February 1972 in “Proceedings of the National Academy of Sciences” This study found that a unique transglutaminase in guinea pig hair-follicles, distinct from liver transglutaminase, likely plays a role in forming protein cross-links via ε(γ-glutamyl)lysine bonds.
25 citations
,
December 1973 in “Biochemical Journal” 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.

November 1994 in “International Journal of Dermatology” This study found that while the combination of oral propranolol and intradermal injections in guinea pigs led to psoriasiform changes, it did not fully mimic psoriasis.
12 citations
,
February 2017 in “International journal of developmental neuroscience” This study observed that reduced in utero exposure to the neurosteroid allopregnanolone increased anxiety-like behavior in female guinea pigs during the juvenile period without affecting long-term allopregnanolone levels.

September 2024 in “Veterinary Medicine and Science” In this study, researchers found that a single oral dose of afoxolaner was safe and effective in treating a severe case of Trixacarus caviae mange in a guinea pig, achieving full remission of clinical signs and mite eradication within 4 weeks without needing repeated treatment.
August 2004 in “Veterinary Dermatology” This case report describes two guinea pigs infested with Acarus farris mites, which were successfully treated with Phoxim and removal of contaminated hay, leading to rapid resolution of skin lesions and alopecia.
February 2025 in “Eduvest - Journal Of Universal Studies” In a laboratory study on guinea pigs, Kepok banana peel extract serum at a 30% concentration showed promising effectiveness for hair growth, with results close to those of 5% minoxidil®, suggesting it could be a viable hair care alternative.
