My son has baby-soft curly hair when he was younger. It got quite long because we loved the curls so much. We finally decided to get his hair cut and his hair it straight now. I'm pretty sure the actual cutting of the hair doesn't change anything, it's just that as they get older their hair can change anyway. DS's hair is much thicker and more child-like (rather than baby-like) now, so I'm sure it would have lost the curls in the new growth anyway. I do love looking back through his photos though at his silky curls
