That's outrageous! My hair analysis cost $70.00. It was from Doctor's Data Lab. An analysis was included in the lab's report. Then my doctor and I discussed it on my next regular visit. There were no additional doctor's fees.
I'm really glad I did it. I was a little skeptical. But it showed I was almost off the chart low on sulphur and boron. And supplementing those has helped, and led to some research that has helped find other needs as well.
But that guy just seems to be in it for the money.
