Thioglycolic acid와 열 펌에 의해 손상된 모발에 관한 연구 = Regular Articles : Study on the Damaged Hair by Thioglycolic Acid and Heat Source

다국어 초록 (Multilingual Abstract)

We investigated the morphological and physical characteristics of the permanent waving hair treatment with thioglicolic acid, heat for 10 minutes and 20 minutes respectively, using scanning electron microscopy and absorbancy. To find the effective method to cure the damage which hurt by the permanent wave, cold-permanent and heat-permanent wave are conducted by use material mainly include thioglycolic acid. The hair damage by thioglycolic acid and heat-permanent are investigated with using absorbancy. In absorbance test, values of treated cold permanent hair group are higher than heat permanent hair groups, because of swelling by reducing agent, treatments and matrix adsorption with methylene blue. It seems to have a high absorbance because of change of the chemical bond of cell membrane complex in the hair. In the scanning electron microscopy, The surface of hair after treatment with thioglicolic acid was observed to split and damage of scale. The scale on the cuticular Layer of hair began to be separated. The scale of permanent hair surface with heat for 10 minutes was lifted off and some cytoplasm of cuticular cells was broken into pieces. In the permanent hair treatment with heat for 20 minutes. the surface of cuticle was fissured and lifted off. The cell debris attached on the surface of cuticular cell membrane.
