Evaluation of Hair Growth Promoting Activity of Petroleum Ether Extract of Abrus Precatorius Linn. on Wistar Albino Rats

In 2019, a study was conducted to evaluate the hair growth promoting potential of petroleum ether extract of Abrus precatorius leaf. The study found that the extract showed significant hair growth promoting activity at a dose of 300 mg/kg, comparable to that of 2% minoxidil, a common hair growth treatment. The parameters considered included time taken for covering a bald patch, length of hair produced, percentage of hair follicles in anagen and telogen phases, time of hair growth initiation and completion, and level of minerals in blood. After 30 days of treatment, the time taken for covering the bald patch, hair growth initiation and completion time, and quantitative hair growth were found to be comparable to that of the standard drug. An increase in the percentage of hair follicles transitioning from the telogen phase to the anagen phase was also noted.
