Interestingly, my hair seems to be changing color. I think I was severely malnourished from lack of HCL for several years without realizing it and wondered if this was why my hair went gray so fast, among other things. Now it appears to be growing in light brown or dark blonde after a couple of months of primal eating. I'm in a bit of disbelief at the moment and keep thinking I'm imagining things. My hair used to be medium brown with red highlights. Hmmm, what to do? I recently started coloring with henna and indigo so not sure what to do until this grows out.
