Look closely at the pieces you do have and you should be able to identify the pieces that are from the head. Unless it is hypo you should be able to recognize the pattern as well as the scale shapes. Once you find those, look for the eye caps. If they are there then it is just that the bad humidity has left the new eye caps wrinkled. If they are not there then you know they are stuck. Either way you need to bump up and maintain proper humidity and it will improve with the next shed. Good luck
