In this study, Bioactive Collagen Peptides supplementation increased hair follicle cell proliferation and improved hair thickness in healthy women over 16 weeks compared to a placebo.

This review explores the complex interrelationships among different properties of natural hair fibers and underscores the need for a holistic taxonomy to improve data interpretation across disciplines, but it reports no new experimental results.

This study found that male androgenetic alopecia patients had significantly lower serum zinc levels and suboptimal biotin levels compared to healthy controls, suggesting the potential value of zinc and biotin supplementation.

This study reports zinc and biotin deficiencies leading to hair loss and skin issues in a teenager after pancreaticoduodenectomy, highlighting the need for supplementation to prevent long-term damage.

This study found that depression and chronic stress are highly correlated in pregnant women, suggesting different stress mechanisms modulate hair cortisol levels in depressed versus non-depressed individuals.

This study suggests that simple absolute threshold monitoring rules for compliance using the biomarker DHT perform similarly to more complex methods in the Prostate Cancer Prevention Trial.

This study found that girls with prepubertal simple hypertrichosis had significantly higher plasma levels of dihydrotestosterone compared to controls, which does not align with other androgen markers and warrants further investigation.

This study reported that biotin treatment improved or cured fur and skin conditions in most dogs, though the response varied by breed.

This study found that a multifunctional hydrogel dressing enriched with Cu-MOF and tannic acid significantly improved full-thickness wound healing in rats, reducing the wound area to only 1.6% and promoting re-epithelialization, neovascularization, and hair follicle formation.

This study found that aged C57BL/6 mice sub-strains exhibit distinct aging patterns, including differences in survival rates, body weight changes, and disease incidences, providing valuable insights for geriatric research using these mice models.
