Do New Hairs Grow as Miniaturized Hairs?
No, finasteride does not produce miniaturized hairs. It may cause new hair to grow or make miniaturized hairs thicker.

How do you know this? Any evidence you can provide? Anecdotally on Reddit and hair forums – you read hundreds of posts of people “sprouting new mini hairs” (ie at the hairline), after starting finasteride, minoxidil, and more recently – dermarolling. These hairs may not necessarily be fully miniaturized – but they certainly are thinner than other terminal hairs.
How do you account for this?
I have seen patients with significant miniaturization placed on finasteride and then upon re-examining them, I saw less miniaturization as hair seem to become thicker in the same areas I examined.
