bigger impact than cytotoxic T cells.
research The effects of extended photoperiod and warmth on hair growth in ponies and horses at different times of year
Timing of light therapy affects horse coat growth, with photoperiod being crucial.
