This might be too late, but my stylist recommends a net if your hair is the kind of hair that will become fuzzy quickly. Remember when you were little and your edges would be bushy (as I called them, the fuzzies). Whenever I get cornrows or sewn in tracks, I have those same fuzzies I did when I was a little girl. So for me, I get the net, to help alleviate the *fuzzies*.
The care is the same to me.
