newborn hair

I was wondering if there are any other preemie mommies out there? 
My question is what do you use in your baby's hair? My daughter is a month old and she has a very good grade of hair, but the back of her hair is fallen out from being put on her back in the NICU so just wondering what can I use to grow her hair and keep her texture. 
(Ohh and it was the NICU doctors who told me her being placed on her back all the time is the reason her hair came out)
