Proscar EOD and DHT serum levels advice

[diffusing]

So I'm 22 yrs old and a diffuse thinner, everywhere. Around the ears, back, top, sides. Hair really began to thin and shed in August of 2010. After going the natural route of saw palmetto and realizing that didn't work, i started proscar at the beginning of Jan 2011. I split the proscar 8 times and take 1/8 every MWF. My serum DHT levels before getting on it were 30 ng/dl, average range is 25-75 ng/dl. After a month on 1/8 proscar MWF, my levels are now 20 ng/dl. It is now around the 2 month mark and I still have yet to see improvement and my hair continues to shed massively. Maybe 200 a day.

Does this mean propecia/proscar won't work for me? Should i up the dosages? Wait it out? Anyone experience something similar?

Any advice is appreciated, thanks.
