This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This report presents the second known case of erythema nodosum without typical associated conditions, which could be linked to mycoplasma infection, although no testing was conducted to confirm this in the patient.

This review discusses hypersensitivity reactions to anticoagulants like ASA and heparins, highlighting their rare but potentially life-threatening nature, and emphasizes the need for meticulous allergy testing to find safe alternatives.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This review discusses the role of skin enzymes in drug metabolism and emphasizes the need for models assessing enzyme activity to evaluate the safety and bioequivalence of topical generic drugs, highlighting efforts to standardize testing protocols for transdermal products.

This study developed a testosterone propionate-induced C57BL/6 mouse model of androgenetic alopecia, demonstrating that high-dose, prolonged testosterone administration inhibited hair regrowth and mirrored human AGA pathology, providing a useful platform for studying hair loss mechanisms and testing therapies targeting the Wnt/β-catenin pathway.

This study suggests that coexisting LSS and TSPEAR variants might contribute to a complex phenotype of congenital hypotrichosis and ectodermal abnormalities in a child, and highlights the need for cautious interpretation of genotype-phenotype links and the potential value of broader genetic testing.

In this study, researchers developed a herbal hair dye using henna and other natural ingredients that achieved a color similar to natural black on blonde hair, though further testing on various hair shades is needed to explore its full benefits.

In this study, a child's diagnosis of Silver-Russell syndrome was confirmed through phenotype data, genetic testing, and the exclusion of other developmental conditions, revealing a need for a multidisciplinary care approach.

This study reports that hair oil formulations using Arnica montana in castor and mustard oil bases showed effective results in quality and quantitative analysis through UV visible spectrophotometer, FTIR, and HPTLC testing methods.

This study describes the successful treatment of erythema multiforme in a young Central American tapir with a combination of wound care, silver sulfadiazine cream, and oral prednisolone, emphasizing the importance of diagnostic testing for vesicular dermatitis syndromes in tapirs.

This study predicted that 6-hydroxy genistein, coreximine, and scoulerine from Dadap leaves may act as anti-alopecia agents by interacting with JAK2, but further in-vivo testing is needed.

This study found that 66% of apparently healthy volunteers had some abnormality on biochemical, hematological, or electrocardiographic testing, highlighting the need for pretreatment evaluations in clinical trials.

The researchers developed a new follicular unit extraction system with adjustable needle lengths and precise rotation speed, which they report as being superior to existing systems for non-incisional hair transplants.

This study found that laboratory testing practices for alopecia areata vary among international hair experts, with the majority routinely conducting thyroid function and complete blood count tests, yet exhibiting diverse approaches toward testing for other conditions or before prescribing systemic therapy.

This study found that keratin-based particles were able to recover and enhance the mechanical properties and thermal stability of virgin and overbleached Asian hair, improving its strength and smoothness by around 40%, and demonstrated safety in human skin keratinocytes.

This review highlights the potential of integrating point-of-care testing with allele-specific amplification techniques like AS-PCR, AS-LAMP, and AS-RPA to improve the efficiency, accuracy, and affordability of genotyping single nucleotide polymorphisms associated with human diseases.

In this study, testing Annurca apple extract on human follicle dermal papilla cells indicated its potential to prevent patterned hair loss by reducing oxidative stress and increasing factors involved in hair growth.

In this study, researchers developed self-assembled skin models derived from hair follicle cells, offering an ethical and reliable alternative to animal testing and bovine collagen in dermatological research by providing functional dermal and epidermal layers for substance evaluation.

This article discusses methods for diagnosing and managing diffuse hair loss and reports no new results; the authors emphasize systematic evaluation and the importance of psychological support.

Human hair follicles can be used to create skin-like tissue for wound healing and drug testing.

This study found that Avicennia marina extract significantly inhibited 5α-reductase type 1 activity in human hair dermal papilla cells, suggesting its potential use for treating androgenic alopecia.

Iron deficiency might cause hair loss, but better testing is needed.

This study reported that the formulated herbal anti-dandruff shampoo demonstrated satisfactory cleansing and conditioning properties, comparable to standard synthetic shampoos, but further testing is needed to confirm its long-term safety.
