research Quantitative Models for the Study of Hair Growth in Vivoa
The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.
research Evaluation of Hair Density and Hair Diameter in the Adult Thai Population Using Quantitative Trichoscopic Analysis
Thai people's hair density decreases with age and varies by scalp area, but hair thickness stays the same regardless of age or scalp area.
research PI3K/Akt signaling pathway is essential for de novo hair follicle regeneration
PI3K/Akt pathway is crucial for hair growth and regeneration.
research Finasteride is the main inhibitor of 5α-reductase activity in microdissected dermal papillae of human hair follicles
Finasteride potentially treats hair loss by reducing DHT production.
research Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers
Pollution exposure speeds up hair damage.
research Analysis of Dermal Papilla Cell Interactome Using STRING Database to Profile the ex Vivo Hair Growth Inhibition Effect of a Vinca Alkaloid Drug, Colchicine
Colchicine can inhibit hair growth by affecting cell activity and protein expression in hair follicles.
research A 3-Month, Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Ability of an Extra-Strength Marine Protein Supplement to Promote Hair Growth and Decrease Shedding in Women with Self-Perceived Thinning Hair
An extra-strength marine protein supplement helped increase hair growth and decrease hair shedding in women with thinning hair.
research Miniaturized hairs maintain contact with the arrector pili muscle in alopecia areata but not in androgenetic alopecia: A model for reversible miniaturization and potential for hair regrowth
Miniaturized hairs stay connected to muscle in alopecia areata, allowing possible regrowth, but not in androgenetic alopecia.
research Hair growth control by innate immunocytes: Perifollicular macrophages revisited
Immune cells around hair follicles help control hair growth and could be targets for treating hair disorders.
research Contribution of hair density and hair diameter to the appearance and progression of androgenetic alopecia in Japanese men
Hair thickness matters more than density for baldness in Japanese men over 25.
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

research 3D printing of microneedle arrays for hair regeneration in a controllable region
3D-printed microneedles can precisely regrow hair in targeted areas.
research Thiolated and PEGylated silica nanoparticle delivery to hair follicles
Using longer PEG chains helps nanoparticles penetrate hair follicles better, improving drug delivery for conditions like alopecia.
research Clinical relevance of hair microscopy in alopecia
Hair microscopy is useful for diagnosing certain hair loss conditions but has limitations and must be interpreted carefully.
research Association of Hair Loss With Health Utility Measurements Before and After Hair Transplant Surgery in Men and Women
Hair loss greatly lowers perceived health in both genders, and hair transplant surgery notably improves this.
research Titrated extract ofCentella asiaticaincreases hair inductive property through inhibition of STAT signaling pathway in three-dimensional spheroid cultured human dermal papilla cells
Centella asiatica extract may help promote hair growth by blocking a specific cell signaling pathway.
research In Vitro Methodologies to Evaluate the Effects of Hair Care Products on Hair Fiber
Different tests are used to see how hair care products affect hair, and choosing the right test is important for accurate results.
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.
