In this study, pantothenic acid at 20 μg/ml was observed to promote dermal papilla cell proliferation and migration, likely through up-regulation of ID3 and inhibition of Notch signaling.

Men with pattern baldness may have a higher risk of prostate issues.

This study suggests that the anchorage of the arrector pili muscle to the extracellular matrix is likely mediated by α5β1 integrin, with α1β1 integrin involved in muscle cell-cell adhesion.

Polarized microscopy is a quick and free method to correctly identify types of hair loss.

This study observed that including cationic minoxidil particles in a shampoo facilitated notable hair growth promotion despite a negative surface charge after rinsing, likely due to ionic interactions with the skin.

This study observed that methylene blue, a mitochondrial-targeted antioxidant, promotes hair follicle stem cell proliferation and viability through reduced oxidative stress and enhanced β-catenin signaling, and it may also protect against hair loss related to glucagon-like peptide-1 receptor agonists by reducing metabolic stress.

This article discusses themes in the molecular structure of hair and reports no new research findings.

This study found that amphetamine was preferentially incorporated into black hair compared to white hair in Long-Evans rats, suggesting a role for drug basicity in hair color-based drug incorporation.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

Certain genes influence the direction of hair whorls on the scalp.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

In this study, researchers used three-dimensional reconstruction to show that the shape of the hair follicle determines the hair's form, with variations observed among different racial groups.

This study used hair samples to assess mineral levels and found that higher iron status may be associated with an increased risk of esophageal squamous cell carcinoma, while no significant associations were observed for copper and magnesium levels in this cohort.

This study analyzes contemporary theories and practices to understand key factors influencing the development of the examined phenomenon, proposing trends and practical applications for researchers and practitioners, while acknowledging study limitations and suggesting future research directions.

This case report describes an 11-month-old boy with Menkes disease, highlighting symptoms such as developmental delays and poor therapeutic response due to significant brain and vascular abnormalities.

This study demonstrates that MPM-FLIM multimodal imaging can effectively assess the delivery and dissolution of zinc pyrithione particles in human skin follicles using different application techniques.

In this study, the researchers explored how the loss of structural integrity in hair follicles due to reduced α-SMA expression in the vertex area may contribute to androgenetic alopecia.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

This study presents male pattern androgenetic alopecia (mpAGA) as a natural physiological process involving reversible transformation of hair follicles, but notes unresolved links with androgen mechanisms and highlights potential research avenues beyond androgen receptor signaling for treatment exploration.

This review discusses triboelectric nanogenerator (TENG) devices for body-integrated electrical stimulation therapy and suggests they may revolutionize personalized healthcare, but it reports no new clinical results.

This study reported that a new two-point bending stiffness method effectively correlated with sensory assessments for hair styling gels but not for hair styling sprays, likely due to differences in polymer/hair composites.

This study found that an extracellular calcium binding site gradient exists in mouse vibrissa and human scalp follicles, but is not significantly affected by hair growth-altering drugs or epidermal growth factor.

This study found that low power He:Ne laser and methylene blue successfully damaged hair follicles in mice while preserving the epidermis, suggesting a potential for improved long-term hair removal options.

This study found a higher frequency of below normal ferritin and serum iron levels in women with melasma compared to controls, suggesting a possible association with melasma.

In this study, researchers assessed magnesium intake in women aged 40 to 65 across urban Bangalore, finding it below the Recommended Dietary Allowance and noting deficiencies associated with symptoms like hair loss and muscle cramps. Biochemical assessment was recommended to confirm these findings.

This study suggests that male pattern baldness is primarily caused by heat stress in the brain rather than DHT toxicity, and personal experiments with menthol cooling have shown significant reduction in hair loss.

This article discusses the Doppler effect as illustrated by the sound of a passing police siren but presents no new research findings.
