Abstract

Recently topical use of 2% Ketoconazole solution has been reported to have a therapeutic effect on androgenic alopecia. Minoxidil is a vasodilatory medication used primarily as antihypertensive drug. It was discovered to have the side effect of hair growth and reversing baldness. Tretinoin is commonly used topically for acne treatment and in the treatment of photoaging. It is used by some as hair loss treatment.

OBJECTIVE:

To compare the stimulatory effect of Ketoconazole, Minoxidil, and Minoxidil with Tretinoin on hair growth in a mouse model.

MATERIALS AND METHODS:

Coat hairs on the dorsal skin of seven weeks old male mice were gently clipped and then stained by using commercial dye. These mice were divided into four groups each of five treated with topical application of ethanol 95%, Ketoconazole solution 2%, Minoxidil solution 5%, and Minoxidil with Tretinoin solution 0.1%, respectively. The drugs were applied once daily for three weeks, the clipped area was photographed, and the ratio of regrown coat area was calculated.

RESULTS:

The results demonstrated that Ketoconazole, Minoxidil, and Minoxidil with Tretinoin had a significant stimulatory effect on hair growth compared with the control group and Minoxidil was the most effective drug among them.
