Hello, I am currently going through another horrible shed with my hair. Normally I start a new medication (tried spironolactone, progesterone cream, cyproterone acetate and now finasteride) and the excessive shedding stops within a day or two. I started finasteride about 2 weeks ago and the shedding is getting worse! I've stopped counting at 250 hairs a day! How long does the excessive shedding cycle last with everyone else?
