How Long Do I Have to Wait to See a Value for the Finasteride I Am Now Taking?

I’ve taken steps to combat hair loss that I’ve been experiencing since about 20. I’m 23 currently, and about 2 months in the big 3 + Dermarolling. Recently, I’ve been experiencing shedding of very thin and small hairs. Is this a positive sign that they are going to be replaced by thicker hairs? Lastly, is there any signs of regrowth on my hair pics above? I’d like to say I see small progress for 2 months, but it could be hair length factors/lighting.

You have to wait a full year to see 80% of the value of the drug Finasteride. Sometimes, shedding is reported for the first two months as in your case. I don’t think that the Dermaroller adds value. You could add topical Minoxidil nightly to accelerate the effect. At your age, this combination of medications should work.
