Hello Peter,
Well I'm norwood 4.. So no need to get so worried about it what people will think or it will effect your live as you will get used to it. And yes I'm using Rogaine foam and i'm on my 3rd bottle (can) right now and yes it did stop my shed completely but all of sudden my hairfall has started again and i noticed usually its fine or small in length hair compared to my normal hair length.. I believe its normal and it will get better with time. Its a long fight against hair loss. Keep hope and stick to your routine.
Btw I also use Hair Max laser comb & have Propecia 1mg once a week.
