research Assessment of hair loss: clinical relevance of hair growth evaluation methods
Effective hair loss assessment requires a mix of precise measurement methods.
research Androgenic Alopecia: Cross-Talk Between Cell Signal Transduction Pathways
Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
research Diversity of hair growth profiles
Different ethnic groups have unique hair growth patterns, with African hair growing slower and less dense, Asian hair growing fast but sparse, and Caucasian hair being densest; men are more likely to experience hair loss than women.
research Microneedles mediated bioinspired lipid nanocarriers for targeted treatment of alopecia
A new hair loss treatment uses tiny needles to deliver a drug-loaded lipid carrier, promoting hair growth more effectively than current treatments.
research Anagen hair follicle repair: Timely regenerative attempts from plastic extra‐bulge epithelial cells
Certain cells outside the hair follicle's bulge area can quickly regenerate damaged hair follicles, potentially helping to reduce hair loss from cancer treatments.
research Evaluation of wavelength-dependent hair growth effects on low-level laser therapy: an experimental animal study
The 830-nm wavelength was most effective at promoting hair growth in rats using low-level laser therapy.
research Diagnostic challenge: Loose anagen hair syndrome
The study concludes that Loose Anagen Hair Syndrome is a benign condition that usually improves with age but can be hard to diagnose and stressful for the family.
research Does the Recipient Site Influence the Hair Growth Characteristics in Hair Transplantation?
The recipient site can affect the growth and survival of transplanted hair but not its thickness.
research Physiological and biological skin changes in pregnancy
Pregnancy causes skin changes like darkening, hair thickening, nail changes, and increased risk of skin growths, most of which usually resolve after birth.
research Over-expression of thymosin beta4 promotes abnormal tooth development and stimulation of hair growth
Too much thymosin beta4 causes weird teeth and more hair growth in mice.
research TELOGEN EFFLUVIUM: AN ETIOPATHOGENETIC THEORY
The paper suggests that telogen effluvium, a type of hair loss, may be a long-lasting condition triggered by stress or illness in people whose hair growth is unusually synchronized.
research Efficacy and Safety of a Food Supplement Containing L-cystine, Serenoa repens Extract and Biotin for Hair Loss in Healthy Males and Females. A Prospective, Randomized, Double-blinded, Controlled Clinical Trial
The food supplement with L-cystine, Serenoa repens extract, and biotin safely reduced hair loss and improved hair growth in men and women.
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 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 The Administration of Flumethasone, by Three Different Routes, its Measurement in the Plasma and Some Effects on Wool Growth in Merino Wethers
Flumethasone causes wool shedding in Merino wethers, with recovery in about 60 days.
research Seasonal variation in hair follicle activity and fibre growth of both male and female Merghoz goats in Western Iran
Goat hair growth and follicle activity change with the seasons and differ between males and females.
research Evaluation of platelet‐rich plasma plus basic fibroblast growth factor combined with minoxidil in the treatment of androgenetic alopecia: A randomized controlled trial
Using platelet-rich plasma, basic fibroblast growth factor, and minoxidil together significantly increases hair count and growth rate in people with hair loss.
research Potential targets in the discovery of new hair growth promoters for androgenic alopecia
The document concludes that targeting 5α-reductase, the androgen receptor, and hair growth genes, along with using compounds with anti-androgenic properties, could lead to more effective hair loss treatments.
research Induction of Hair Growth by Insulin-Like Growth Factor-1 in 1,763 MHz Radiofrequency-Irradiated Hair Follicle Cells
Radiofrequency exposure can stimulate hair growth by increasing IGF-1 in hair follicle cells.
research Safety of low‐dose oral minoxidil treatment for hair loss. A systematic review and pooled‐analysis of individual patient data
Low-dose oral minoxidil is a safe treatment for hair loss, with the main side effect being excessive hair growth. Other side effects like foot swelling, low blood pressure when standing, and heart rate changes are rare.
research KF19418, a new compound for hair growth promotion in vitro and in vivo mouse models
KF19418 promotes hair growth similarly to minoxidil but is not better in live mice.
research Commentary on Autologous Platelet-Rich Plasma: A Potential Therapeutic Tool for Promoting Hair Growth
Platelet-rich plasma (PRP) may help promote hair growth and improve graft survival after hair transplantation, but more research is needed to confirm its effectiveness and determine the best dosage.
research Combination of Candlenut (Aleurites mollucana (L.) Wild) Oil and Celery (Apium graveolens) Extract Stimulates Hair Growth: Formulation and Activity Test of Spray Preparation
Celery extract and candlenut oil effectively and safely boost hair growth.
research Cellular Activity in the Dermis Surrounding the Hair Bulb in Alopecia Areata
Hair growth in alopecia areata is hindered due to impaired cell activity in the surrounding tissue.
research Thrombospondin-1 Plays a Critical Role in the Induction of Hair Follicle Involution and Vascular Regression During the Catagen Phase
Thrombospondin-1 is crucial for hair follicle regression and reduced blood vessel growth during the catagen phase.
research Hair Loss in Systemic Disease
Systemic diseases can cause hair loss, which is often reversible with treatment.
research Integrated analysis of coding genes and non-coding RNAs during hair follicle cycle of cashmere goat (Capra hircus)
The study improved understanding of gene roles in cashmere goat hair growth, aiding future cashmere production.
research β-Catenin is involved in oleanolic acid-dependent promotion of proliferation in human hair matrix cells in an in vitro organ culture model
Oleanolic acid promotes hair growth by increasing cell proliferation through the Wnt/β-catenin pathway.
research Hair Loss Physiology and Transplantation Principles
Hair loss is caused by hormonal changes that shorten hair growth phases and shrink hair follicles.
