The topical application of minoxidil may achieve millimolar concentrations in the skin. We investigated whether millimolar minoxidil could induce vascular endothelial growth factor (VEGF), a possible effector for minoxidil-mediated hair growth, and how it occurred at the molecular level. Cell-based experiments were performed to investigate a molecular mechanism underlying the millimolar minoxid...
The object of the present study was to determine whether deoxycorticosterone acetate (DOCA)-salt hypertension can be produced in rats in the presence of low total peripheral resistance (TPR) induced by long-term administration of minoxidil, a vasodilator. The rats were divided into four groups: sham-control, DOCA-salt, minoxidil, and DOCA-salt with minoxidil. The rats in both DOCA groups had DO...
BACKGROUND To pical minoxidil solution 2% stimulates new hair growth and helps stop the loss of hair in men with androgenetic alopecia and women with female pattern hair loss. Results can be variable, and historic experience suggests that higher concentrations of topical minoxidil may enhance efficacy. OBJECTIVE The purpose of this 48-week, double-blind, placebo-controlled, randomized, multic...
Minoxidil directly promotes hair growth via the stimulation of dermal papilla (DP) and epithelial cells. Alternatively, there is little evidence for indirect promotion of hair growth via stimulation of adipose-derived stem cells (ASCs). We investigated whether minoxidil stimulates ASCs and if increased growth factor secretion by ASCs facilitates minoxidil-induced hair growth. Telogen-to-anagen ...
Although minoxidil has been used for more than two decades to treat androgenetic alopecia (AGA), an androgen-androgen receptor (AR) pathway-dominant disease, its precise mechanism of action remains elusive. We hypothesized that minoxidil may influence the AR or its downstream signaling. These tests revealed that minoxidil suppressed AR-related functions, decreasing AR transcriptional activity i...
We have known for over 30 years that minoxidil stimulates hair growth, yet our understanding of its mechanism of action on the hair follicle is very limited. In animal studies, topical minoxidil shortens telogen, causing premature entry of resting hair follicles into anagen, and it probably has a similar action in humans. Minoxidil may also cause prolongation of anagen and increases hair follic...
The effect of minoxidil on lysyl hydroxylase activity and proliferation of human skin fibroblasts in culture was examined. Exposure of cells to minoxidil resulted in a specific loss of lysyl hydroxylase activity, the extent of which was dependent on the concentration of minoxidil from 25 to 500 microM and the duration of the treatment from 6 to 48 h. This phenomenon was unaffected by culture co...
Hypertension is a cardiovascular disorder that appears in more than half of the patients with Williams-Beuren syndrome, hemizygous for the elastin gene among 26 to 28 other genes. It was shown that the antihypertensive drug minoxidil, an ATP-dependent potassium channel opener, enhances elastic fiber formation; however, no wide clinical application was developed because of its adverse side effec...
Vasodilators used in chronic congestive heart failure are not optimal in that nitrates are predominant venodilators, prazosin is associated with tolerance development, and hydralazine produces chronic toxicity. Therefore, we studied the acute hemodynamic effects of a single dose of minoxidil in 18 patients with chronic left ventricular failure caused by ischemic or primary cardiomyopathy. Peak ...
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 ha...
