This review highlights the light microscopic features of various infectious and non-infectious hair conditions and reports no new clinical results.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

This study reports that Elvitegravir, a drug currently approved for other uses, shows potential as a neuro- and mitoprotective agent by attenuating mitochondrial damage caused by NMDA receptors in primary mouse cortical neurons.

This study found that combining optical clearing methods with light-sheet fluorescence microscopy allows detailed 3D visualization of normal and pathological human skin biopsies, revealing differences in epidermal thickness and volume.

This review highlights that laser and light treatments could serve as safe and effective alternatives to current therapies for alopecia areata, with the excimer laser showing positive results, though further randomized controlled trials are necessary to establish optimal treatment protocols.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

This study used in vivo confocal microscopy and a ResNet34 deep learning model to classify meibomian gland images with an AUROC greater than 0.95, indicating its potential for automatic diagnosis and screening of meibomian gland dysfunction.

This study reported that a low color temperature light (1900 K) may have positive effects on melatonin secretion, eye protection, wound healing, and hair regeneration compared to higher temperature lights.

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 found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

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

This study presented a new wearable textile-based device with near-infrared OLEDs that significantly reduced cell aging markers and improved cell migration in vitro, suggesting it as a promising, non-invasive phototherapy option for hair follicle treatment and hair-loss management.

In this study, researchers suggest that digital microscopy using visible light could offer a more objective approach to diagnosing hirsutism by quantifying terminal hair, with future research needed to assess its usefulness in women with the condition.

This study concluded that while home-based intense pulsed light, laser diodes, radiofrequency, and light-emitting diode devices are recommended for certain skin conditions, ultraviolet B phototherapy for psoriasis showed mixed evidence compared to clinic treatments.

This review suggests that paradoxical hair growth after light-based treatments is unlikely due to the devices themselves; instead, it may be linked to other factors such as inflammation in individuals with certain conditions.

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 study found that the multifunctional FEA-PCEI dressing significantly accelerated wound healing, reduced scar formation, and promoted hair follicle neogenesis while providing antibacterial and anti-inflammatory benefits.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

This study concluded that combining the Shumin treatment instrument with oral doxycycline provides better clinical outcomes for rosacea than combining red light therapy with doxycycline, while both regimens improved quality-of-life scores and reduced Demodex counts.

In this study, researchers investigated a new local drug delivery system using glycol chitosan hydrogel and doxorubicin (GC10/DOX) for thyroid cancer in mice, finding it produced a stronger antitumor effect compared to conventional treatment methods.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

A new method helps understand hair shine and various products improve hair care.

This study found that intracorneal vacuoles were common in various parakeratotic skin diseases in dogs, but large vacuoles were exclusively observed in congenital follicular parakeratosis.

This article reviews various diagnostic tools for hair disorders, describing methods ranging from invasive to noninvasive, but reports no new research findings or clinical results.

This review discusses the role of scalp imaging techniques in trichology for researching drug delivery and toxicology, without presenting new clinical results.

This article reviews the clinical and diagnostic features of hair shaft disorders, emphasizing the role of structured patient assessments and the avoidance of hair trauma, but reports no new results.
