In my clinic, for hair loss cases, I do NOT apply non-approved injectable treatments, and the reason is that I don’t believe there is any scientific evidence that could personally convince me, as a doctor, that it’s worth drawing so much blood from my patient every month just to produce an unknown number of hairs. I already have approved medications and techniques in my hands that I know will produce hair, and I know exactly how much hair they will produce — and there’s no need for me to draw blood or anything else.
