This study reported that using autologous micro-grafts according to the Rigenera® protocol may improve hair restoration and increase hair follicle numbers in patients with androgenetic alopecia after 6 to 9 months.

This study observed that key signaling events controlling hair growth in ferret follicles occur between 0 and 4 days after melatonin implantation, highlighting distinct processes in follicular regeneration and fibre growth.

This study found that BMP2 and BMPR-IA inhibited, while Noggin promoted, hair follicle growth in yaks by affecting skin epithelial cell activity.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

This study found that enhanced expression of the Sonic hedgehog gene via an adenovirus vector accelerated hair regrowth in mice with chemotherapy-induced alopecia.

This review discusses the histologic features of nonscarring alopecia and highlights the importance of clinical-pathological correlation for accurate diagnosis, but reports no new clinical results.

This study demonstrated that keratin extract can stimulate hair growth by inducing the anagen phase in telogenic mice.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

Cosmeceuticals may benefit skin health but need more research for efficacy and safety confirmation.

In this study, miR-31 was found to play a significant role in hair cycle regulation in mice by controlling key gene expressions involved in hair growth and differentiation.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This study explored the complex developmental processes of human hair, emphasizing the intricate interactions required for hair follicle morphogenesis and its implications for drug incorporation and concentration interpretation, particularly in early childhood.

This research found that spontaneous and depilation-induced hair growth result in biologically distinct telogen phases in murine skin, with variations in thickness, pigment content, and hair follicle composition.

This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

This review summarizes the anatomical and physiological aspects of human hair and its clinical significance, but does not report new research findings.

This study suggests that apigenin may stimulate hair growth by downregulating TGF-ß1 gene expression in human epidermal keratinocytes and promoting hair follicle elongation in a rat hair follicle culture.

This review discusses various biologics for hair aging but reports no agent capable of reversing the natural aging process of hair.

This article discusses strategies for changing hair color by regulating target genes in hair follicles using advanced delivery systems, but it reports no new experimental findings.

This study found that topical application of a Biofield Energy Healing-treated mixture of herbal extracts in mice increased hair growth and melanogenesis compared to untreated extracts.

This study found that dermis micrografting improved hair growth and density in patients with androgenetic alopecia over 4, 6, and 12 months, suggesting it could be a novel treatment option.

The document reviews various hair and nail disorders, their causes, and treatments, emphasizing the need for proper diagnosis and the link between nail changes and systemic diseases.

The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.

In this study, oral zinc sulphate was found to cause hair hypopigmentation and significantly inhibit eumelanogenesis in mice.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.
