“Precisely. The reason many poskim do not allow ANY sheitels is precisely because it can be mistaken for the wearers regular hair.”
So what???? What if the wearer’s REAL hair is really ugly? Does it make that hair any less assur to be viewed by a man other than her husband? No. It has nothing to do with the beauty or lack thereof, it would seem to me, but rather the fact that the hair acquires a new status of kedusha upon marriage. To explain my point in a more readily understandable venue, when askewd why we don’t eat bacon, we cannot say it is because bacon is horrible, tastes bad, is unhealthy, etc. Nope – it is delicious (so tells me my baal teshuva husband), but it not mutar for a Jew to eat – period! So we don’t eat it. A woman’s natural hair does not have to be ugly in order for us to have a chiyuv to cover it. Nor do we have to look ugly in the covering of it. It is just not mutar to show it to any man but the person for whose eyes it is intended.
