I agree. I think hair samples are one of the most overrated ways of determining
what's actually going on.
But it is interesting (and intriguing) to see how it all fits together. Or doesn't. You'd think by now there would be some consensus on what the moons are all about, besides the heavy medical terminolgy about the nail matrix. Isn't it odd that your son has moons, and you know him to be very healthy, while Zach does not, (and used to) and yet says he feels better than he ever has?
