Many think that viviscal will grow new hair. They buy it, don't grow new hair, and claim it's a snake oil. Do you guys even read the box!? It says promotes EXISTING hair growth.... Meaning it may thicken up EXISTING hair.
You can find a study which supports just about anything. Better to go to an excellent doctor with years of experience and real knowledge about what works and doesn't. I did and was told that 2 things work: minoxidil and finasteride. And everything else has little or no effect. I believe it.
