This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

Oral retinoids can cause side effects ranging from mild to severe, including birth defects, and require careful monitoring and contraception.

This review discusses the types, causes, and treatments for skin pigmentation disorders, examining clinically tested options including 25 plants, four marine species, and 17 medications.

This case report describes an inflammatory skin reaction linked to kava kava ingestion, with the patient's condition resolving after treatment with oral prednisone and topical hydrocortisone.

This article discusses the evaluation and treatment options for alopecia but reports no new clinical results; it highlights the importance of early diagnosis and appropriate treatment.

Finasteride helps improve hair growth in men with hair loss but may increase the risk of erectile dysfunction.

This article reviews pediatric hair growth issues, common causes of hair loss in children, and approaches to diagnosis, but presents no new clinical findings.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This review examines various skin pigmentation disorders, their causes, and potential treatments, detailing 25 plants, 4 marine species, and 17 clinically tested topical and oral medications for managing these conditions.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.

This review discusses epigenetic mechanisms in tissue repair across species and summarizes recent CRISPR-based technologies as promising tools for studying and enhancing tissue regeneration, but reports no new experimental results.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This review discusses the mechanisms, applications, and research evidence of photobiomodulation, highlighting its efficacy, safety, and potential for standardized evaluation methods, but reports no new clinical results.

This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

In this study, subcutaneous recombinant human IL-12 showed a 43% partial response rate in early-stage mycosis fungoides patients refractory to previous treatments, with generally mild to moderate adverse events reported.

The authors concluded that chronic telogen effluvium in middle-aged women presents distinct clinical and histological features that differ from androgenetic alopecia and acute telogen effluvium.

This review covers the use of photobiomodulation devices for hair regrowth in various types of alopecia and reports no new clinical results.

This study suggests that hair follicles may be the primary target in the onset of various skin diseases, potentially spreading to affect the surrounding epidermis.

This review discusses the role of RDH12 in vision, its structural and functional aspects, and related disease mechanisms, but reports no new clinical results; it aims to support therapy development for inherited retinal dystrophies.

Finasteride treats enlarged prostate, shrinks it, improves urination, but may cause sexual dysfunction and isn't for women or children.

This study found that mutations in phosphorylation sites on the PIN3 protein disrupt its phosphorylation and subcellular trafficking, affecting auxin transport and root growth in a cell-type-specific manner.

This study suggests that the action of minoxidil in stimulating hair growth likely occurs at the follicular dermal papilla, though it does not induce new follicle formation.

In this study, a combined regimen of an oral supplement with Pinus pinaster, Grape seed extract, vitamins, and minerals, plus high SPF sunscreen, significantly improved mild-to-moderate facial melasma in 30 women over 84 days, reducing pigmentation and enhancing cosmetic appearance with no reported adverse effects.

In this research, sequencing the chloroplast genomes of 10 Sansevieria trifasciata cultivars allowed the identification of a trnT-psbD deletion marker capable of distinguishing closely related species, and highlighted evolutionary links with Dracaena, contributing molecular tools for taxonomy and phylogenetic studies in Asparagaceae.

Multiple-wavelength radiation helps hair grow by boosting early hair follicle development.

This study highlights the therapeutic benefits of photobiomodulation, which uses light exposure to facilitate tissue repair and prevent inflammation and apoptosis, in treating conditions like arthritis, reumatism, and inflammatory pain, with its complex mechanisms potentially leading to future discoveries and treatments.

This study found that low-level laser therapy increased the expression of proteins in dermal papilla tissues, suggesting it promotes hair growth in male androgenetic alopecia patients.

This study reviews current methods and emerging approaches to prevent and treat chemotherapy-induced hair loss, reporting that evidence-based research is needed to validate effective strategies, which could enhance cancer patients’ quality of life and treatment compliance.
