I have never had dandruff in my life! Noticed flakes a couple of months ago and switched shampoos. Tried a few expensive ones from the “organic health store” which usually carries everything I want and need but none helped. Yesterday, after shampooing, I dipped my fingers into your colloidal silver and rubbed it into my scalp—did the same thing this morning. It is now 1:00 p.m. and not a flake in sight. I guess I am one of those skeptics who needs absolute proof. Well now I have it.
