For that, you need lights from the sides as well as from above. A ring light at the front is also a good addition, but not as necessary.
My setup is like this:

This is a folding photo studio (but set up permanently in my modelling room), with lights above and on each side, shining through the white fabric so the shadows aren't as harsh. The lights on both sides point up somewhat, which also helps reduce the harshness of the shadows. Also, these are
white lights, not blueish like your fluorescent tube probably is.
I take photos through the ring light at the front, which I added because Aldi had them cheap a few years ago — the flexible mount I bought for it cost more than the light did
