This paper evaluates the therapeutic response of androgenetic alopecia to topical application of specific compounds using digital drug delivery but reports no new clinical results.

This study found that a shampoo containing a 6-active ingredient complex increased β-Catenin production in human hair follicle dermal papilla cells to levels comparable to Finasteride, suggesting potential for promoting hair growth. It also showed good cleaning efficacy, volume, and shine in a sensorial study.

A fatty acid/protein complex in human hair helps protect it from damage.

This study found that platelet factor 4 in platelet-rich plasma suppresses human hair follicle growth and alters related gene expressions, suggesting potential implications for its use in hair loss treatment.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study found that 3-hydroxypropionic acid improved the function of hair follicle cells under oxidative stress, suggesting potential as a treatment for stress-related hair loss.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

In this study, the researchers reported that a newly developed PYGL inhibitor, HTPI, enhanced hair growth in an ex-vivo culture by reducing oxidative damage in hDPCs and inhibiting glycogen degradation in hORSCs, showing potential as a treatment for hair loss comparable to minoxidil.

Hair follicles have unique proteins that vary by species and are influenced by nutrition.

This study found that HMGB1 enhanced hair growth by stimulating PGE2 production in human dermal papilla cells, suggesting a potential therapeutic target for alopecia treatment.

This study developed a method for extracting proteins from micro-sized human head hairs, facilitating proteomic analysis even with limited hair sample availability.

This review discusses the role of the hairless protein (HR) in alopecia and cancer, noting its potential importance in cancer cell growth and survival, and reports no new experimental results.

This study found that HPD is a potent activator of hair follicle regeneration, surpassing the efficacy of conventional minoxidil treatment by modulating Wnt/β-catenin signaling and enhancing follicular proliferation, indicating its potential as a non-invasive hair restoration therapy.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

This study identified two high sulfur protein genes, B2E and B2F, in rats, which are expressed in hair cortical cells during anagen and contribute to hair fiber production.

This study characterized proteins in hair-follicle and hair tissue, identifying similar protein types but with notable quantitative differences, which may reveal aspects of keratin protein synthesis.

This study found that the humanin analogue HNG significantly promoted hair growth in vitro and in vivo by prolonging the anagen phase and inhibiting hair follicle cell apoptosis in mice.

This study found that intermediate filaments and matrix proteins in presumptive hair shaft cells are synthesized sequentially, identifying a new polypeptide component that changes during hair cell differentiation.

In this study, BP201, derived from porcine lung phospholipids, promoted hair growth in mice, especially when combined with minoxidil, and increased hair follicle numbers and dermal papilla cell proliferation.

This study found that the hHa7 gene in hair follicle trichocytes is the first identified to have its expression directly regulated by androgens, suggesting it as a marker for androgen action on hair follicles.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found that valproic acid promoted human hair growth by increasing β-catenin levels, suggesting it may be a potential therapeutic option for alopecia.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

This article discusses a hypothetical model of androgenic hair trichophore composed of various chemical components, but it reports no new empirical findings; the authors emphasize the model's potential impact on hair cosmetics.

This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.
