Does Finasteride stop or only slow down hair loss?

[inspects]

I've read conflicting things about this. On one site a doctor is saying that it only slows down, not stops hair loss.

One doctor really isn't a fair comparison based on most doctors. I think most doctors claim the same as the manufacturer, the medication slows or stops hair loss for most individuals experiencing male pattern baldness.

Then I see studies done over 10 years that show a very high percentage of men see no further loss when taking the drug, and some testimonials from people saying they've had no further loss.

Consider me one of the fortunate people who can honestly say the drug has stopped my hair loss, or rather slowed it to a snails-pace based on what is considered normal hair loss. Everyone sheds hair before regrowth begins in the natural process of hair growth and hair loss.
