Thought about that but honestly, other than some burning during the treatments and pretty dry hair, I haven't had any adverse effects.

I actually got the results of my PDT 90 today - NEGATIVE !!! - That takes the stress down a notch or two. Haven't gotten the final info on my real test, but still looking at no later than Tuesday next week. May have the results from Quest by then so I could feel pretty good walking into this one now.

Anyone ever seen info on someone passing PDT 90 but fail lab test?
