January 2006 in “Chinese Journal of Aesthetic Medicine” This study found that exogenous zinc improved the viability of ultralong random skin flaps in Wistar rats by reducing oxidative damage and increasing protective protein levels.
January 2000 in “The Journal of Trace Elements in Experimental Medicine” In this case report, an 11-year-old girl with acrodermatitis enteropathica experienced a complete resolution of symptoms following oral zinc therapy, highlighting its effectiveness in managing this condition.
March 1997 in “Medical Molecular Morphology” Zinc deficiency causes early scalp hair damage that recovers slower than skin symptoms.
March 1996 in “Proceedings of the British Society of Animal Science” This study examined how different forms of dietary zinc affect the dimensions, weight, and zinc content of dog hair to evaluate coat condition.
March 1996 in “Proceedings of the British Society of Animal Science” This study examined how the form of dietary zinc affects the dimensions, weight, and zinc content of dog hair, which are considered indicators of coat condition.
March 1995 in “Proceedings of the British Society of Animal Science” This review discusses zinc's role in dog metabolism and suggests that zinc from amino acid chelates might be better absorbed than from inorganic sources, but reports no new experimental results.
March 1995 in “Proceedings of the British Society of Animal Science” This review discusses zinc's role in dog nutrition, emphasizing that zinc absorption may be improved when provided as an amino acid chelate rather than an inorganic source, but reports no new results.
January 1992 in “Journal of Oriental Neuropsychiatry” This study found that zinc, copper, and chromium levels were significantly lower in the hair of Korean individuals with schizophrenia compared to healthy individuals.
This study found a correlation between zinc levels in hair and serum, and alkaline phosphatase activity in acne phlegmonosa and alopecia areata patients.
March 1986 in “Fed. Proc., Fed. Am. Soc. Exp. Biol.; (United States)” This study found no convincing evidence that marginal dietary zinc intake caused changes in blood fractions, despite signs of zinc deficiency in the low zinc group of rats.
February 1981 in “Kazan medical journal” This article reviews the research history linking zinc deficiency to hair loss and mucous membrane changes but reports no new clinical results.
November 1979 in “PubMed”
April 1978 in “Pediatric research” This study found that zinc levels in hospitalized patients with significant weight loss did not correlate with taste perception or vitamin A status, even in those with reduced taste acuity.
January 1978 in “Yukagaku” This study found that using a zinc pyrithione-containing hair rinse significantly reduced dandruff and itching, with effects linked to the amount of zinc pyrithione residue on the hair.
March 1963 in “Sangyo Igaku” Women generally have higher levels of iron, copper, and zinc in their hair than men, with differences increasing with age.
March 2023 in “International Journal of bioprinting” This study found that a bioprinted hydrogel scaffold with zinc and silicon ions significantly activated hair follicle stem cells and enhanced blood vessel formation, promoting hair growth in mouse wound models.
January 2022 in “Social Science Research Network” This study demonstrates that a newly developed nanocomposite microneedle patch, releasing copper and zinc ions along with quercetin, effectively promotes hair follicle regeneration in androgenic alopecia by targeting various pathophysiological aspects of hair loss.
January 2020 in “Skinmed” Zinc levels are not significantly different in people with hair loss conditions like Androgenetic Alopecia and Alopecia Areata.
April 2016 in “Journal of The American Academy of Dermatology” People with hair loss have low zinc levels; zinc supplements and laser therapy may help.
January 2016 in “American Journal of Clinical and Experimental Medicine” This study found that men with androgenic alopecia had significantly lower hair zinc levels compared to controls, but no significant difference in blood zinc levels was observed.
