This study shows that multiphoton microscopy can non-invasively distinguish between scarring and non-scarring alopecia by identifying certain morphological features, but further research is needed to confirm its clinical utility.

This study explored the dermal stem cell niche of equine hair follicles, revealing typical fibroblast morphology and confirming the expression of standard stem cell markers comparable to other species.

This study observed that individuals with mixed ethnicity had hair that varied widely in shape and showed significant surface damage near the root, differing from monoracial hair characteristics.

This retrospective review of hair samples from pediatric patients indicated that microscopic hair examination might be a useful first-line investigation for diagnosing various genetic conditions.

This study found that an enzymatic method effectively identified chemical treatments like perming and dyeing by detecting higher degradation in treated hair compared to untreated hair.

This review discusses the epidemiology, causes, diagnosis, and management of hirsutism in women, noting that effective treatment requires addressing the root cause as well as the hair growth.

This study found significant differences in the spread of sebum on hair among Chinese men with greasy and non-greasy scalps, despite similar sebum amounts at the root region post-shampoo.

This study developed a new melanocyte cultivation medium without chemical mitogens, melanogenesis enhancers, or bovine products, demonstrating successful proliferation and melanotic differentiation of human melanocytes from hair follicles.

This study used light sheet fluorescence microscopy to successfully image and analyze calcium oscillations in the root hairs of Arabidopsis thaliana, finding that these oscillations correlate with the root hair growth rate and that auxin affects these properties.

This review summarizes major growth factors that promote hair follicle growth, but it reports no new experimental findings.

This study found that specific DNA variants in the TCHH, WNT10A, and FRAS1 genes are associated with predicting straight hair in Europeans, showing high sensitivity but low specificity, especially using a neural networks approach.

Escin helps keep hair follicles in the growth phase longer.

In this study, researchers observed that inoculation with Funneliformis mosseae significantly enhanced growth, biomass, and root architecture in trifoliate orange plants, with variations in auxin levels and gene expression, suggesting PtPIN6 as a key gene involved in root hair development regulation.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.

This study reports the successful generation of inducible pluripotent stem cells from mesenchymal stem cells derived from human hair follicles, marking a novel method of reprogramming these cells.

Eating isoflavone can help mice grow hair by increasing a growth factor.

This study found that both Japanese male and female hair darkens with age, with significant sex differences in melanin composition and melanosome morphology influencing hair color.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This study successfully cultured human fetal hair follicle-derived melanocytes, which showed high proliferative capabilities and unique morphological characteristics compared to adult-derived cells, potentially advancing hair disease research.

Pigs are a good model for studying human hair growth and disorders.

This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

This study observed that antisense oligonucleotides targeting FGFR-1 increased cellular activity in hair follicle cultures from mice, suggesting potential clinical utility for treating baldness.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This study found that transthyretin and megalin expression in human scalp hair follicles varies significantly with the hair growth cycle, peaking during anagen and diminishing in catagen and telogen phases.

This study identifies iRhom2 as a crucial regulator of hair follicle differentiation, showing that the iRhom2Uncv mutation leads to dysplasia and reduced TACE maturation, resulting in a hairless phenotype in mice.

This study found that in Arabidopsis root hairs, oscillating cytoplasmic potassium dynamics precede growth oscillations, suggesting a complex interplay with calcium signaling and microfilament structure in regulating root hair growth.

This study found that a combination of Trichogen and climbazole may inhibit protease activity and increase the force required to remove human hair, suggesting potential to reduce excessive hair shedding.

The document explains what healthy skin, nails, and hair look like on an ultrasound.

This study suggests that the hydrogel nanoparticle formulation of hair growth-promoting compounds may enhance hair follicle penetration and induce hair growth in tested models, demonstrating its potential as a hair growth treatment.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.
