I am a diffuse thinner. I underwent a treatment similar to this. Fat cells were extracted from my body through minor liposuction in my midsection. Stem cells were derived from this, and a mixture of stem cell medium and PRP was injected into my scalp. Close up pictures of my scalp were taken before and after (one year apart) so that they could measure changes in hair density and thickness. Not a damn thing happened, except that I was out $5k. I was also using minoxidil and finasteride during this period.
