some people do notice that their hair can be thicker and fuller when pregnant and this is a hormonal fluctuation. so what happens is that your hair has three cycles of growth: it has a growing phase a resting phase and a falling out phase. sometimes with the hormones and the changes in pregnancy your hair stays in that growing phase longer. so you have more hair in that growing phase so your hair looks thicker and fuller and grows longer and often is more shiny as well. what happens though is three to four months after pregnancy when those cycle shift back all of a sudden that hair starts to shed as you revert back to your normal hair cycles. so if all your hair grew in the growing phase at the same time and then shifted to the resting phase every two to ten years or so you would go bald completely. but fortunately that pattern is not synchronized. so about 90% of your hair is growing and 10% is resting or falling out. so if that patterns shifts you might notice that your hair looks fuller for a while but there is a price to pay on the other side and then it will balance back out. yes mine did. and then after i had my baby girl i lost quite a bit of it <positive_smiley>
