My Doctor Says to Take One Proscar Every 5 Days for Treating Hair Loss

Hey Dr. Rassman I have some question

1. My doctor says that to take one pill of 5mg finasteride (proscar) every 5 days amounts to take 1mg finasteride each days, i’m not sure he’s right, what do you think about it?
2. I have less than 20% of miniaturized hair all over my scalp (about 6% all over), but miniaturized hairs have not an equal diameters. Do you considered this as a MPB?
3. When consider you that the MPB is stabilized? No more miniaturization on the scalp?
4. Is the finasteride bad for the body-building (whithout steroids or anything else of course)?

thanks!

1. I hate overruling other physicians, but your doctor may be wrong. To treat hair loss, you need to take 1/4 pill of Proscar a day (ideally it would be 1/5 pill, but that is not practical to split into 5 equal pieces). If you take one full pill of Proscar (finasteride 5mg) once every 5 days, it would be be out of your system in 24 hours. There is some tissue (hair) fixation that may last 5 days, but that is not well documented and what it means is less documented.
2. If you have less then 20% of miniaturization over your scalp then you should not be on finasteride (Propecia / Proscar), because you don’t have male pattern baldness (MPB).
3. It is normal to have 10 to 20% miniaturization on your scalp as these may represent vellus hairs, not miniaturized hairs.
4. Finasteride has nothing to do with body building or exercise.
