Imatinib can repigment grey hair, while SU11428 can cause temporary hair depigmentation.

This narrative review discusses the evolution and diverse medical applications of laser technologies, particularly in dermatology and skin biology, without reporting new research findings.

In this research, SEU-302, a newly developed covalent organic framework, exhibited significant antibacterial and wound-healing properties in vitro and in vivo, effectively eliminating Staphylococcus aureus and reducing inflammation under light activation, thereby showcasing its potential for therapeutic photodynamic applications.

This study found that mackerel fermented fish oil protected human keratinocyte cells from UVB-induced oxidative stress by scavenging free radicals and reducing cellular damage.

This study established an animal model using UV-irradiated C57BL/6 mice to assess hair luster, reporting that UV exposure alters keratin-associated protein gene expression, and suggested potential for developing effective hair care products by evaluating treatments like oral minoxidil.

The letters discussed medical tools, costs, treatment efficacy, and patient care complexities.

This article reviews the use of light-based technologies for hair removal, detailing different laser systems and treatment protocols, but reports no new clinical results.

Riboflavin with blue light speeds up hair dyeing, making it faster, safer, and long-lasting with less hair damage.

This review examines the FDA's 510(k) approval process for low-level laser therapy devices used in treating androgenetic alopecia and reports no new clinical findings.

This chapter reviews four innovative devices for follicular unit excision in hair restoration surgery, but it does not report new clinical results or outcomes.

This study found that repeated treatments with the long-pulsed ruby laser result in a small but statistically significant reduction in unwanted hair, with high patient satisfaction despite modest efficacy.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

In this study, K19-lacZ transgenic mice exhibited epithelial-specific reporter gene expression in tissues such as the pancreas and stomach, suggesting the K19 promoter is a valuable tool for studying epithelial cell biology.

This study found that genipin-based pigments, accelerated by riboflavin and blue-light photocatalysis, achieved commercial-level hair dye results with enhanced gloss and excellent color retention while reducing cuticle disruption, offering a potentially safer and faster alternative to traditional hair coloration methods.

In this study, the researchers found that measuring tacrolimus levels in scalp hair could be a reliable method for monitoring drug exposure in kidney transplant recipients, offering an alternative to frequent blood tests by utilizing self-collected hair samples.

This study using an apertureless scanning near-field optical microscope found that dye restricted to hair's periphery remains mainly on the surface and in the endocuticle.

In this study, diode laser treatment for hair removal effectively reduced hair across different ethnicities and Fitzpatrick skin types, though side effects like sensitivity, hyperpigmentation, and burns varied by ethnicity and number of treatments. However, these were temporary and did not compromise overall treatment success.

In this study, cisplatin was found to induce cell death in human hair follicle cells through hydroxyl radical generation and Bcl-2 down-regulation, suggesting potential strategies for preventing chemotherapy-induced alopecia.

This paper describes a new technique using gentian violet to improve visualization during follicular unit extraction in white-haired patients, suggesting it enhances the accuracy of the procedure.

This study suggested that electron spin resonance techniques can potentially measure gamma ray exposure in human hair samples, though variability and time sensitivity pose challenges for accurate dose estimation.

This case study of a patient with dissecting cellulitis of the scalp found that multiple medications, including isotretinoin, achieved only modest improvement, and symptoms returned after treatments were stopped.

This study reports that a robotic and AI-based system successfully analyzes FUE hair transplant procedures, aiding surgeons in planning and assessing operation success through detailed pre-op and post-op evaluations.

This study found that low-level laser therapy accelerates skin regeneration in gamma-irradiated mice and enhances the biostimulatory effect on hair follicles.

This study describes a new method using near infrared femtosecond laser pulses to precisely ablate individual cells in the Drosophila epidermis and peripheral nervous system without damaging surrounding tissues, allowing for detailed observation of cellular responses post-ablation.

This review discusses laser-assisted drug delivery for enhancing topical treatment efficacy in various dermatological and medical applications but reports no new clinical results, emphasizing the need for further research to optimize its use.

This study found that using low-power lasers on cryosurgery-induced wounds in rats can prevent hair follicle necrosis and increase hair follicle numbers, with the experimental group showing significantly more hair follicles than the control group across all time points studied.

This study suggests that selective photothermolysis of sebaceous glands using free electron laser pulses may offer a novel approach to treating acne by causing targeted thermal damage without affecting the epidermis.

This study found that multiphoton microscopy effectively visualizes the microstructure of in vivo mouse skin, offering a clear view of various skin layers and components like corneocytes and collagen fibers.
