This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.

This study found that the lack of expression and deletion of specific hair keratin genes on chromosome 7q36 in Hirosaki hairless rats suggests the crucial role of these genes in hair growth.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This study identified a novel locus for hereditary hypotrichosis simplex on chromosome 13q12.12~12.3 in a four-generation Chinese family.

This study revealed that Patched receptors establish a Hedgehog signaling gradient in developing hair follicles, which may influence their formation and potentially offer a diagnostic tool for distinguishing Hedgehog-driven tumors.

This review explores the hormonal factors related to hidradenitis suppurativa, emphasizing insulin resistance and pro-inflammatory adipokines, but reports no new clinical findings and suggests further research is needed.

This article discusses the introduction and market presence of the Italian hair product Kevis but presents no new clinical findings.

This study found that α-ketoglutarate protected dermal papilla cells from oxidative stress by enhancing the Nrf2 pathway and mitigating cell damage through the ERK/Nrf2 axis.

In this study, researchers found that NKB placental mRNA expression was higher in women with PCOS, particularly in pregnancies with female offspring, and that NKB expression varied with fetal gender, suggesting a role in PCOS-related placental dysfunction.

This study found that the E6 gene, but not E7, was responsible for HPV8-induced expansion of keratinocyte stem cells in hair follicle junctional zones in mice.

In this study of women with hirsutism or androgenic alopecia, diverse underlying endocrine disorders including polycystic ovaries and various enzyme deficiencies were detected, often associated with elevated testosterone levels.

In this study, researchers found that recombinant human HAPLN1 promoted hair growth in mice and human hair matrix cells by activating specific signaling pathways, suggesting it may offer a potential hair loss treatment with fewer side effects than existing medications.

Human hair keratin can help repair fat tissue.

This study found that heparanase is primarily located in the inner root sheath of human hair follicles during the anagen phase, and inhibiting it in cultured hair follicles induces a catagen-like process.

This study reports that a widespread founder SERPINB7 mutation underlies Nagashima-type palmoplantar keratosis, which is a common form of palmoplantar keratosis in Asian populations.

This study found that the loss of a functional hr gene in mice leads to premature and abnormal hair follicle regression, disrupting normal hair cycling and architecture.

This chapter reviews procedural hair restoration techniques, including platelet-rich plasma and hair transplantation, and reports no new clinical findings.

This study found that Hairless (Hr) acts as a corepressor of the vitamin D receptor (VDR) in human keratinocytes, blocking the action of vitamin D on keratinocyte differentiation.

This study found that pepsin digestion was more effective than trypsin at identifying keratin-associated proteins in human hair shafts and confirmed that trypsin introduced a bias in the analysis of protein composition that pepsin can correct.

Hair keratin protein might help heal mouth wounds faster.

This study found that applying HHORSC exosomes may enhance the hair inductivity of dermal papilla cells, potentially improving treatments for hair loss.

This study found that platelet-rich plasma significantly enhanced the viability, as well as the expression of alkaline phosphatase and versican, in human hair dermal papilla cells compared to controls.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

In this case report, a 36-year-old patient undergoing secukinumab treatment for psoriasis experienced both hepatitis B reactivation and hair discoloration, suggesting a potential link between these effects, though further studies are needed to understand this relationship.

This study found that human placental extract significantly improved melasma, chronic ulcers, and alopecia areata without major adverse effects, suggesting its effectiveness and safety for these conditions.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

This study found that a hair conditioner using peptides from Pneumatophorus japonicus heads improved damaged hair's structure, gloss, and smoothness more effectively than a commercial wheat protein conditioner by increasing amino acid content and interacting with hair keratin.

This review identifies genetic mutations associated with congenital hair loss disorders in Japanese populations, particularly highlighting common LIPH gene mutations linked to woolly hair/hypotrichosis, and reports no new clinical results.

Scientists made nanoparticles from human hair proteins to improve drug delivery.
