I agree with posting your menu this week, there's a number of possible reasons for hair loss. Clumps? Well, I'm not sure about that one. Not enough calories, vitamins, and nutriets can effect hair loss, as well as extreme stress and hormones. I know that when I'm extremely stressed, Low carb or not, I lose hair---it's like a cat has shed around the house and stopped up the drain. No, we don't own a cat. However, the hair that is replaced (and the stress level goes down), I have a nice shiny coat (hair) when I'm solid on this way of eating--my nails don't look half bad either! Check you vitamins, what you're eating (enough fat, calories, and nutrients), and drink your water too.
