What is the best way to style curly hair for men to prevent hair loss?

I have quite thick curly black hair and over the past year I’ve noticed it getting a little thinner around the front and back. This is mostly apparent when I wear my hair down (like Tom Welling), however when I’ve kept it up (which looks something like an afro) i’ve noticed less hair loss.

I don’t know if there’s a link between wearing your hair up and preventing more hair loss this way or not, but I would love to find out what the best hair-maintenance styles for men with curly hair are in light of the above
