Henna(Lawsonia intermis) 염색이 모발의 색도변화와 큐티클 형태 변화에 미치는 영향 = A Study on Color Change and Cuticle Change by Henna Dyeing on Hair

다국어 초록 (Multilingual Abstract)

Continuous using of blaching agents and oxidative hair dyeing agents induced to damage of hair cuticle and cortex layer. In this study, color change and morphological change of cuticle were observed by henna (Lawsonia innermis) dyeing on hair. Prepared 5 hair pieces without normal hair piece were delcolored, acid colorant treated or henna treated, and observed lightness, redness and yellowness by measurement of chromo meter and morphological change of cuticle by observation of SEM. In the result, the diameter of bleached hair (6% hydrogen peoxide treated) was significantly thinner than normal hair, acid colorant incubated and henna incubated hairs(p<0.005), and normal and 1/3 hrs henna incubated hairs were 12 μm. The highest lightness was showed bleached hair and henna treated hairs were showed the highest redness and yellowness. Lightness, redness and yellowness is not dependent on reaction time by using of acid colorant and henna. Cuticle damage and microfilament bundle were revealed on bleached hair. Henna treated hairs were showed weak cuticle damage and no exposure of microfilament. And hair damage on acid colorant treated hairs was stronger than henna treated hairs. In conclusion, henna could be protect of cuticle and may be very good natural dye for hair coloring.
