Latisse v Rogaine for Beard?

I have good coverage on my beard (no bald spots). However some parts of the beard grow in thin while others grow in thick. Which leaves to a messy appearance. I have read that Rogaine can increase the thickness of hair. However the side effects are off putting. I have read into Lattise as an alternative which doesn't have any blood pressure side effects. Can I use Lattise to help thicken my beard hairs in certain areas to create more even growth as effecively as rogaine?
