Hi D.,
I think it has something to do with your diet. When I was pregnant with my second baby my skin was so horribly dark and dry looking. I knew it was because of the baby, he was depleting me of one the supplement which supports healthy skin. Maybe that's what's going on with you, the baby has depleted you of that supplement which helps your hair growth and health.
I suggest you get some vitamin supplements that help with the growth in hair and nails. Also, how are your nails doing...if they are also not healthy than that confirms my notion. I'm not a doctor but I am 42 and have experienced a lot. You can find healthy supplements and great customer support at Whole Foods, GNC or Trader Joes.
PS. Pink is the new cool for all genders. :)
good luck.
