Experimental Study on the Effects of Spironolactone on Human Hair Follicles In Vitro
January 2006
TLDR Spironolactone does not change hair growth.
In the 2006 study examining the effects of spironolactone on human hair follicles in vitro, researchers found that varying doses of spironolactone did not significantly affect hair follicle growth or DNA synthesis rates, as measured by the incorporation of ~(3)H-TdR. The study concluded that spironolactone neither enhanced nor inhibited hair follicle growth. The specific number of hair follicles used in the study was not provided in the summary.
