Topical finasteride added to my routine with lots of shedding

I started topical Finasteride 5 months ago (fin/min 0.15%/7%), and after 5 weeks I started to shed HEAVILY so it’s been almost 4 months of continuous shed. I don’t know what to do. I have been applying Minoxidil for almost 10 years and the initial shed was never as bad as this. Most of the sheds last 1 or 2 months I’m reading. I don’t know if I will be losing everything, or if i should try a higher topical dose (I also tried 0.25% topical before for 3 months), oral fin and then at what dose?

Topical finasteride goes systemic, but the amount is not in your control. If you use the oral, then you have better control. The hair loss response to the finasteride tells you that it is working, so be patient.
