A typical healthy person loses up to 100 hairs per day. This is completely normal and has to do with the lifecycle of hair. When pregnant, the extra hormone levels extend the life of hair. So pregnant women many times have very thick luxurious hair. But once the pregnancy hormones are done, youhave all these hairs that all of a sudden die off. This too is completely normal and is just a catching-up process. There really isnt a way to stop it.
