A lot of those hair pieces are either retextures and/or tacky e.g.
And even the good options sometimes have addons tacked on that should be separate accessories that may ruin the style you’re trying to achieve:
Even including all of the hair options though (~400 if all of those 6 pages are hair), they’re not very diverse. Take a look at some of the hair mods Bethesda games see and compare that that to the ROBLOX catalog. I think the popular ones typically offer ~100 hair models, but provide way more diversity than ROBLOX does. Even mods that include only 30 provide a better selection.
