If it works, you won’t be able to regrow all of your hair, and it could take up to four months to see results. To keep any regrowth, you’ll have to use Minoxidil indefinitely.

Minoxidil is a topical medication administered to the scalp to promote hair growth and prevent hair loss caused by male and female pattern baldness. This is the most prevalent form of hair loss, and it is inherited.

Minoxidil is most effective in persons who have hereditary hair loss at the vertex of the scalp or women who have overall hair thinning on the top of the scalp. Minoxidil isn’t intended to treat a receding hairline or baldness in the front of the head.

Minoxidil has been demonstrated to be most beneficial in persons under the age of 40 who begin using it as soon as they notice hair loss. It won’t benefit folks who have already lost their hair.

Consult your doctor before using Minoxidil if you have a heart condition.

Studies on Clinical Efficacy

Minoxidil has been found in clinical research to regenerate hair in certain persons efficiently. 40% of males experienced moderate to dense hair growth on the top of their heads in the big clinical investigation that led to the drug’s approval in 1987. In a one-year observational trial, 62% of the 984 males who used 5% minoxidil saw a decrease in hair loss. In terms of hair regeneration, 16 percent of participants said the medicine was “extremely effective,” 48 percent said it was “effective,” 21 percent said it was “moderately effective,” and 16% thought it was “ineffective.” The negative ramifications were limited.

Clinical trials on women were also conducted. In a double-blind study, 19 percent of women aged 18 to 45 who used Rogaine for eight months reported moderate hair regrowth, whereas 40% saw no change (compared to 7 percent and 33 percent for placebo, respectively).

Negative Effects

Minoxidil is thought to be safe. Minoxidil side effects are usually minor. Among the most common are:

  • irritated scalp
  • hair growth in the areas around your brow, for example
  • alterations in the structure or color of the hair

  • weight gain that is abrupt and unexplained
  • dizziness or faintness
  • Swelling of the hands and feet
  • chest discomfort
