I’m a Late Bloomer — Is It OK to Take Propecia?

I started thinning in one temple at 18 and was prescribed rogaine and biotin supplements. At 20 the entire top started thinning (especially in the frontal hairline area) and I am now nearing 21 and considering propecia, however, I am hesitant to start at such a young age for a couple reasons. I am a late bloomer with no facial hair and am constantly told that I look much younger than I am. I have two questions: 1) Will propecia effect my body’s development including facial hair? and 2) Is it more likely that something other than MPB could be affecting my hair because my body is so early in its development? I enjoy your blog and would appreciate any help you can give me. Thank you

It is possible (but not probable) that Propecia will slow down body hair growth. That has not been my experience. I really don’t know the answer to your perceptions of being a “late bloomer”. Some men don’t grow facial hair well at all, but at 20 years old your body is not early in development. I can’t say for sure what you’re experiencing without an exam, but from your brief one-line description, it sounds like MPB (frontal hair loss, top thinning). Propecia is a prescription drug, so discuss your concerns with your doctor.
