I've been on Ru since April of 2014, I've been on minox since about September, Finasteride since February and nizoral for a couple years. In march 2015 my shedding stopped and I saw excellent improvement but I switched to minox foam and ever since my hair is shedding like no tomorrow. My crown regrowth has stayed in tact but a norwood 4a pattern has been under fire. I know shedding is generally a good sign but I can't tell what it's from.
