Men may also experience some sexual and emotional side effects while taking it: In a study published in the June 2011 issue of The Journal of Sexual Medicine, Dr. Michael Irwig of George Washington University found as many as 92 percent of test subjects reporting problems in the bedroom. The study also reported that “the mean duration of finasteride use was 28 months and the mean duration of persistent sexual side effects was 40 months,” meaning that side effects lingered long after subjects stopped taking the pill.
In our research and our conversations with experts, one name kept popping up repeatedly: Rogaine. As the first topical brand FDA-approved to help regrow hair (all the way back in 1988), Rogaine benefits from more than 20 years of clinical trials and consumer feedback. Rogaine was the first brand to offer a 5 percent minoxidil foam solution when it debuted Men’s Rogaine Unscented Foam in 2006, and virtually every treatment developed since (for both men and women) has been an imitation or derivation of that formula.
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.
