Abstract

Variations of the seventeen amino acids(aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, cystein, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, histidine, lysine, arginine) were analyzed in human hair sample by amino acid auto analyzer(AAA). The effect of bleaching and permanent wave manipulation on the amino acid composition of hair were investigated. Hair samples were collected from 10 males in their thirties. Hair samples were treated with 10 mL of 6 N hydrochloric acid at $110^{\circ}C$ for 24 h and analysed by AAA. The results showed that the amino acid content of normal hair(73.9%) decreased to 71.5% and 69.3% after bleaching and permanent wave treatment, respectively. Furthermore, mean contents of lysine and tyrosine in amino acids showed obviously decreased about 25% by permanent wave and bleaching treatment. On the other hand, serine, cystein, leucine and histidine were not changed.

아미노산 자동분석기(amino acid auto analyzer, AAA)를 이용하여 모발의 탈색 및 퍼머넌트 웨이브 시술에 의한 모발시료의 17가지 아미노산(aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, cystein, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, histidine, lysine, arginine) 함량변화를 조사하였다. 시료는 30대 남성 10명의 모발을 채취하였으며 $110^{\circ}C$ 24 h 동안 6 N 염산 10 mL로 가수분해 후 분석하였다. 실험결과 처치별 모발의 아미노산 함량은 정상모발 73.9%, 퍼머넌트 웨이브 모발 71.5% 및 탈색모발 69.3%로 분석되었고, 탈색효과에 의한 아미노산 함량 감소가 퍼머넌트 웨이브 효과에서 보다 크게 분석되었다. 특히 lysine과 tyrosine의 조성은 탈색이나 퍼머넌트 웨이브 모발에서 25% 가량 현저히 감소하였다. 반면에 serine, cystein, leucine 및 histidine의 함량변화는 일어나지 않았다.
