April 2002 in “Animal Science” The study investigated the effects of intradermal spermidine injections on wool follicle growth in Merino lambs. Three groups of eight lambs received different concentrations of spermidine injections on a small skin patch, with saline as a control on the opposite side. Results showed that spermidine increased the concentration in the skin and stimulated cell division in the follicle bulb, with higher doses leading to greater increases. Fibre length growth rate was also higher with spermidine, although fibre diameter did not change significantly. The study concluded that spermidine injections altered skin spermidine homeostasis, stimulated cell proliferation, and increased fibre growth.

February 1996 in “Journal of Investigative Dermatology” The study investigated the role of polyamines in hair follicle function and fiber composition in sheep. It found that inhibiting ornithine decarboxylase with alpha difluoromethylornithine altered fiber characteristics but did not inhibit wool follicle growth in culture. Conversely, inhibiting S-adenosylmethionine decarboxylase with methylglyoxal (bis)guanylhydrazone completely inhibited fiber growth, which could be reversed by adding spermidine, but not spermine. The study concluded that polyamines, particularly spermidine, were crucial for hair growth, as evidenced by the ability of spermidine to partially counteract growth depression in methionine-deficient conditions.
