For the pro-tec piece you could use doll hair from a craft store or artificial fur from a fabric shop. This can be attached using archery glue: NPV, HMG, Duco, Goat tuff and other brands that are used to glue the vanes, feathers, or nocks to the shaft. Of course you could use epoxy or even a hot melt glue but the archery glue can be applied in a thin bead and avoid the lumps that a glue gun causes and the hair clumping that epoxy glues tend to cause.
To attach the pro-tec piece back to the head, you can use a good epoxy-type cement or Goop.
