I saw a report on this in the UK press (The Guardian, I think). The proclamation that all Indian wigs (whether made from hair offered as part of a Hindu devotional oblation, or for strictly commercial reasons)are non-kosher was a bit drastic, but intended to prevent inadvertent transgressions by orthodox Jewish wig-owners. There's been a run on snoods, but because this rabbinical ruling has seriously adverse commercial implications for a multi-million dollar industry, I understand that consideration is being given to the question of whether hair harvested in India for non-kosher religious purposes can be distinguished from strictly commercial and possibly kosher supplies.
