Actually most of the pregnant women I've talked to have not noticed a reduction in hair loss, but normal or even increased amounts of shedding.
I have definitely fallen into the later category of increased amounts of hair loss probably due to the fact that my body now calls for an increase in protein and since my body can't easily provide it, it takes all the protein intake it gets that would normally have gone to my hair and nails and has redirected it. Which of course is in the best interest of the baby, it just kind of messes with your head when you were expecting one thing and another happens.
Thank goodness I am finally being able to eat meat slowly a little at a time. Chicken for the first time since I got pregnant yesterday. And I was actually craving steak earlier today so this could be more hopeful for my hair situation if I can increase my protein intake.
Maybe someday near the end of my pregnancy I'll see those gorgeous luscious locks people tell you about.
^^^ I used to have hair like that. Hopefully soon again ^^^
