This report describes three cases of erythromelanosis follicularis faciei et colli showing significant improvement in facial telangiectasia following treatment with a 595-nm pulsed dye laser, with minimal recurrence observed during follow-up.

This study evaluated various herbal combinations for hair coloring and found that a formulation of Henna and Indigo provided a natural reddish-brown color with better retention compared to marketed herbal hair dyes, without using synthetic agents that can cause allergic reactions.

In this study, researchers explored the use of natural herbal hair dyes made from tannin-producing plants like henna and pomegranate, reporting that these dyes can permanently color hair without causing damage or irritation, unlike synthetic dyes.

595 nm pulsed dye laser is a cost-effective treatment for nonmelanoma skin cancer with a low recurrence rate.

This study concluded that replacing the synthetic dye Sunset Yellow with curcumin as a colorant in foods may avoid cytotoxic and genotoxic effects observed in mice.

In this mouse study, researchers found that hydrogen peroxide and monoethanolamine in hair dyes may be key contributors to dermatitis and hair loss due to oxidative stress.

This study found various ABC transporters are transcribed in human hair follicles, suggesting their possible role in HF biology and potential for new therapeutic interventions.

This study found that using a high-viscosity, high-amine-content silicone fluid as a pretreatment can protect hair from bleaching and dyeing damage without affecting these processes.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

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

This study examined how different hair dye processes affect hair structure at a molecular level, finding that oxidative dyes increase keratin porosity more than non-oxidative dyes, and highlighted emerging technology aimed at reducing hair damage while preserving color quality.

In this study, a new delipidisation method that removes over 97% of key lipids from wool rapidly and without yellowing was reported to improve wool processing and printing quality.

This article discusses the characteristics and challenges of treating ulerythema ophryogenes, noting the limited effectiveness of emollients, vitamin A, retinoids, and transient response to corticosteroids, with some success using dye laser therapy.

This article reviews factors influencing hair aging and available treatments like minoxidil and finasteride for androgenetic alopecia but reports no new clinical results.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This study found that bleach treatments significantly increased hair surface roughness and decreased Young's modulus, indicating marked changes in hair's molecular structure which may affect future hair-care product formulation.

This paper suggests that coating hair with drug-loaded nanotubes may offer durable drug delivery and color applications, with potential for both human and veterinary uses.

This study found that 9% of tested patients had positive patch test reactions linked to hair care products, with most reactions clinically relevant and commonly involving allergens like p-phenylenediamine.

This mini-review summarizes the Trichoscan as a sensitive tool for measuring hair growth parameters, demonstrating its effectiveness in detecting treatment response in androgenetic alopecia but noting some practical limitations.

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

This study reports that the completeness of DNA degradation in hair during cornification varies among individuals and affects the success rates of forensic hair DNA analysis.

This study observed significant differences in hair care practices and biologic hair parameters between Caucasian and African American women, which may contribute to varying hair fragility and growth.

This review discusses the role of hair dyes in cosmetic dermatology, their effects on hair and scalp health, and the importance of dermatologists understanding potential side effects; it reports no new findings.

This review discusses various skin conditions linked with chronic kidney disease and highlights effective treatments but does not provide new clinical results.

This study found that bleaching, dyeing, and UVA/Vis radiation caused significant cuticle damage and protein loss in both Caucasian and Afro-ethnic hair, highlighting the aggressive nature of these treatments.

Hydrogen peroxide in hair dye can cause hair loss.

This review explores the factors contributing to premature graying of hair, highlighting the role of genetic and environmental influences such as oxidative stress, and discusses potential interventions like diet and herbal remedies, while noting the limitations of common treatments like hair dyes.

This narrative review discusses adverse reactions associated with hair care products, specifically irritation dermatitis and allergic contact eczema, and suggests the need for attention to common allergens like PPD, GMTG, and ammonium persulphate.

This study found that procyanidin oligomers bind to keratin and inhibit oxidative hair damage, suggesting their potential use in protective hair care products.
