Is it true that your hair will be different after you have shaved your head?

I was thinking of doing a Chelsea haircut, here’s a picture of what a Chelsea haircut is if you didn’t know what it was http://upload.wikimedia.org/wikipedia/commons/a/a1/Chelseahaircutstephphoto527.JPG

I’ve talked to my mom about it, when she saw that I have to shave my head for that haircut she told me that people have told her that your hair wouldn’t be as nice as it was before you’ve shaven it. So to that meaning they meant for instance, if you had smooth silky wavy hair or so and you shaved your head your hair wouldn’t grow back as nicely, silky and wavy as it was.
Is this true?
