Comment For Authors:
Dear Authors,
Although the authors say that traction alopecia is present at any age, any gender, they chose
only women over the age of 18 for the study. The participation of children and men could
provide ample information on this statement. If children were not asked to participate in this
study because of the difficulty of obtaining the consent of parents or guardians, then what is
the reason for the absence of men. In addition, age was shown in this study as the main factor
in the installation of traction alopecia. Other factors that may be less dangerous if an education
was presented.
