My friend, who I am telling not to take steroids is not listening to me. He has a full head of hair and has no idea what it feels like to be in our position. He took a cycle of steroids and noticed hair shedding. He did look a little thinner than usual...my question is...once he gets off the cycle of steroids...would his hair grow back to normal or would he have accelerated his mpb? He was asking me if he could use some of my proscar to help with the hairloss...is that possible?
