This study underscores the use of hair analysis in forensic toxicology, highlighting its ability to detect drugs such as opioids and amphetamines, while noting limitations related to hair growth cycles, result interpretation, and cost of techniques.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

This study found that the fungus Microsporum gypseum enzymatically degrades keratin in human hair, with the sequence of degradation reflecting the keratinization and cystine content of individual hair components in vitro.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

This study found that the hair of a 16th-century female mummy discovered in Paju was remarkably well-preserved due primarily to a calcium-based surface coating that likely inhibited moisture and microorganism infiltration.

This study observed that calcifying epithelioma of Malherbe is composed of tumor cells that differentiate into both hair cortex and outer root sheath, supporting its hair follicle origin.

Pollution exposure speeds up hair damage.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

This study found that repeated cycles of wetting and blow-drying hair fibers can cause cracks in the hair cuticles, particularly among individuals who frequently blow-dry their hair.

This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

In this study, researchers found that the morphology, composition, and elemental enrichment of domestic cat hairs vary significantly along their length, contributing to a functional gradient that affects mechanical properties and challenging assumptions of uniformity in hair structure.

This study found that combining photobiomodulation therapy with minoxidil significantly improved hair quality and reduced telogen-phase hair counts more effectively than minoxidil alone in women with female pattern hair loss over a shorter 12.5-week period.

In this study, the authors synthesized recent literature on childhood alopecia areata, highlighting its clinical manifestations and management strategies, which include individualized treatments and psychosocial support to mitigate emotional and social impacts on affected children.

This article reviews treatment options for female-pattern hair loss, noting the limited evidence for most therapies and emphasizing that topical minoxidil remains the only well-supported option despite a significant non-response rate.

This study proposed the existence of a membrane-like structure between the cuticle and cortex in human hair, which may provide strong protection against external stimuli.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study found that using a ruby laser for hair removal resulted in a significant average reduction of 56.4% in hair density among participants dissatisfied with other methods.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This study investigated the effects of 10600nm CO2 dot laser and Nd: YAG laser on Wistar rats' skin, finding that CO2 laser treatment resulted in higher positive expression of MMP-1 and TIMP-1 compared to Nd: YAG laser, with statistically significant differences noted.

This study observed that long-term laser hair removal in women may alter hair follicle structures and stem cell interactions, with dermal fibrosis potentially influencing hair regrowth prevention.

This study suggests that a 1,550-nm fractional erbium-glass laser may stimulate hair growth in both an alopecia mouse model and human subjects with male pattern hair loss, though further research is needed to determine its clinical applications.

This study found that combining ablative fractional CO₂ laser therapy with hair growth factors significantly increased hair density in men with androgenetic alopecia compared to using growth factors alone.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This study found that the aqueous ethanol extract of Myricae Cortex demonstrated in vitro testosterone 5alpha-reductase inhibitory activity and in vivo anti-androgenic effects in mouse and hamster models.
