본 연구는 펌 시술시 1제와 2제의 잔류 문제점들을 중간세척제로 전해수를 사용하여 알칼리성분 제거 하였고, 이황화결합을 더욱 가속화 시켜 웨이브가 잘 나올 가능성을 가지고 산업현장에 적용하는 목적을 두고 있다.
따라서 본 연구에서는 자연모, 펌모, 탈색모 모발 시료를 가지고 1제로 환원모를 만든 후 중간세척 과정에서 전해수를 사용하고 2제를 처리하여 웨이브의 형성력과 지속력 모발의 굵기, MB 염색법에 의한 모발의 밀도, 인장강도, 전계방출 주사전자현미경을 통한 모발표면을 관찰하여, 중간세척제로 전해수를 사용할 수 있는지 그 가능성을 검토한 것이다. 펌 과정 중 1제로 환원모를 만들고 40℃, 47℃, 52℃로 가온처리 한 후, 중간세척 없이 2제를 처리한 대조군(C1), 중간세척제로 수돗물(C2), 산성전해수(E1), 염기성전해수(E2)를 사용하였으며, E3은 중간세척제는 E2와 같으나 2제 처리 후 다시 산성전해수를 후처리제로 사용한 경우이다.
첫 번째, 자연모발의 결과이다. 웨이브 형성력과 지속력은 52℃ > 47℃ > 40℃ 순으로 온도가 높을수록 좋았고, 47℃, 52℃에서 모두 E3 > E2 > E1 > C2 > C1 순으로 좋았다. 모발 굵기, 인장강도, methylene bule법으로 추정한 모발밀도는 40℃ > 47℃ > 52℃ 순으로 좋아 웨이브 형성력, 지속력과 반대였다. 그리고 47℃와 52℃에서 모발의 굵기는 E3 > E2 > C1 ≒ E1 > C2 순이었으며, 인장강도와 methylene bule법으로 추정한 모발밀도는 E3 > C1 > E1 > E2 > C2 순이었다. Field-emission scanning electron microscope(전계방출 주사현미경)로 관찰 결과 52℃의 모발 시료들의 큐티클이 가장 안정된 순서는 E3 > E1 ≒ C1 > E2 > C2 순이었다.

Field-emission scanning electron microscope로 관찰 결과 52℃의 모발 시료들의 큐티클이 가장 안정된 순서는 E3 > E1 > C1 > E2 > C2 순이었다.
따라서 E3가 모든 측정항목에서 가장 좋았으며, E1, E2도 웨이브 형성력과 지속력이 좋아 중간세척제로 전해수 사용이 가능한 것을 알 수 있었으며, 특히 E3 방법은 펌 시술 시 인체에 안전한 전해수 사용이 뷰티산업에 적용해야할 매우 중요한 결과로 보인다.

The purpose of this study is to see if the electrolyzed water can be used as the intermediate cleaner to eliminate residue problems of the primary and secondary solutions by eliminating alkaline components. The method is intended to accelerate disulfide bonds, which may enhance the quality of the curl waves in the industry practice.
As such, the current study utilizes natural, curled, and bleached hair samples to make deoxidized hair with primary solution, and then use electrolyzed water to rinse. Finally, treatment with secondary solution is conducted. Finished hair samples are tested for curl formative power and sustainability, hair thickness, hair density using methylene blue (MB) staining, tensile strength and the surface of hairs by using field emission scanning electron microscopy (FE-SEM).
In this study, we used electrolyzed water as the intermediate cleaner and treated hairs with no. 2 agent after hairs were reduced by using no. 1 agent during the perm treatment on the sample hair (natural hairs, permed hairs, bleached hairs). After hairs were heated at various temperatures such as 40℃, 47℃ and 52℃, groups were treated with no. 2 agent and a variety of water as the intermediate cleaner as follows: control group (C1) using no intermediate cleaner, C2 using tap water, E1 using acidic electrolyzed water, E2 using basic electrolyzed water and E3 using acidic electrolyzed water after it was treated with basic electrolyzed water.
First, the results of natural hairs are as follows. Curl formative power and sustainability were better as hairs were heated at higher temperature in the following order: 52℃ > 47℃ > 40℃. Curl formative power and sustainability at 47℃ and 52℃ were higher in the following order of groups: E3 > E2 > E1 > C2 > C1. Hair thickness, tensile strength and hair density estimated by using methylene blue staining were higher in the following order: 40℃ > 47℃ > 52℃. The order was opposite to that of curl formative power and sustainability. In addition, hair thickness at 47℃ and 52℃ was higher in the following order of groups: E3 > E2 > C1 ≒ E1 > C2. Tensile strength and hair density estimated by using methylene blue staining were higher in the following order of groups: E3 > C1 > E1 > E2 > C2. According to observation using FE-SEM, cuticles of hair samples at 52℃ were more stable in the following order of groups: E3 > E1 ≒ C1 > E2 > C2. Therefore, E3 showed the highest values in all measuring items.
Second, the results of permed hairs are as follows. Curl formative power and sustainability were better as hairs were heated at higher temperature in the following order: 52℃ > 47℃ > 40℃. Curl formative power and sustainability at 47℃ and 52℃ were higher in the following order of groups: E3 > E2 > E1 > C2 > C1. Hair thickness, tensile strength and hair density estimated by using methylene blue staining were higher in the following order: 40℃ > 47℃ > 52℃. The order was opposite to that of curl formative power and sustainability. In addition, hair thickness at 47℃ and 52℃ was higher in the following order of groups: E3 > E2 > C1 > E1 > C2. Tensile strength and hair density estimated by using methylene blue staining were higher in the following order of groups: E3 > C1 > E1 > E2 > C2. According to
observation using FE-SEM, cuticles of hair samples at 52℃ were more stable in the following order of groups: E3 > E1 > C1 > E2 > C2. Therefore, E3 showed the highest values in all measuring items.
Finally, the results of bleached hairs are as follows. Curl formative power and sustainability were better as hairs were heated at higher temperature in the following order: 52℃ > 47℃ > 40℃. Curl formative power and sustainability at 47℃ and 52℃ were higher in the following order of groups: E3 > E2 > E1 > C2 > C1. Hair thickness, tensile strength and hair density estimated by using methylene blue staining were higher in the following order: 40℃ > 47℃ > 52℃. The order was opposite to that of curl formative power and sustainability. In addition, hair thickness at 47℃ and 52℃ was higher in the following order of groups: E3 > E2 > C1 > E1 > C2. Tensile strength and hair density estimated by using methylene blue staining were higher in the following order of groups: E3 > C1 > E1 > E2 > C2. According to observation using FE-SEM, cuticles of hair samples at 52℃ were more stable in the following order of groups: E3 > E1 > C1 > E2 > C2. Therefore, E3 showed the highest values in all measuring items.
As E1 and E2 showed high curl formative power and sustainability, the electrolyzed water can be used as the intermediate cleaner. In particular, E3 seems to have very important results to be applied in the field.
