No. Minoxidil topical solution 2% will not work faster or better if used more than two times a day. Studies have been carefully conducted to determine the correct amount of minoxidil topical solution 2% needed to get the best results. More frequent use or larger doses have not been shown to speed up hair growth and may increase your chances of side effects.
Men’s Rogaine Extra Strength Solution is the liquid version of our top pick. It didn’t make our final cut because it includes propylene glycol, which causes irritation in roughly one-third of its users. With that said, Dr. Wolfeld finds that it can be even more effective in practical daily use. In his experience, “the solution can penetrate and get into your scalp a little bit better” than the foam — especially if you’re not taking the time and effort to apply the foam correctly. This seems crazy to us since the foam so quickly dissolved into a liquid in our tests, but if you’re worried, try a one-month supply of the liquid and make the switch to foam if you notice any irritation.
1. Minoxidil. It’s the only FDA-approved topical nonprescription medication that can claim to regrow hair — and it should be part of any hair-loss plan if you have serious thinning, says Rogers. Minoxidil has loads of research to back it, but it requires commitment. If you quit using it, your hair will start to lose ground again. Use a 5 percent strength, like Women’s Rogaine 5% Minoxidil Foam ($30), once daily to see results in three to four months, says Rogers.
The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.
