I'm inclined to agree. I can't count how many times I've been ask to give a definitive answer about one aspect or another surrounding WTA. Those who know me around here know that definitive answers come few and far between. It's one thing to say that I suspect something is true and quite another thing to say that something is true. My advice is to be very wary of anyone who claims to know the truth about these issues. They're more than likely full of it and usually full of themselves.
Wait I thought you said this stuff will make my hair grow.
