Both the number and percentage of actual harvested 1\u2010hair follicular unit were more than estimated 1\u2010hair follicular unit. In contrast, the number and percentage of actual harvested 3\u2010hair follicular unit was less than estimated 3\u2010hair follicular unit. The follicular unit density was lower in older patients. Those received more than one session of hair transplantation tended to have lower follicular and hair density (<jats:italic>P\u00a0<\/jats:italic>=\u00a00.007 and 0.01, respectively).
