If you find a solution to hair shedding let me know. I shed hair all the time. My hair is down to my tailbone, so even a small number of hairs looks like I've lost a whole scalp full.
Many people lose hair early on with this diet because new growth is stimulated. This pushes out hairs that were laying there dormant but still attached. It's not all about carbs or supplements.
My own hair shedding is a constant occurence made more noticable simply by having much longer hair than I used to.
