I am on a Nutritional balancing protocol for almost a year now. I was 27, when I first saw a few grey hair and then by the time I was 44 my head was about 40% grey and my roots also became very dark, almost like a witches hair, black and grey. When I was about 6 months into the protocol I have noticed much less grey, and I mentioned this to my Practitioner and she stated that I am absorbing much more of the calcium then prior..My 1 st hair analysis showed off the charts calcium, which was over 120..now I am in the range of 40 and my grey hair is about 10 % of my head and the black roots are not as dark.
