I thot that was normal. Lose your baby hair - grow new hair. My mom said i was born w/hair, it fell out, then it didn't really grow back until i was 3
(she thinks that's a funny story
But, maybe it was something bad? Dunno
Oh, wait, lose YOUR hair - yeah, that happened, too. My hair got really thick while pg, and all the extra stuff fell out afterwards. Skin got all soft and luxurious, nails grew, scratches healed very fast (the cat and I box sometimes, he has those pointy things). All the miraculous stuff went away after wards. ah, well.
once I was losing my hair in clumps, but i was due to stress. quit my job, hair grew back. didn't look bald, but i had these whispy bits growing out all over.
