TLDR Cayenne leaf extract can effectively promote hair growth.
The study investigated the effects of cayenne leaf extract on hair growth in mice using a Completely Randomized Design with 5 treatments and 4 repetitions. The treatments included a negative control, a positive control with commercial hair extract, and three concentrations of cayenne leaf extract (10%, 20%, and 30%). Results indicated that the cayenne leaf extract significantly increased both the length and amount of hair in mice, with the 10% concentration being the most effective. The findings suggested that cayenne leaf extract has potential as a hair tonic.
