Guys.....This is my situation I'm currently taking propecia 2mg a day for about 4 yrs now. about 6 months ago my scalp has become very sensitive. I get this pinching sensation like someone is sticking needles in my scalp followed by itching and then leads to hair loss. I'm not on any topicals and I rotate shampoos often ( PM green tea and nizoral ). I cant see anything on the surface and I dont know what could be causing it. Can someone plz help. also I have oily hair can someone plz rec. a solution Thanks
