In areas where healthcare facilities no longer required their nurses to wear nurse's caps, nursing schools eliminated the cap as a mandatory part of the students’ uniform. In addition, with the growth of technology in the health-care setting, some felt that the nurse's caps were an obstacle for nurses wearing them, while others disagreed. Also, with the rapid growth of the number of men in nursing, some felt a need for a unisex uniform, while others saw no difficulty with gender specific uniforms as is the case in many uniformed professions. However, nurses' caps can still be found in many developing and developed nations. Japan and South Korea are examples of developed countries with near universal use of the nurses' cap. It is also common for students of nursing to have their graduation portraits taken while wearing nurses' caps.
