Experience cutting your infant's hair?

We cut my daughter's hair when she was 2 and it still feels just the same as it did. My parents used to cut my hair and shave it alot when I was a baby in the hopes it would grow faster, by the age of 4 I still had barely any hair, but till this day my hair is still soft as anything and feels silky, that was 26 years ago. I think it all comes down to genes, if its in their genes to have course hair, it will happen over time no matter what, if they are going to have silky thin hair its going to happen, no amount of cutting or shaving will effect it.
