IT's all in the mind really, though I wouldn't knowingly use one myself. I am not defending it, but obviously it has to be thoroughly cleaned, if not residual 'tell tale' signs are obvious; these people may be unscrupulous, but not stupid. Natural wigs are afterall re-cycled human hair. Come to think of it, it is a good idea from a purely technical point of view because condoms, for obvious reason, are made of high quality rubber and have been tolerance tested to a high degree of elasticity and so can be more lasting and stretchable than ordinary rubber band, and they do come in a variety of colors and textures; I understand some even glow in the dark; why that is an advantage when used for it's original purpose, I would never know, nor do I wish to find out.
I'll rather be happy than right, anytime.
