In this review, the authors highlight a lack of understanding regarding the unique properties of Afro-textured hair, emphasizing the need for scientific collaboration to improve hair care practices and mitigate scalp issues.

In this study, researchers established a mouse model for single follicular unit transplantation and reported successful integration and piloerection of transplanted hair follicles with surrounding host tissues.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This study found that supplementing pregnant cashmere goats' diets according to nutritional standards improved their fiber production, growth, fertility, and the development of kids' secondary hair follicles.

In this study, bromocriptine's inhibition of prolactin promoted secondary follicle development during anagen in cashmere goats, likely via changes in specific gene expressions, despite not affecting fiber characteristics or primary follicle activity.

In this study, melatonin exposure promoted hair follicle fiber growth in Cashmere goats, suggesting that it may mediate hair follicle development through long non-coding RNAs affecting vascular and extracellular pathways.

This study explored proteomics to investigate protein changes during protein synthesis and keratinization in maturing wool fiber, but the relationship to fibre development remains largely unknown.

This study found that Tibetan cashmere goats have genetic adaptations that contribute to their finer cashmere, possibly enhancing their ability to withstand the cold climate of the Tibetan plateau, while identifying specific genes related to hair growth, pigmentation, and heart development.

In this study, researchers used the CRISPR/Cas9 system to edit the FGF5 gene in Dorper sheep, observing increased density and finer wool, along with changes in cortisol levels and antioxidant enzyme activity linked to hair follicle development.

This study reports the development of a prototype robotic hair transplant system capable of efficiently harvesting and implanting hair grafts, showing promising accuracy and performance in tests using a spherical scalp phantom.

This study found that the finer fibers of Alpas cashmere, compared to ordinary cashmere, are associated with the down-regulation of specific keratins and keratin-associated proteins, suggesting a molecular target for breeding cashmere goats with improved fiber quality.

This review discusses recent advances in the development of electrospun pectin nanofibers for biomedical applications, highlighting strategies to improve their mechanical properties and biological functions and addressing challenges like material variability and regulatory issues.

This study found that cashmere has a significantly smaller mean fiber diameter compared to sheep and goat wool, and identified key proteins that may influence this difference.

This study reported that exposure to melatonin promoted hair follicle fiber growth in an in vitro Cashmere goat model, potentially by influencing pathways related to the extracellular matrix and microvascular system.

This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

In this study, researchers successfully constructed a high-precision three-dimensional model of human skin dermis, revealing a detailed analysis of dermal porosity and pore diameter distribution, which can aid the development of biomimetic tissue-engineered skin.

This study found that PSAT1 is a key regulator of cellular survival and regenerative capacity in cashmere goat hair follicle stem cells, highlighting its role in the SHF cycle and its potential as a target to boost cashmere fiber production.

This study found that knocking out the transactivation domain of Miz1 in mouse keratinocytes disrupted hair follicle orientation, caused irregular pigmentation, and increased keratinocyte proliferation, indicating Miz1's role in hair follicle development and morphogenesis.

This study examined the Spanish Merino breed's wool quality, identifying 74 genetic variants linked to key wool traits like fiber diameter and staple length, which could help restore the breed's potential for producing high-quality wool.

In this study, researchers found that knocking down the transcription factor Csdc2 inhibited the proliferation of dermal papilla cells in cashmere goats, and identified its regulatory relationship with the gene Robo2, providing insights into the genetic mechanisms influencing cashmere fiber growth.

This study by Bansaccal et al. found that skin with higher levels of type I collagen density and elasticity in the dermis can inhibit basal cell carcinoma development and spread by acting as a natural barrier against cell reprogramming in mice.

This study investigated how different 3D bioprinted scaffold structures affect immune responses and hair growth in mice, finding that moderate immune response induced by certain structures stimulates hair growth, while excessive immune response can hinder hair follicle development.

This study created new methods to test how well hair care products clean and protect hair from pollution, finding a wide range of effectiveness among different formulas in removing pollutants and preventing their deposit on hair fibers.
