Same boat, except 2nd shed. Its been like this for almost 4 months so I think its due to other factors (minor changes in regimine) b/c follicles shouldn't be "dormant" for this long, unless something bad is going on.
I know the dutasteride can only help, regardless of how severe the shed is. Its the lack of regrowth of those shedded hairs that has convinced me I need to get my regimine back in order.
Very important topicals to my earlier success were minoxidil FOAM (not this Spectral crap!), Tricomin, Retin-A, and (possibly) spironolactone cream (on temples/hairline).
