Shave or not to shave???

Xavier got a few bald patches from lying on his back too much
Thought of shaving his hair... so that can grow more evenly
Currently, he has nice beckham hairstyle which I couldn't bear to shave off. I'm afraid that once I shave it off, it will not be as nice as what he's having now.

HOW.... Shave or not to shave?????

Is it true that shaving a baby's head (or cutting his hair very short) makes the hair grow in thicker and stronger?

If yes, I will do it!!!!!
