The outward appearance has been recognized as an important factor in expressing the image of individual, and there has been a trend towards changing the image through a variety of hair styles. The thermal permanent wave treatment has recently been given much preference. However, the flat iron permanent treatment is accompanied by strong heat treatment and therefore increases the damage to hairs. This study conducted a preliminary investigation into the awareness among the consumers and beauty experts towards the hair damage which results from the flat iron permanent treatment. The results showed that both consumers and beauty experts recognized that the hair flat iron would result in the damage to the hairs. In response to that, an experiment was conducted to derive the appropriate temperature of flat iron permanent treatment. The results indicated that the thickness of hair drastically decreased in black hair group as the heat treatment temperature increased. Specifically, the brightness(L*) increased while the redness (a*) and yellowness (b*) decreased. In addition, the results of measurement with the SEM suggested that the extent of hair damage induced by the heat treatment was higher in the colored hair group than in black hair group. It is considered that the damage to the hairs could be reduced by the heat treatment ofup to 180oC for the black hair group and up to 160oC for the colored hair group, regarding the heat treatment of up to 120oC-200oC.
