question about finasteride (dose it stop hair from growing)

[hair questions]

Has anyone ever noticed if taking Fin actually stopped your hair from growing? Seems like I can go for several months without having to get a trim since I started taking Fin about 13 months ago. Before I would have to get my hair trimmed about every 3 months because it grew fast. Now I can go 5 or 6 months without seeing much growth. Is this normal with taking Fin?
Thanks
