Please help - Finasteride shedding/thinning my hair after 3 weeks

[yjr1991]

Guys,

I need your help desperately!

My history -

27 yo Male. I started losing hair on the crown region couple of years ago. Consulted a hair transplant doc and he recommended Finasteride 1.5 mg/day. Shaved my head on March 14 2019 to see progress and started Finasteride 3 weeks ago. Now, I am not shedding my regular hair but shedding some small white, transparent hair. I also see that my overall hair has thinned. I am scared to continue Finasteride. Your inputs would be valuable here. Is what I'm experiencing normal?

PS - I haven't had any other sides.
