I have followed the trials and i recontact most of them last week (about 3-4 months past second batch of trials).
Again, no sides where reported, not a single one.
Although regrowth is NOT expected, some have clear indications that hair loss has reduced considerably. Less hairs in the shower and pillow.
If you are on Finasteride and happy with it, stay on it. If you have second thoughts about the Safety of propecia or you have sides from it, Keratene Retard is a good solid alternative.
I will try to provide updates from time to time.
