Christina, cheer up.. actually cutting bald for baby will let their hair grow faster n nicer when they grow up. My girl is botak when she reaches one month too. Now her hair is growing back n much blacker compared to previous looks. It kind of traditional way that chinese do.
Ya, everyday after bathing her, you can apply some olive oil on to her head. It also helps hair to grow faster
P.s. tell your hubby.. is not that the hair is dirty.. newborn's hair shld be kept with the stomach thing in a ang pao - belongs to your girl.
