In this study, hirsute women with normal or medically normalized testosterone levels experienced similar, though declining, hair reduction from both intense pulsed light and long-pulsed diode laser treatments over six months.

This review discusses various physical treatments for unwanted hair, including the use of lasers and light sources, but reports no new clinical findings.

Red and infrared light therapy improves hair growth in balding patients.

This review discusses the applications of the 308-nm excimer laser in treating various dermatologic conditions and suggests treatment is generally well tolerated, but calls for larger long-term studies.

In this study, low-dose 453 nm blue light appeared to enhance hair growth by interacting with specific photoreceptors in the outer root sheath cells.

This review examined photothermal hydrogels, biomedically innovative materials responsive to near-infrared stimulation, which hold promise for enhancing infection control and tissue regeneration. The authors highlighted their unique properties, construction methods, and potential applications while also discussing existing challenges and future research directions.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study reported that the PrrH sRNA in *Pseudomonas aeruginosa* may directly regulate genes involved in pyochelin siderophore biosynthesis, highlighting its role in adapting to heme availability, with light conditions influencing this gene expression.

This study suggests that PF-0998425 is an effective androgen receptor antagonist for sebum control and androgenetic alopecia with rapid metabolism reducing the risk of systemic side effects.

This study observed that post-surgical use of chlorhexidine digluconate mouth rinse in patients may induce a fibrotic transformation in gingival tissue, promoting a scar-like wound healing response.

This study developed ultrasound-responsive sutures that generate reactive oxygen species to kill bacteria without antibiotics, showing over 80% bacterial reduction and promoting healing in a rat model, though more validation is needed.

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 found that combining flutamide with an oral contraceptive significantly reduced hirsutism, acne, and seborrhea in patients after seven months, without significant side effects.

In this study, Wood's lamp effectively identified tinea capitis among pediatric patients with alopecia, particularly when contact with animals was a factor, supporting its diagnostic use in primary healthcare settings.

In this study, a new IPL device effectively reduced hair regrowth with high patient satisfaction, particularly in individuals with coarse dark hair and darker skin, despite repeated sessions needed for lighter hair and skin.

Among participants in a 26-week trial, this study by REVIAN Inc. reported that their REVIAN RED dual wavelength LED light treatment for androgenetic alopecia was both safe and effective at the 16-week mark.

This study investigated the effects of heat-treated Limosilactobacillus fermentum LM1020 on hair growth and reported increased hair density, improved cellular activity, and beneficial scalp microbiota changes in patients with androgenetic alopecia over 24 weeks.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This study reports that electromagnetic energy from a hydrocolloid wound dressing paste adversely affected human skin lipid droplets in vitro, but the implications, including potential cancer links, are unknown.

This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.

This study found that X-irradiation causes hair dysplasia through two mechanisms influenced by oxygen, and cystamine injections after irradiation enhance this effect.

This study found that concentrations of haloperidol and its metabolite in human scalp hair significantly correlated with the daily dose and plasma trough levels in patients taking haloperidol.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study proposed a method to determine residual levels of dichloromethane and chloroform in finasteride using SPME-GC, reporting high linear correlation coefficients for both solvents.

This study found that chemical lumbar sympathectomy with 5% phenol effectively treated idiopathic livedo reticularis in most patients, offering a potential long-lasting solution with repeatable efficacy upon recurrence.

This study introduced a novel microscopy system using an Er3 + −doped femtosecond fiber laser, achieving detailed imaging of biological structures in plant and skin samples with improved spatial resolution for various applications, including in vivo imaging.

This study reports that the newly developed SA-Ca(II) hydrogel has tunable mechanical properties, high biocompatibility, and potential applications in wearable protections and stimuli-responsive electronics.

This study found that HFV70 cryogels, made from Flammulina velutipes extract and hydroxyethyl cellulose, effectively promoted rapid hemostasis and tissue regeneration in full-thickness skin defects in rats, demonstrating improved hemocompatibility, cytocompatibility, antimicrobial, and antioxidant properties.

This study established a reliable method for determining residual solvents in Finasteride using gas chromatography.

This study found that hCG decreased 5α-reductase and androgen receptor levels in skin samples from women in vitro, suggesting that human skin responds to LH/hCG treatment.
