I'm having no issues with my hair. I have had considerable regrowth on my crown while on finasteride, and Dr. Gabel fixed my temples where my hair wasn't going to fill in. I haven't noticed any shedding since starting Finasteride and Spironolactone in May of 2016, only regrowth.
I was on 5mg Finasteride, 200mg Sprionolactone, and 20mg/2weeks of Estradiol Valerate during my hair restoration procedure. Dr. Gabel did not see a need for me to stop any of them during my surgery or recovery.
I haven't noticed any of the adverse "side effects" mentioned online with Finasteride. With how well my hair restoration went, I've been doing quite well. My results have given me confidence and a better outlook on my future.
