How effective is Finasteride?
According to clinical trials, finasteride prevents further hair loss and promotes hair regrowth for 90% of men who take it. It is considered to be one of the only effective hair loss treatments on the market. For most men, noticeable effects appear after 3-6 months of daily use. Thicker, fuller hair and a better hairline may take up to 12 months to see.
What is Finasteride?
Finasteride is a prescription-only medicine belonging to a group of drugs called 5-alpha reductase inhibitors. Finasteride at a 1mg daily dose is used to treat male pattern hair loss in adult men. Male pattern hair loss is a common condition that can result in thinning hair, reduced hair growth and gradual balding.
Finasteride is also available as a 5mg tablet (Proscar) used to treat benign prostate hyperplasia in men. There is no evidence to show that taking more than 1mg of Finasteride a day is faster or better at treating hair loss.
How does Finasteride work?
Finasteride blocks the enzyme 5-alpha reductase that converts testosterone into dihydrotestosterone (DHT). DHT is the hormone that causes hair follicles to shrink and hair to regrow at a slower rate. This consequently leads to hair loss and balding. A single dose of Finasteride 1mg reduces DHT levels by 65% [1] in 24 hours.
By reducing the amount of DHT in the scalp, Finasteride helps halt hair loss and even reverses it in some cases. The hair follicles will be stimulated to grow new hair strands in more volume after an initial shedding phase. This is why it is important to continue taking finasteride daily for 3-6 months for any benefits to be seen.
If finasteride has not been effective after 12 months, continuing treatment is unlikely to bring further benefits.
What is the difference between finasteride and Propecia?
Propecia and Finasteride are the same medication. They both work the exact same way and are equally as effective. The only difference is that Propecia is the specific brand of Finasteride whilst Finasteride is a generic medication. This means Finasteride is generally cheaper than Propecia as you are not paying for the brand.
