Effectiveness
Improved growth usually begins after about three months and is usually noticeable by 4-6 months. The maximum benefit is observed in 1-2 years. At the end of 5 years, men taking Propecia / 1 mg finasteride tablets have a 90% chance of having more or the same amount of hair with which they started. This compares with 25% of men not taking Propecia / finasteride 1mg (see study details).
Who benefits
Men at any stage of men’s hair loss are likely to benefit.
Propecia / finasteride 1mg is most effective for hair loss in the upper part of the scalp (top).
Propecia / finasteride 1mg has not been shown to:
- Reverse retreating frontal hairline.
- Reverse hair loss that is only in the areas of the temple (the area on the sides of the forehead).
- Restore hair to completely bald areas.
Clinical studies were performed in men aged 18-41 years with mild to moderate hair loss, but not complete hair loss.
The best results of Propecia / finasteride 1mg treatment are observed after two years, so hair growth is likely to be more dense.
Cautions
- If hair loss was rapid and recent (less than a year), or where there are symptoms of serious illness – such as unexplained weight loss, fevers, persistent diarrhea or excessive fatigue – you should consult a doctor.
- When hair loss is broken or irregular, or the hair comes out in clumps, or there is inflammation on the scalp, the scalp should be examined.
- Blood tests performed to detect prostate cancer (PSA) can give misleading results when taking Propecia / finasteride 1mg.
- If treatment is stopped, the beneficial effects begin to be reversed by six months and return to the beginning by 9 to 12 months.
- Pregnant women should not contact Propecia / finasteride 1mg tablets.
Side effects
Decreased libido and erectile dysfunction are possible. Some men have reported episodes of depressive illness and suicidal thoughts. See leaflet for a full list of side effects.
If low mood or depression occurs, stop treatment and consult your doctor immediately.
