Buzzing Vs Longer Hair

[redy]

If my hairline thinning leaves the appearance of a thinning hairline at the roots, but the follicles are still thick enough in majority to maintain a normal appearance at the ends of the follicles, would buzzing it down shorter hide this thinning root appearance?

I don't really have any way of knowing unless I buzz it down, but I can't put it back on if there is no improvement :P
