Will finasteride work on my crown hair loss? I am 27 years old (photo)

Finasteride is more effective against the crown than elsewhere on your scalp. The photo shows that the hair loss starts above the swirl and moves to the frontal area. It is worth a try using finasteride, but if you use it, stay the course.  Usually, the crown is more responsive to finasteride at any age than the frontal hairline.
