"I was just about to dye my hair with Henna because of a photoshoot, but I'm so glad that I saw these BEFORE I did anything to my hair. These two hairs fell off when I was doing yoga today, and I was SO happy to see that the roots are dark while the ends are grey!! I haven't seen these at all over the months, so this is the first time I saw real dark hair growing out from the grey. The one on the left has about 2 inches of dark hair and the ending is about one centimeter of grey/white (it doesn't show much on the photo but it's there); and the one on the right has mostly grey until the last inch. There seemed to be a short transition when the color got more intense from a light tint, and then it just became completely dark. I'm not sure how long my hair has grown in the last six months since I started the protocol (though it took me MONTHS to get rid of more and more fragrances in my life). My hair usually grows pretty fast (my hair dresser used to tell me) but I don't know how long it takes me to grow 2 inches to 1 inch. So, these two seem to have responded pretty soon after I started the protocol!
