Hello I have been using Propecia 1mg for 8-9 years.Recently I noticed that the benefits of the drugs slowly started to wear off.My hairs begun to miniaturise again.I was told that by increasing the dose to 2.5mg Proscar a day I could slow down or stop the miniaturisation process.I did increase the dose & after 2 weeks I noticed that the balding stopped. However,after 3 weeks I developed an incredibly oily scalp.Can the increase in dosage be responsible for the increase in sebum? I know dobbo is using 2.5mg,have you had similar problems mate ?
