Abstract |
Abstract This study comparatively analyzed hair bleaching and degree of damage by
the temperature of a heating tool after coloring hair with a permanent, semi-permanent
or plant hair dye. According to analysis by spectrophotometer, ¡®semi-permanent hair dye¡¯
was the highest, followed by ¡®permanent hair dye¡¯ and ¡®plant hair dye¡¯ in terms of changes
in L* values. In terms of changes in hair shape when analyzed using FE-SEM, ¡®semi-permanent
hair dye(150¢ªC or lower)¡¯ was the greatest, followed by ¡®plant hair dye(180¢ªC or
lower)¡¯ and ¡®permanent hair dye(200¢ªC or lower)¡¯. Therefore, it is reasonable to flat iron
hair at low temperature. According to the test, amino acid values gradually decreased in
both bleached and colored hair. The results obtained through TGA-based thermal analysis
confirmed that as brightness increases, hair moisture contents decrease. This study aimed
to protect hair by suggesting a correct use of a flat iron by the hair dye type during hair
coloring. It appears that the study results would help hairdressers minimize hair damage
by using a hair dye at proper temperature. |
