What is RK19 and the obvious question: does it really work?
Again and again, more products reach the market that do not reflect legal claims allowed by the FDA. In my opinion, the pictures on this site are not believable, which makes the site and the claims not believable to me. The pictures appear to have some scalp coloring in the after pictures, which to me appear as if there was an effort to deceive the observer. I may be wrong, but as a clinician, I hold to stringent standards. Everyone wants a magical cure to balding and this certainly does not look like it.
