My story -
I got prescribed to Propecia and took that for about a month between mid-feb and april/may 2010..then switched over to finasteride 5MG and have been cutting that into fourths with a pill cutter. I took just 1.25MG of fin daily for a few months but still had some itch on my scalp so i upped the dose to 2.50 daily and the itching has stopped.
I've considered bringing the dose back down now to 1.25 because I don't want to build a tolerance to that dose. I also use prescribed 2% Ketaconazole shampoo twice a week, which I'm pretty sure is the same as Nizoral, i use this WITH A CONDITIONER because I think using the shampoo alone dries/irritates my scalp..i let both the shampoo and conditioner sit on my scalp 5-10 min each. On top of all this i use rogaine foam where my hairline is receding and have had low expectations of hair regrowth and also no results.
I am currently not suffering anymore hair loss or receding and the itching has stopped. Wish i would've started this a couple of years earlier when the hair loss begun but didn't start right away because of all the horror stories I read. I haven't experienced any sides except for minor ball ache after i upped the dose to 2.5mg of fin..but that went away after a couple weeks. I'm still kind of worried for the future but hope my hair loss has been completely halted for a few more years and hopefully some more regrowth can occur
