My hair changed completely during pregnancy. I've always had fine hair that got stringy & gross if it got longer than an inch or two above my shoulders.

During pregnancy i got more hair, it got more body & it actually grew in length. It was the first time I got to experience long hair. It was great.

Part of it is because you don't lose hair during pregnancy so it gets thicker. Hence the ridiculous shedding post-pregnancy when your hormones return to normal.
