This study analyzed clinical and histological reports and concluded that blue light therapy is safe for human skin, with potential photoprotective effects against UV irradiation due to its impact on skin pigmentation mediated by Opsin-3.

In this mouse study, UVA and UVB exposure led to hair follicle miniaturization, graying, and prolonged hair cycle duration, associated with changes in stem cells and increased Wnt signaling activity.

This study revealed that photobiomodulation significantly improved hair density in androgenetic alopecia patients, with laser treatments being more effective than combined laser/LED treatments, while device style did not significantly affect outcomes.

This abstract provides no new clinical results; it discusses the role of surgery and interventional radiotherapy in treating cutaneous squamous cell carcinoma.

This review discusses the potential benefits of phytochemicals for hair care and emphasizes the need for more robust preclinical and clinical studies, without reporting new clinical results.

In this study, reduced hair density, diameter, and follicle miniaturization were key characteristics of female pattern hair loss in Southern Chinese women, with occipital and temporal sites also affected.

This study reports that A132, a hair dye ingredient, induces phototoxicity and photogenotoxicity via mitochondrial apoptosis when exposed to sunlight, suggesting potential risks of oxidative stress and hair damage.

This report documented a successful and sustained hair restoration surgery using follicular unit transplantation for temporal triangular alopecia, lasting over six years.

This study reports two distinct patterns of hair changes in postmenopausal women, linking diffuse generalized scalp hair loss to older age and frontal hair loss to higher facial hair scores and younger age.

This study found that Sithong-bao seed coat extract, with high phenolic content, exhibited the strongest antioxidant properties among certain Thai tamarind cultivars, suggesting potential for nutraceutical development.

Light therapy can effectively treat vitiligo and hair loss caused by a specific medication.

This study found that a hydroponic buffer solution induced the formation of abundant long root hairs, termed "hedgehog roots," in several plant species but not in onions.

This study found that photochemical and cosmetic chemical oxidation of hair causes surface damage by delipidation and acid formation, which can be characterized and quantified using microfluorometry and X-ray photoelectron spectroscopy.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study found that four out of ten patients with alopecia areata experienced some hair regrowth after PUVA therapy, though this treatment should be reserved for those unresponsive to other options due to potential long-term side effects.

This study describes a method to extract and characterize keratin particles from human hair, finding they can encapsulate the anticancer drug Paclitaxel with significant efficiency, releasing it in a pH-dependent manner potentially beneficial for targeted cancer treatment.

This study found that a blackcurrant extract with phytoestrogen activity increased hair number and stem cell marker expression in a menopausal rat model, suggesting a potential benefit for hair loss.

This study validated a highly selective and fast LC–MS/MS method for accurately measuring levels of tadalafil and finasteride in human plasma, adhering to international bioanalytical guidelines.

This review highlights that pharmacotherapy for polycystic ovary syndrome should address individual patient concerns, with metformin beneficial for reducing weight and metabolic risk, and lifestyle modifications also important.

This study reports that keratinocytes grown under low oxygen conditions (physioxia) demonstrated reduced reactive oxygen species production and increased antioxidant enzyme activity compared to those in higher oxygen conditions, highlighting the role of oxygen in regulating skin antioxidant defenses.

This study found that LC-MS/MS assays provided more reliable and precise steroid measurements in human serum compared to traditional immunoassays, particularly at lower concentrations.

This review explores marine algae-derived phenolic compounds and their potential cosmeceutical benefits, but reports no new clinical results.

This study found that shallot extract may promote hair growth in androgenetic alopecia by reducing inflammation and modulating gene expression related to key hair growth pathways.

This study found that PCOS is common among Iranian women, with phenotypes involving hyperandrogenism exhibiting worse lipid profiles and higher rates of metabolic syndrome compared to healthy women.

In this study, researchers found that human adipose tissue-derived mesenchymal stromal cells exhibit significant phagocytic ability against various particles and pathogens, which might enhance strategies for addressing specific local and systemic infections due to their regenerative properties.

This review summarizes research finding over 150 new molecules with various biological activities from traditional herbal medicines studied in China, Mongolia, Uzbekistan, and Bangladesh.

In this study, sublingual tofacitinib achieved a longer estimated half-life than oral administration in treatment-resistant alopecia areata patients, potentially supporting daily dosing; overall treatment response was modest.

This review found that oral and topical phosphodiesterase inhibitors and topical prostaglandin analogues are safe and effective treatments for various skin diseases, including psoriasis, atopic dermatitis, vitiligo, and alopecia.

This study demonstrated a method for delivering a photosensitizer, Ammi majus fructuum furocumarines, into hair follicles using calcium carbonate particles, followed by UVA irradiation, which led to significant pigment accumulation, indicating potential improvements for photochemical therapy.

In this study, researchers suggest that laser-assisted drug delivery could enhance the administration of platelet-rich plasma, and potentially bimatoprost or minoxidil, for patients with androgenetic alopecia by ensuring uniform placement in the dermis without injection pain.
