This study found that oxidative stress in hair follicle melanocytes contributes to premature aging and apoptosis, providing insights into graying as a model for studying aging and testing antiaging therapies.

Dr. Shyam B Verma encourages more scientific research on hair disorders and criticizes the unscientific hair care market in India.

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 article recommends creating a system to educate users about the ingredients and side effects of hair coloring products and does not report new research findings.

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 paper reviews recent research on hair graying, suggesting that an imbalance in oxidative stress handling may affect melanocyte stem cells and melanin production with age, and calls for exploring strategies to prolong melanin production.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

This article reviews innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.

This study found that hair analysis is an effective non-invasive method for assessing metabolic fluctuations, showing stable advanced glycation end products levels that correlate with age and differ significantly between diabetic and non-diabetic rats.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This review discusses the harmful effects of coloring shampoos containing trihydroxybenzene on the scalp-skin barrier and emphasizes the need for safer ingredient selection to prevent side effects.

In this study, researchers formulated a polyherbal hair oil using ingredients like coconut and castor oils, and reported that it boosts hair growth, reduces hair fall and dandruff, and adds shine, with minimal adverse effects compared to market formulations.

This review discusses factors influencing hair pigmentation and the etiology of canities, noting the lack of clarity in underlying mechanisms and calling for further research on treatment options.

This study identified that copper depletion in dermal papilla cells reduced hair growth by boosting ROS levels, but ROS scavengers like NAC and ascorbic acid partially alleviated this effect.

This study found that compromised antioxidant activity in gray hair follicles affects both mature melanocytes and their immature precursors, linked to down-regulation of melanogenesis-related genes.

This review examines the potential and challenges of extracellular vesicles in cosmetics, noting their transformative impact despite regulatory and production hurdles; it reports no new experimental results.

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

This review highlights silk fibroin and its nanocomposites as promising materials for wound healing, addressing challenges in chronic wound treatment, especially in developing countries, and examines the obstacles in bringing silk-based products to market.

This paper conducts a scientific evaluation of fine hair issues in American bovine hides and suggests measures to minimize this seasonal problem, particularly in winter production.

This review discusses the use and sustainability challenges of luxury animal hair fibers in the fashion industry and reports no new research findings.

This study found that exosome-based therapy using rose stem cell-derived exosomes may safely induce hair repigmentation in individuals with gray hair, particularly for those with shorter durations of graying and androgenetic alopecia.

In this study with organ-cultured human scalp hair follicles, high mTORC1 activity correlated with gray/white hair and reduced pigmentation, while inhibiting mTORC1 with rapamycin increased hair growth and pigmentation, suggesting mTORC1 inhibition could be a strategy for treating hair depigmentation and loss.

This review discusses age-related and environmental factors affecting scalp hair changes in women, highlighting diagnostic complexities and ongoing research into targeted treatments, without reporting new clinical results.

This article reviews the historical development of pharmacology up to the mid-20th century and outlines its transition from a support role in therapeutics to a distinct scientific discipline, but reports no new findings.

This review discusses the biology of hair follicles and common hair disorders in the elderly but reports no new clinical results.

This review discusses the potential risks of formaldehyde in hair keratin treatments like Brazilian blow-dry, and reports no new clinical results; it emphasizes the need for greater safety assessments including occupational exposure.

This review discusses various strategies to enhance drug delivery through the skin barrier, highlighting liposomes as promising carriers for increased dermal concentrations in topical therapies, but reports no new research results.

Hair transplantation in East Asians needs special techniques to ensure natural results and prevent complications due to their unique hair and scalp characteristics.

In this study, researchers examined chicken feather follicle tissues from differently colored chickens and found that the genes SLC45A2 and GPNMB are involved in promoting melanin deposition, which enriches understanding of the genetic mechanisms affecting feather color.
