Eh I was really not a fan of those bangs on Ro (or the goofy red headband for that matter). I'd rather just have the main look she had in the series.

Ok, so this took me on a deep dive into Ro's hairstyles lol.
Here's what I found:
She was in 8 episodes
She had the look above in the first 4.
She had a short, almost Vulcan haircut in "Cause and Effect", her fifth appearance.
Then she switched to the headband for a couple episodes, though the haircut itself was different. There was almost a full season between the two.
And, finally, the bangs look, which almost looks like her first one.
Personally I like the bangs, just because it's the only episode where she's wearing the DS9-era "current" Bajoran ridges without the extra upper piece, so she'd fit in better near Kira, BUT if I had to vote for one, I'd agree with the above post, because it was her most "common" look.
