Male Pattern Hair Loss Treatment Results
The earlier, the better
Male pattern hair loss is progressive, so the earlier you start taking PROPECIA, the better. The 5-year clinical study demonstrated the benefit of treating hair loss earlier with PROPECIA.

PROPECIA can work over the long term only if you continue taking it. If you stop taking PROPECIA, you will likely lose any hair you have gained within 12 months of stopping treatment.

PROPECIA was developed to treat mild to moderate male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head) in MEN ONLY. There is not sufficient evidence that PROPECIA works for receding hairlines at the temples.

Important Information About PROPECIA

Women who are or may potentially be pregnant must not use PROPECIA and should not handle crushed or broken PROPECIA tablets because the active ingredient may cause abnormalities of a male baby’s sex organs. If a woman who is pregnant comes into contact with the active ingredient in PROPECIA, a doctor should be consulted.
PROPECIA tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed.
PROPECIA will not work faster or better if you take it more than once a day.
aTHE FACTS ARE IN
 A 5-year clinical study demonstrated the effectiveness of PROPECIA.
  • 9 of 10 men who took PROPECIA had visible results—either regrowth of hair (48% [134 of 279]) or no further hair loss (42% [117 of 279])—vs 25% [4 of 16] who took a placebo (sugar pill), according to an assessment of photographs by an independent panel of dermatologists.
  • 2 of 3 men who took PROPECIA regrew hair, as measured by hair count. All of the men in the study who were not taking PROPECIA lost hair.
  • A majority of men who took PROPECIA were rated as improved by doctors—77% (210 of 271) vs 15% (2 of 13) of men who took a placebo.
  • A majority of men who took PROPECIA reported that their bald spot got smaller, their hair loss slowed down, and the appearance of their hair improved.
When to Expect Results
You will need to take PROPECIA for as long as you want to grow or maintain your hair. It's important to stick with PROPECIA for at least 12 months to judge how well it’s working for you.
