Well, physically, Ponyboy dyes and cuts his hair and Johnny only cuts his hair since his hair is to dark to dye. Not physically, I would have to say they or at least Ponyboy is putting it hard on himself. They are more alarmed. They probably look at things a different way now. That's all i got sorry. :/ I hope this helps. If you have any other questions just ask. Because I loved that book! And i would love to answer more questions for you. As long as you read the book. :)
