Unless you're rich enough that all your clothes are cotton/linen/silk, tumble dryer fluff is mostly man-made fibres, which melts rather than catching light and contains toxic chemicals.
Hair also frizzles rather than burning. It might work if you had a duck ton of it I suppose, but it's not sustainable is it, unless you live in a commune of hair metal fans.
And the bubble wrap thing - I've tried that in my bathroom, which is an extension on my 1859 house and has no radiators or double glazing. It absolutely doesn't work.
