This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study reports that a 100% herbal hair dye composed primarily of Cymphomandra betacea, Tagetes erecta, and Aloe vera gel provides permanent hair color without causing hair damage, loss, or skin irritation compared to synthetic dyes.

This review discusses existing and emerging treatments for hirsutism, highlighting new home-use laser devices, and reports no new clinical results; the authors note that permanent hair removal remains elusive.

This study reported that gain-of-function mutations in TRPV3 lead to hair loss in mice by disrupting inner root sheath keratinocyte differentiation, ultimately causing follicular keratinocyte stem cell exhaustion and permanent follicle disruption.

A new genetic mutation in mice causes permanent hair loss and skin wrinkling.

This review discusses neutrophil-associated and infiltrative scarring alopecias, as well as promising new treatments, but reports no new clinical results.

This article reviews the basics of hair follicle biology, laser/tissue interactions, and hirsutism and hypertrichosis causes, discussing the long-pulsed alexandrite laser's role in hair reduction without reporting new clinical results.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This article describes the phases of the hair cycle in detail but reports no new clinical findings or results related to alopecia.

This article reviews central centrifugal cicatricial alopecia, focusing on its multifactorial etiology and challenges in clinical diagnosis, and calls for more research and better treatment options.

This study found that the EpiLight Hair Removal System achieved approximately 60% hair removal after 12 weeks following a single treatment, indicating effectiveness and safety for long-term hair reduction.

This review discusses the current therapeutic options for female pattern hair loss and emphasizes the need for managing patient expectations of permanent regrowth, reporting no new clinical results.

This study found that the long-pulse Nd:YAG laser effectively reduces unwanted facial hair across various skin types, with hair regrowth delayed significantly longer than with self-applied methods.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This article reviews the evaluation and management of scarring and nonscarring alopecias, emphasizing the importance of early treatment to prevent permanent hair loss in scarring forms, but reports no new clinical results.

This article discusses surgical hair restoration using micrografting techniques, emphasizing its ability to produce natural-looking results without the "hair plug" appearance, and reports no new clinical findings.

This review discusses the common occurrence of docetaxel-induced hair loss in cancer patients, including permanent cases, and highlights current and experimental strategies like scalp cooling, minoxidil, and new clinical trials for managing and preventing this side effect.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This review discusses various methods of light-based hair removal and reports no new clinical results, highlighting advances in laser and intense pulsed light technologies used for targeting hair pigmentation.

This article reviews primary cicatricial alopecias, focusing on lymphocytic forms such as chronic cutaneous lupus erythematosus, according to a classification by the North American Hair Research Society, and reports no new clinical results.

Laser hair reduction near the eyebrows can cause serious eye injuries even with safety measures.

In this study, a transgenic mouse model was used to demonstrate that targeted cell loss in different tissues led to varying degrees of regenerative outcomes, including reversible impaired glucose tolerance, irreversible hair loss, and permanent moderate deafness.

This article reports a case of pressure alopecia caused by wearing headgear, emphasizing the importance of early diagnosis to prevent potential scarring.

This article reviews treatment approaches for cicatricial alopecia, describing how medication efficacy varies and suggesting autologous hair transplantation for stable cases; no new clinical data are presented.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This review discusses medical and surgical therapies for alopecias in Black women, focusing on the impact of hair-care practices and the importance of patient education, but reports no new clinical results.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

This study finds that the images of soft-haired Kerr black holes show unique rotational, dilational, and drifting effects compared to bald black holes, linked to Noether charges and generalized symmetries.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.
