This review discusses the distribution, habitat, and medicinal uses of the witch hazel species in the Hamamelidaceae family, reporting no new experimental results.

This study developed and validated a method to analyze active ingredients like nicotinamide and tocopherol in hair nourisher products using HPLC, which may facilitate quicker market access for these products.

In this study, melatonin-loaded Pickering emulsions stabilized by chitosan-dextran sulphate nanoparticles and enhanced with lecithin showed improved photostability, antioxidant activity, and follicular delivery in androgenic alopecia-affected rats, potentially rivaling commercial minoxidil for hair loss treatment.

This study found that mimicking the XPD point mutation in mice resulted in trichothiodystrophy-like symptoms, supporting the role of basal transcription and DNA repair defects in the disease.

This study found that mice lacking the vitamin D receptor (VDR) developed skin tumors more rapidly than those with normal VDR activity, regardless of 1,25-dihydroxyvitamin D(3) presence.

This review presents clinical and preclinical evidence supporting innovative regenerative approaches to treat vitiligo, as existing treatments lack a specific cure and predictable long-term repigmentation outcomes.

This study suggests that topically applied fusidic acid may penetrate only the most superficial layers of canine skin but can reach sufficient concentrations to potentially treat infections caused by pathogenic staphylococci.

Combining UV therapy with PRP heals chronic wounds faster and reduces pain.

This study's literature synthesis suggests that silymarin, derived from milk thistle, may offer protective benefits for the skin, including defense against UV damage and support for wound healing, though further clinical studies are needed.

In this study, researchers found that while sunscreens added to hair products do not provide expected protection, the dark hair absorbs the most radiation across all wavelengths, indicating a need for enhanced protection.

This review explores the application of nanotechnology in cosmetics, highlighting its role in enhancing skin penetration, sustaining drug action, and protecting against UV radiation, while also addressing regulatory considerations and potential exposure routes.

This study developed and validated a reliable RP-HPLC method for accurately quantifying dutasteride in pharmaceutical formulations and bulk pharmaceuticals using a Shiseido C18 analytical column, demonstrating precision, accuracy, and sensitivity across a concentration range of 10 to 22 ppm.

In this study, researchers found that contrary to expectations, keratin 10 domains did not reduce cell proliferation and instead increased tumor development in genetically modified mice.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This study found that iron deficiency anemia is a key factor in the development of telogen effluvium, and higher 25-hydroxyvitamin D3 levels in TE patients may be linked to increased UV exposure.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study demonstrated that visible light lightens blond hair more effectively than ultraviolet light, attacking melanin granules directly, whereas ultraviolet light primarily damages other hair tissues following washing.

This study developed three spectrophotometric methods to effectively measure finasteride in bulk and tablet forms, providing accurate results that align closely with labeled claims.

This review discusses the antioxidant and photoprotective potential of Polypodium leucotomos for use as a natural sunscreen ingredient and reports no new experimental results; further studies are recommended to evaluate its effectiveness.

This study suggests that keratin films, which model hair damage sensitivity, remained intact after shampoo and conditioner treatments and showed potential for evaluating hair texture and adsorption.

This study reported that discarded squid ink was used to develop a high-performance, environmentally friendly hair dye that offers a stable deep black color, UV protection, and preserves hair structure, while showing excellent biosafety in lab tests.

This study validated an HPLC analytical method for evaluating fenasteride in commercial products, finding it to be sensitive, selective, and within acceptance criteria for specificity, precision, and stability, making it suitable for quality control testing.

In this animal study, hibiscus leaf simplicia ointment was found to protect red blood cell levels and promote better hair growth in UV-exposed rats, though it did not maintain normal skin histology; the ointment showed no significant acute dermal toxicity.

In this study, PDO, PLLA, and PCL thread implants in ageing rat skin did not alter MMP1 gene expression but maintained collagen levels similar to young skin without UV-B exposure, suggesting possible benefits for skin collagen but not gene expression modification.

This study identified seven genes that may serve as biomarkers for diagnosing skin cutaneous melanoma by analyzing the relationship between UV exposure, ferroptosis, and the cancer's pathology.

This study reports that hair oil formulations using Arnica montana in castor and mustard oil bases showed effective results in quality and quantitative analysis through UV visible spectrophotometer, FTIR, and HPTLC testing methods.

In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.

This review examines how mesenchymal stem cells and their derivatives may enhance skin regeneration and rejuvenation, but it reports no new clinical results; the authors suggest iPSC-derived MSCs hold promise for future therapies.

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 review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.
