Disulfide bonds are crucial for hair structure during keratinization.

In this study, the researchers used the dual-flow-RootChip to show that Arabidopsis roots can locally adapt their hair development in response to asymmetric phosphate conditions.

This review examines the potential of swellable microneedles in drug delivery and diagnostics, highlighting innovations and challenges in their use for chronic disease treatment, but noting that issues like physiological responsiveness and long-term stability still require research.

This study reports that a novel UV-based crosslinking process for collagen sponges significantly decreases crosslinking time compared to traditional methods, and supports effective cell proliferation and wound regeneration in a mouse model, without causing abnormal angiogenic or immune responses.

This study found that newly developed nanogels for transdermal delivery of finasteride were stable, showed excellent drug permeation through the skin, and ensured biocompatibility without causing irritation or toxicity.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This review explores biomaterials in non-viral gene delivery systems and highlights the need for more research to better understand how various parameters affect gene delivery processes, without reporting new experimental results.

This study presents a novel hydrogel scaffold made from tilapia collagen, which when activated by ultrasound, reprograms macrophages to promote wound healing, enhance angiogenesis, and stimulate hair follicle regeneration, offering a potential new method for treating inflammatory wounds.

Repetin is a protein involved in skin and hair development, binding calcium and compensating for other proteins when needed.

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 combining the natural product cedrol with minoxidil can improve the treatment of androgenetic alopecia by reducing the minoxidil dose needed, while a new nanocarrier system enhances drug delivery and effectiveness at hair follicles.

This study introduced and validated new spectrophotometric methods to simultaneously determine finasteride and tadalafil in Entadfi™ capsules with high sensitivity and without interference from excipients.

In this study, PEG and keratin scaffolds selectively influenced protein release rates based on charge and size, suggesting their potential for targeted delivery of protein therapeutics.

In an animal model, this study found that PEG hydrogels delivering M2 macrophage-derived exosomes effectively promoted M1 to M2 macrophage transition and enhanced wound healing.

This review discusses the relationship between skin microbiome changes and conditions such as ageing and skin disease, emphasizing the need for further research, but reports no new findings.

This study investigated how 2D and 3D cell culturing methods influence hair follicle morphogenesis, finding that 3D cultures responded more expectedly to minoxidil while 2D cultures reacted better to DHT treatment, challenging the assumption that 3D cultures are always superior.

This study provides a comprehensive review of the use of electrospinning technology to create 3D porous structures for bone implants, emphasizing the synergy between biomedicine and materials science necessary for developing orthopedic materials.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

In this study, researchers developed a polyphenol–amino acid nanozyme capable of controlled hydrogen peroxide delivery, which effectively activated hair follicles via oxidative stress in a mouse model, suggesting a potential non-pharmacological treatment for alopecia.

This narrative review discusses the role of injectable biomaterials in dental tissue regeneration, highlighting their suitability for treating small, hard-to-access oral defects compared to pre-formed scaffolds, and explores the potential use of nanofibers in dental applications.

This study found that CD44 and CD49d together enhance signaling pathways in lymphocytes in mice with alopecia areata, influencing their activation and function.

The hydrogel is safe, reduces oxidation, and helps heal wounds effectively.

This article illustrates that dermoscopy can quickly diagnose hair breakage due to intrinsic and chemical factors in patients of African descent, although published findings are limited.

This review discusses the role of keratin-associated proteins in the growth and characteristics of wool and hair fibres from sheep and goats, and highlights areas for future research, but it presents no new findings.

This study found that using composite alginate hydrogels containing Aloe vera, CMC, and tragacanth can improve the encapsulation efficiency and protect pumpkin seed protein hydrolysates from degradation during simulated gastrointestinal digestion, potentially increasing their applicability as functional food components.

In this study, researchers found that a composition containing mannose-6-phosphate significantly reduced the total skin pore area by 24% in women after 56 days and by 30.2% in men after 7 days, suggesting its effectiveness in improving pore appearance by targeting dermal and epidermal modifications.

This study reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

This study found that epidermolysis bullosa simplex keratinocytes had impaired mitochondrial activity and more dispersed mitochondrial distribution compared to normal human keratinocytes.

This study found that trichohyalin is expressed in cancerous tongue epithelial cells, while plectin-1 expression may indicate malignancy.
