Yeah, I think that could be a factor. In cdnuts case, I think he had lyme prior to taking fin in the first place, not sure if he was balding or not during that time, but it is interesting to see b/c many of the herbs part of the protocol are known to increase glutathionine (like he shou wu for example) maybe not enough for hair growth recovery long term. I'm not sure about the light at end guy though never read his story
Most herbs actually bind glutathione. And increase glutathione enzymes, since they actually waste glutathione. same as steroids.
When you are toxic in stuff, and not enough glutathione recylcing, body has to make NEW glutathione from cysteine constantly and that takes the cysteine from your hair.
I mean people taking testosterone age, since they are taking testosterone which retains iron into the cell, and then estradiol goes up which retains copper into the cell
But Testosterone axis should only go up when thyroid and metabolism asks for it. Thyroid asks for estrogen, and that is how axis goes up.
but they do the opposite they take testosterone. and obviously it will make them copper toxic in the brain,
