As part of Filipino myth/tradition is to cut the baby's hair when he turns one and keep it in between pages of a dictionary or bible. They say it's going to help the kid be more intelligent. Is anyone still doing it? Does it really work?

Lol, my mother-in-law just did this. I'm non-religious so I'd have just thrown it away but she was there when I trimmed the hair and she collected it. I let her be, it's her happiness. She also did the same with the first cut fingernails. Of course it doesn't work. It's a superstition and has no scientific basis. Your child will be intelligent based on his learning temperament and the teaching environment & lessons you provide. The right education is what really matters.
