Uneven hair distribution, issue?

Hey Everybody,
Does anyone know the cause of the next behavior of particle system? I have two same objects, one of which is rotated on x and z axis. Rotation and scale is applied. Both objects have the same particle system.
-No children.
-Even distribution is checked.
Issue: on one object have more hair from above than on the other.
Is there a solution to make distribution over two objects the same?
