This article provides a diagnostic guide for clinicians to differentiate between various hair shaft disorders by using a structured question-by-question approach but does not report new clinical findings.

In this study, researchers used embryonic chicken skin as a model to show that perturbing calcium signaling can induce feather bud formation in areas that typically do not form them, highlighting developmental bioelectricity as a crucial yet underexplored layer in tissue patterning.

This study analyzed 853 articles to reveal that research on silica-based nanobiomaterials in regenerative medicine has rapidly increased, with distinct regional differences in impact and emerging focus areas in drug delivery and wound healing.

This review discusses the integration of nanoparticles with microneedles to improve drug delivery through enhanced stability, bioavailability, and controlled release, noting ongoing challenges with stability, scalability, and safety.

In this study, researchers explained that healing of extensive skin defects involves granulation filling the wound cavity, followed by epithelialization from skin edges and hair follicles, which are crucial steps in wound healing.

In this study, zinc oxide nanoparticles were synthesized using a sustainable method from the Lepidium sativum L. plant, and incorporating these nanoparticles into Sunblock Lotion significantly increased its sun protection factor.

In this study, researchers found that chemical treatments like bleaching can cause severe damage to the hair cuticle, with previously modified hair showing complete deterioration compared to the partial degradation seen in virgin hair, highlighting the need for mindful cosmetic practices.

This review discusses the health risks of mercury from dental amalgam, including higher levels of mercury in dentists and pregnant women, and suggests using composite resins instead.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

This source discusses the potential of integrating herbal extracts with nanotechnology in skincare products, highlighting improved effectiveness and targeted delivery of active ingredients to skin cells compared to traditional formulations.

In this study, researchers analyzed a herbal shampoo containing Momordica charantia extract and Hibiscus Rosa-Sinensis, noting it could support collagen development and hair growth. The shampoo, tailored to various hair and scalp conditions, was confirmed free of certain harmful heavy metals.
