I was on Propecia and Minoxi for 8 months and then for last two months i didn't use them.Now i am back on them it has been close to 4 weeks,what i have noticed is that hair fall has increased to abnormal level,moreover i have lost my crown area to a large extent,few months back only crown top was visible,now whole crown is clearly visible,I have no idea wheather it's a normal shedding or what?
