Natural Remedies for Gray Hair

I have to retract my Yea for fo-ti to a Nay. I was not meaning to be deceitful but I only figured out recently that it is due to where the flash of the camera is placed on my hair. The camera flash really picks up the gray, and if the camera is further away, my hair looks darker. However, recently I took another photo at exactly the same distance from a picture I took back in June and there was no change in the gray. I wish there was a way to post pictures on Earth Clinic to show what I mean. Guess I will have to put up with aging and the gray, such is life, Peace, Rena.
