Abstract

Morphological and physicochemical changes of a woman's virgin hair treated with various dye depths were investigated by using scanning electron microscopy and thermal analyzer. With the hair treated with the dye of the high brightness level, the speed of weight decrease was slower than compared with thermal analysis weight of a normal hair sample. We confirmed that the moisture content and protein composition of hair were changed depending on level depth of coloring agent. Moreover oxidative residues and dye molecules penetrated into the hair cause chemical changes of hair structure. As a result, the heat reaction speed of hair treated with high level coloring agent was made slower than normal hair.

본 연구는 색상을 함유하고 있지 않은 자연계열의 염모제인 9/00과 14/00을 여성의 건강모발에 염색한 후 염색된 모발을 열분석과 주사전자현미경을 이용하여 모발의 물리 화학적인 변화를 규명하였다. 열분석에서 정상 모발시료의 경우 열에 대한 연소 반응이 비교적 빠르게 나타났으며, 9/00 염색모발의 경우에는 건강모발과 14/00염색 모발의 중간 정도의 연소반응을 나타냈고, 14/00 염색 모발의 경우에는 열에 대한 연소반응이 비교적 느리게 나타나는 것을 확인하였다. 이는 고명도의 염모제일수록 모발의 수분 함유량이 감소되었다는 것을 의미하며, 모발 내부로 침투한 산화물과 염료 분자로 인하여 모발의 화학적 변화가 야기된 것으로 사료된다.
