복합시술 모발의 자외선 보호처리에 따른 손상도와 색상 변화 = Change of Hair Damage Degree and Hue in Complex-treated Hair according to UV-protection Care

다국어 초록 (Multilingual Abstract)

This study aimed to determine the effects of UV-blocking by the type of UV care agent for complex-treated hair. For this, healthy women’s hair was permed, bleached and dyed, and a Polypeptide Protein Treatment and hair sunscreen agent were applied. After that, changes in the degree of wave formation, hair surface conditions, physical properties of the hair and hair hue were examined by irradiating UVB rays. The analysis results were found as follows: In terms of the degree of wave formation, no difference was observed among UV care agents. In terms of hair surface scale, hair damage was lower when the hair was coated twice as opposed to being coated once regardless of the type of the UV care agent and treatment method. In addition, tensile strength, elongation rate and resilience rate were superior in the hair recoated with the hair sunscreen agent. In contrast, no significant difference was observed among the UV care agents in terms of damage rates. Lightness and reflected light were also high in the hair recoated with the hair sunscreen agent. In addition, the a* value, reflection and dominant wavelength were the highest in the hair with post-treatment coating for the skin while b* value, reflection and degree of irritation was the highest in the hair with post-treatment coating for hair. The said results can be summarized as follows: The UV care agent revealed effective UV-blocking effects by maintaining the wave formation and preventing hair damage. When UV rays were irradiated, the hair for post-treatment product was the most efficient in maintaining hair color.
