Men's Rogaine Extra Strength Hair Regrowth Treatment (5 percent minoxidil) Review

Bottom Line

Reviewers consistently point to Men's Rogaine Extra Strength Hair Regrowth Treatment as the first line of defense against androgenetic alopecia (AGA), commonly referred to as male- and female-pattern baldness or genetic hair loss. It contains 5 percent minoxidil, which is also available generically. Rogaine must be applied twice a day, and any hair grown will be lost shortly after it is discontinued. It takes between four and nine months to see results. Possible side effects include excess hair growth on the face and body, but only a small percentage or users are affected (when treatments stops, so do any side effects).



  • Minimal side effects
  • Available without prescription
  • Slows hair loss for approximately 90 percent of users


  • Must be applied twice daily
  • Messy application
  • Not effective for everyone

Side effects

Can cause unwanted hair growth. Several Rogaine users posting to Drugstore.com complain of scalp irritation, but some say that switching to the original strength or another brand alleviates that problem. A few users complain of the odor associated with Rogaine while others claim that the smell disappears when the product dries. Experts say that some women may have unwanted hair growth, namely on the face, as a result of minoxidil usage, though it is a rare side effect and may be more likely to occur in women with a history of excess facial and body hair. Men's Fitness magazine points out that another uncommon side effect is chest pain, as minoxidil also comes in a pill for treating high blood pressure.

This informative article explains what causes hair loss and covers several topical solutions, including minoxidil, prostaglandins, fluridil, ketoconazole, spironolactone, melatonin and estrogen. The section about minoxidil is by far the most in-depth, and the authors cite multiple double-blind, placebo-controlled clinical studies that prove its efficacy in treating pattern hair loss.

Chan-Yi Bang et al., Aug. 13, 2013

This article focuses on a 1-year-old girl born with temporal triangular alopecia (TTA). Researchers treated the girl with 3 percent topical minoxidil, which proved effective in stimulating hair growth. However, each time the researchers discontinued treatment, her hair loss returned.

H.S. Shin et al., 2007

This report covers a study that compares the efficacy of 5 percent minoxidil to a combination of 5 percent minoxidil and 0.01 percent tretinoin. Results show that one daily application of the combination therapy yields similar results to those of 5 percent minoxidil applied twice daily.

E.A. Olsen et al., September 2002

Results of this study show that 5 percent minoxidil is superior to 2 percent minoxidil in producing more hair. The study also shows that the 5 percent strength yields an earlier response.

E. Arca et al., 2004

Results of this study show that women treated with 5 percent minoxidil have statistically superior results in regrowing hair compared to those using 2 percent minoxidil.

Holly C. Corbett, Not Dated

For this slideshow about the most effective types of hair-loss treatments, Holly C. Corbett consults Frederick Joyce, M.D., founder of Rejuvenate! Med Spa and member of the International Society for Hair Restoration Surgery. She places Rogaine last on the list, alongside Propecia, low-level laser light therapy, surgical implants, Nioxin shampoo and proper nutrition. Joyce points out that minoxidil is best for men who are trying to hang on to the hair they still have and that hair loss will resume if you discontinue use of the product.
