“Natura hair wigs are worse if they look like uncovered hair which can bring to hirhur”
Sources please, as far as we are aware “hirhur” only pertains to what Chazal assered. Chazal prohibited only ones OWN hair as per REMA, M”A, Pri Mgadim, MB and many others.
You can not invent any new gezeros, and if so why are girls uncovered hair permitted?
