You can buy wheat grass juice powder and it will do the same. You do not have to grow it yourself. I used wheat grass juice powder and have noticed that my hair is coming in dark instead of gray. It does take time. It will not happen over night.
Wheatgrass
★★★★★
The best remedy for gray hair I have found is wheatgrass (juice or powder). When I started taking a combination of the juice and powder, I was shocked after a couple of weeks that I had large patches of dark hair growing. In about three months I could see the dark hair moving from the back of my head slowly to the front. Interestingly I found that the strands went dark from the roots to where my hair dye had grown out. There was no gray and then the dark started growing. I believe that the hair is like a piece of chalk you place in a glass of ink. When you drop it in the ink the whole thing turns dark. A strand of hair when given the proper nutrients also fill up. I gave my sister wheatgrass juice and powder and the same happened to her. It was more noticeable as she had more gray. Within a week you could see dark hair peppered all over her scalp. Wheatgrass contains so many nutrients including copper, so it is fantastic to take every day. There is much information on it on the web. I had fantastic blood results by taking wheatgrass.
