He was the only boy on the island whose hair never seemed to grow

This quote is talking about how the other children are changing and how Piggy is staying tied to his values.  The hair is a symbol of how "wild" the kids have become.  Piggies hair has not grown very much at all, suggesting that he has stayed to his morals and has not changed.  Golding wanted to serve this as a metaphor for life, stick to your guns and dont change your views just because the people around you are doing a ceartain thing.

"He was the only boy on the island whose hair never seemed to grow."

This quote is talking about piggy.  I think the hair represents how the boys have changed from their city school going selves to wild boys who hunt their food and build fires for rescue.  Jack hunts the most and his hair is the longest, Piggy has not really changed his views throughout the book.  Golding is trying to show that unlike everyone else Piggy is keeping to what he thinks is right.  I think Golding is using Piggy as a life lesson, don't let your surroundings change your beliefs and morals.
