I noticed this when I went low-carb for awhile. Make sure you are getting adequate carb intake, in addition to the other nutrients (especially the Ss – salty, sweet, starchy, saturated fat). I have also heard people say that your hair will fall out to an extent, as new hair replaces it. I never noticed this myself, because as soon as I upped the carbs A LOT my hair returned basically to normal.
Hope that helps.
