You always say at the 8th – 9th month mark you should see Propecia’s regrowth/thickening of hairs. If you haven’t seen anything by then does it mean there is no possibility of thickening of miniaturized hairs or regrowth after that? I read that Propecia can take up to 1 year to see its benefits and some say up to 2 years (I personally doubt that), so what’s the deal here?
If you follow the process with miniaturization studies (see here) then you can state categorically that it is not thickening up the hair shafts. I don’t always say you’ll see regrowth… but the drug almost always works on preventing or slowing hair loss in those genetically prone to it.
