In The Outsiders, how do Johnny and Ponyboy disguise themselves?

In "The Outsiders," by S.E. Hinton, the characters of Ponyboy and Johnny were involved in an attack by the Socs.  Johnny stabbed and killed Bob in order to save Ponyboy's life.  They ran to Jay Mountain and hid in an old church.  To disguise themselves they cut and washed their hair.  Ponyboy dyed his blond.  Johnny says he would dye his also but it was so dark the dye wouldn't take.  They tried to hide out and changed as much as they could.  They lost weight because of lack of meals and with the short hair and Ponyboy's dye job they were disguised.
