This article reviews various reconstructive surgery techniques for scalp wounds and emphasizes factors affecting aesthetic outcomes, but it presents no new clinical findings.

This study observed that glycine inhibited root growth and stimulated root hair development in habanero pepper seedlings, with ethylene signaling suggested to mediate these effects.

This study found that manipulating SIMK expression in alfalfa affects root hair growth, infection thread and nodule formation, and overall plant biomass, highlighting its potential biotechnological applications.

This study found that overexpression of R-spondin 3 in a mice model impaired hair morphogenesis and regeneration by reducing hair matrix progenitor cell proliferation, thus disrupting the Wnt pathway's regulation of stem cells.

In this study, the PLP2 gene was found to promote secondary hair follicle development in Liaoning cashmere goats, with its expression negatively regulated by melatonin and potentially affecting follicle development via the BMP pathway.

Among families with pediatric brain disease, this study identified over 200 novel genetic causes, revealing potential treatment points using drug repurposing or nutritional supplementation.

This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.

This study provides a comprehensive analysis of anabolic-androgenic steroids, reporting that their use enhances muscle mass but is associated with significant health issues including cardiac muscle hypertrophy, liver disease, and changes in gender characteristics, emphasizing the need for patient awareness of these risks.

This review explores how hair dyes and perms can damage hair structure and notes that while some adverse outcomes like skin irritation and allergic reactions have been reported, evidence from human studies remains inconsistent regarding potential risks, including cancer.

This review covers hair dye formulations, their mechanisms, and potential applications, but reports no new findings; the authors highlight the process of oxidative dyeing and repairing damaged hair.

This review covers cell transplantation methods for genitourinary reconstruction, discussing tissue sources and complications but presenting no new clinical findings.

This review highlights morphological factors contributing to age-related alopecia and suggests further research to understand and potentially mitigate cellular aging processes affecting hair quality.

This review investigates molecular mechanisms behind PCOS pathogenesis and discusses potential therapies, but reports no new clinical results.

This genetic study identified a potential interval for the Marie Unna hypotrichosis gene but found no mutations in the nearby hr gene, suggesting its involvement remains unconfirmed.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

This review discusses the etiology, diagnosis, and management of polycystic ovary syndrome and reports no new clinical findings.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This review discusses the prognosis and treatment options for hair shaft disorders, finding no studies but suggesting some disorders improve with specific treatments like minoxidil and retinoids, while gentle hair care remains essential.

Fear of hair-related issues causes significant mental distress, especially in high-stress women.
