Does shaving baby's hair really make their hair grow more n longer eventually?

You should wait your baby to shave or cut the hair when he was 1 year old or over. When I have my youngest son, his hair was to thin. When he was 2-3 years old I started to shave his hair to make it thicker. I shaved his hair every 2-3 weeks and I saw the difference. It get thicker and thicker and it grows fast. Until now, I still shaving his hair every 2 weeks. He was already 5 years old. He also looks very cute and neat of that kind of haircut.
