Great to hear the success stories! I can tell that my hair is growing better/faster, and that of my nearly 3 year old son, too. We've been primal a few months now, maybe 2.5-3, with slightly more than 20% of "cheats" in our diet due to our church providing meals 3 times a week during a couple of months of bedrest and now 3 weeks postpartum (and many don't "get" our lifestyle, so just getting them to cut the wheat has been difficult).
Anyway, the toddler's hair was very dry and coarse, not growing quickly. It is now thick, soft, and growing much more quickly. It is gorgeous and feels healthy. (He has also gained 5 pounds and about 3 inches of height in the last month, thickening out & looking healthier in general).
As for me, I'm already starting the postpartum hair loss. But as I see that, I also see that there are tons of little hairs underneath, and my hair feels thicker & healthier, even with the postpartum hair loss starting. My hair is growing faster, and I find that I actually need to shave my arms about twice a week (usually I could go every 10 days!), and if it were still shorts weather, I'd be doing my legs as frequently too. It will be interesting to see the color of the hair, as well as texture, as it grows in better.
