도 1은 본 발명의 일 실시예에 따른 모발 진단 시스템을 개략적으로 나타낸 블록도에 관한 것으로서, 도 1을 참조하면, 본 발명의 일 실시예에 따른 모발 진단 시스템은, 레이저 광원과 검출 핀홀 상의 초점을 일치시키고, 모발을 초점면 상에 배치하여 모발을 통과하거나 반사되는 빛을 통하여 상기 모발의 영상을 촬영하는 모발 촬영부(10), 촬영된 모발의 영상에서, 상기 빛이 반사되는 제1 영역과 빛이 반사되지 않는 제2 영역으로 나누는 영상 처리부(20), 및 상기 제1 영역의 면적을 통하여 모발의 광택도를 산출하는 광택도 산출부(30)를 포함한다.1 is a block diagram schematically illustrating a hair diagnosis system according to an embodiment of the present invention. Referring to FIG. 1, a hair diagnosis system according to an embodiment of the present invention is a focal point on a laser light source and a detection pinhole. To match the hair, and the hair is placed on the focal plane to shoot the image of the hair through the light passing through or reflected from the hair photographing unit 10, in the image of the photographed hair, the first region where the light is reflected And an image processor 20 dividing the light into a second region in which light is not reflected, and a glossiness calculator 30 to calculate the glossiness of the hair through the area of the first region.
상기 모발 촬영부(10)는 레이저를 광원으로 하여 포인트 소스에서 나오는 광을 사용하여 시료의 초점과 검출 핀홀(pinhole)의 상의 초점을 일치시켜 초점면 이외의 부분은 영상에서 나타나지 않게 하여 시료를 측정하도록 형성된다. 본 발명의 일 실시예에 따르면, 상기 모발 촬영부(10)로 공초점 레이저 주사 현미경(CLSM; Laser scanning confocal microscopy)이 사용될 수 있다.The hair imaging unit 10 measures the sample by matching the focus of the sample with the focus of the detection pinhole using light emitted from a point source using a laser as a light source so that portions other than the focal plane do not appear in the image. It is formed to. According to one embodiment of the present invention, a laser scanning confocal microscopy (CLSM) may be used as the hair imaging unit 10.
상기 모발 촬영부(10)는 공초점 레이저 주사 현미경을 사용하여 위와 같은 방식으로 모발(시료)을 측정하기 때문에 기존 형광 현미경보다 해상도가 1.4배 정도 높다. 또한, 광축에 핀홀을 설치하여 모발을 통과하거나 시료에서 반사되는 광선을 선택할 수 있으며, 초점이 맞지 않으면 핀홀을 통과하지 않게 하여 해상력을 극대화할 수 있다. 그에 따라, 모발 1가닥에서의 미세한 반사광의 변화도 측정할 수 있다.The hair imaging unit 10 measures the hair (sample) in the same manner as above using a confocal laser scanning microscope, and thus resolution is about 1.4 times higher than that of a conventional fluorescence microscope. In addition, by installing a pinhole in the optical axis can select the light beam passing through the hair or reflected from the sample, and if the focus is not in focus, it does not pass through the pinhole to maximize the resolution. Thereby, the change of the minute reflected light in 1 hair strand can also be measured.
또한, 모발의 내부까지 단층으로 스캐닝하여 내부 구조를 시각화할 수 있고, 2차원 영상은 컴퓨터 소프트웨어 프로그램을 통하여 3차원 입체 영상으로 재구축 할 수 있다. 그에 따라, 일반 광학 현미경에서 관찰할 수 없었던 단면의 이미지도 관찰할 수 있으며, 부피가 있는 구조물의 경우 현미경을 통하여 원하는 방향의 영상을 얻을 수 있다.In addition, the internal structure can be visualized by scanning a single layer to the inside of the hair, and the 2D image can be reconstructed into a 3D stereoscopic image through a computer software program. Accordingly, it is possible to observe an image of the cross section which cannot be observed in a general optical microscope, and in the case of a bulky structure, an image of a desired direction can be obtained through a microscope.
따라서, 본 발명의 일 실시예에 따르면 상기 모발 촬영부(10)를 통하여 모발의 단면 곡선, 거칠기 곡선, 파장곡선 및 표면 영역 등의 물리적인 특성을 수치화하여 분석할 수 있다.Therefore, according to an embodiment of the present invention, the physical properties such as cross-sectional curves, roughness curves, wavelength curves, and surface areas of the hair may be numerically analyzed through the hair photographing unit 10.
상기 모발 촬영부(10)는 1가닥의 모발을 통하여 모발 영상을 획득할 수 있다. 그에 따라 피험자가 직접 촬영 장치까지 가지 않아도, 1가닥의 모발만 있으면 모발의 광택도를 측정할 수 있다. 물론, 하나 이상의 모발에 대하여도 모발 영상 측정을 통한 광택도의 분석이 가능하다.The hair imaging unit 10 may obtain a hair image through one strand of hair. Therefore, even if a subject does not go to a photographing apparatus directly, only one strand of hair can measure the glossiness of hair. Of course, it is possible to analyze the glossiness by measuring the hair image even for one or more hairs.
본 명세서에서, "광택도"라는 용어는 모발에서 단위 면적당 또는 모발의 기 설정된 영역에서 빛을 반사시키는 정도를 나타내는 것이다. 보다 구체적으로, 테스트하고자 하는 모발에서 소정의 광원에 대하여 어느 정도의 빛을 반사시킬 수 있느냐를 의미하는 것으로, 반사시키는 빛의 양이 많아질수록 모발이 윤기가 있어 보이므로, 모발의 윤기 또는 광택을 평가하는 척도가 될 수 있다.As used herein, the term "glossiness" refers to the degree of reflection of light per unit area in the hair or in a predetermined area of the hair. More specifically, it means how much light can be reflected to a predetermined light source in the hair to be tested, and as the amount of reflected light increases, the hair looks glossy, so that the hair is shiny or glossy Can be a measure of
상기 모발 촬영부(10)는 모발에서 모근으로부터 기 설정된 위치의 모발 영상을 촬영할 수 있다. 정확한 비교 및 분석을 위하여, 모발의 모근으로부터 기 설정된 위치의 모발 영상을 촬영하여 분석할 수 있다.The hair photographing unit 10 may capture a hair image of a predetermined position from the hair root in the hair. For accurate comparison and analysis, a hair image of a predetermined position may be taken and analyzed from the hair root of the hair.
구체적으로, 모발 촬영부(10)는 모발 노화를 측정하기 위하여 모근으로부터 기 설정된 위치, 일 예로 모근에서 대략 3 ~ 5 cm의 위치에서 모발 영상을 측정할 수 있다. 모근에 가까운 모발일수록 다른 환경 요인에 의한 영향이 적기 때문이다.In detail, the hair imaging unit 10 may measure a hair image at a predetermined position from the hair root, for example, about 3 to 5 cm from the hair root in order to measure hair aging. This is because the hair closer to the hair root is less affected by other environmental factors.
또한, 생활 습관에 의한 모발 관리에 의한 모발 광택도를 측정하기 위하여, 모근의 반대방향 단부에서 기 설정된 위치, 일 예로 모근 반대방향 단부에서 대략 5 ~ 7cm의 위치에서 모발 영상을 측정할 수 있다. 모발의 끝 부분의 상태는 외부 환경에 의한 영향이 큰 부분이기 때문이다.In addition, in order to measure hair glossiness by hair care according to a lifestyle, the hair image may be measured at a predetermined position at an opposite end of the hair root, for example, at a position of approximately 5 to 7 cm at an opposite end of the hair root. This is because the condition of the end of the hair is a part which is greatly influenced by the external environment.
상기 영상 처리부(20)는 촬영된 모발 영상에서, 상기 빛이 반사되는 제1 영역과 빛이 반사되지 않는 제2 영역으로 나눈다. 도 3은 본 발명의 일 실시예에 따라 모발 촬영부(10)에 의해 측정된 모발 영상(a)과 영상 처리부(20)에 의해 제1 영역과 제2 영역으로 구분된 모발 영상(b)을 나타내는 것이다.The image processing unit 20 divides the photographed hair image into a first region where the light is reflected and a second region where the light is not reflected. 3 illustrates a hair image (a) measured by the hair imaging unit 10 and a hair image (b) divided into a first region and a second region by the image processor 20 according to an embodiment of the present invention. To indicate.
상기 영상 처리부(20)에 의하여 제1 영역과 제2 영역으로 구분된 픽셀 이미지를 산출할 수 있다. 그에 따라, 이후 픽셀 값의 합의 계산을 통하여 반사광에 의한 영역의 면적을 계산할 수 있다.The image processor 20 may calculate a pixel image divided into a first area and a second area. Accordingly, the area of the area due to the reflected light can be calculated through the calculation of the sum of the pixel values.
상기 영상 처리부(20)는 본 발명의 일 실시예에 따르면 이미지 변환 프로그램으로 구현될 수 있으며, 반드시 이에 제한되는 것은 아니나 이미지 프로(Image-Pro), 포토샵 등으로 구현될 수 있다.The image processor 20 may be implemented as an image conversion program according to an embodiment of the present invention, but is not necessarily limited thereto, and may be implemented as an image pro or an image.
도 3의 (a)를 참조하면, 모발 촬영부(10)에 의해 측정된 모발 영상은 모발 1가닥에 대한 투과광 또는 반사광에 대한 이미지이다. 도 3의 (b)를 참조하면, 상기 영상 처리부(20)는 반사광만을 따로 분리하여 광택도를 산출하기 위하여, 반사광에 의한 제1 영역과 나머지의 제2 영역, 즉 모발 영상에서 제1 영역을 제외한 제2 영역으로 구별할 수 있다. 상기 제1 영역과 제2 영역은 서로 다른 색상으로 구분될 수 있다. 도 3의 (b)의 경우 제1 영역은 검은색으로 제2 영역은 흰색으로 구별되었으나 반드시 이에 제한되는 것은 아니다.Referring to FIG. 3A, the hair image measured by the hair photographing unit 10 is an image of transmitted light or reflected light with respect to one strand of hair. Referring to FIG. 3B, the image processing unit 20 separates the first region by the reflected light and the remaining second region, that is, the first region from the hair image, in order to calculate the glossiness by separating only the reflected light separately. It can be distinguished by the excluded second area. The first area and the second area may be distinguished by different colors. In the case of FIG. 3B, the first region is black and the second region is white, but is not necessarily limited thereto.
그리고, 상기 광택도 산출부(30)에서 상기 제1 영역의 면적을 산출함으로써, 모발의 광택도를 산출할 수 있다. 보다 구체적으로, 상기 광택도 산출부(30)는, 일 예로 기설정된 위치의, 또는 모발의 단위 길이에 대한, 상기 제1 영역의 면적을 도출하고, 이를 모발의 두께(d)로 나눔으로써 광택도를 산출할 수 있다. 보다 구체적으로, 상기 제1 영역의 면적을 픽셀 값을 합하여 구하고, 모발의 두께(d)로 나누어 광택도를 정량적으로 산출할 수 있다.The glossiness of the hair may be calculated by calculating the area of the first region in the glossiness calculator 30. More specifically, the glossiness calculator 30 derives the area of the first region at a predetermined position or with respect to the unit length of the hair, and divides it by the thickness d of the hair, for example. The degree can be calculated. More specifically, the area of the first region may be obtained by summing pixel values, and the gloss may be quantitatively calculated by dividing by the thickness d of the hair.
모발에서 모발의 두께가 클수록 상기 제1 영역의 면적이 커질 수 있으므로, 정확한 분석을 위하여 모발의 두께 값으로 나누어 단위 두께당 제1 영역의 면적의 비를 구하여 광택도를 산출하여 비교할 수 있다.Since the area of the first region may be larger as the thickness of the hair in the hair increases, the ratio of the area of the first region per unit thickness may be calculated by comparing the thickness of the hair for accurate analysis, and the gloss may be calculated and compared.
본 발명의 일 실시예에 따르면, 공초점 레이저 주사 현미경과 같은 모발 촬영부(10)를 사용하여, 레이저에 의해 모발에서 반사되는 부분의 면적을 이미지 변환을 통하여 정량화하여 광택도를 도출하므로 정확하고, 반복성 있는 결과를 도출할 수 있다. 또한, 공초점 레이저 주사 현미경의 경우 초점이 일치하는 광원의 빛만 통과시킴으로써 원하는 대역의 파장의 광원만 통과시켜 분석할 수 있으므로, 색상이 다르더라도 원하는 대역의 파장의 반사광의 분석이 가능하므로 다양한 머리 색에 대하여도 정확하고, 신뢰도 높은 결과를 도출할 수 있다.According to an embodiment of the present invention, using the hair imaging unit 10, such as a confocal laser scanning microscope, the area of the portion reflected from the hair by the laser is quantified through image conversion to derive the glossiness The result is a repeatable result. In addition, in the case of a confocal laser scanning microscope, only the light of the light source having the same focus can be passed to analyze it by passing only the light source having the wavelength of the desired band. It is also possible to obtain accurate and reliable results for.
도 2는 본 발명의 다른 실시예에 따른 모발 광택 진단 방법에 관한 순서도이다. 본 발명의 모발 광택 진단 방법은, 상술한 모발 광택 진단 시스템을 적용하여 수행될 수 있으며, 상술한 모발 광택 진단 시스템에 대한 설명이 모발 광택 진단 방법에도 적용될 수 있다.2 is a flowchart illustrating a method of diagnosing hair gloss according to another embodiment of the present invention. The hair gloss diagnosis method of the present invention may be performed by applying the hair gloss diagnosis system described above, and the description of the hair gloss diagnosis system described above may also be applied to the hair gloss diagnosis method.
도 2를 참조하면, 본 발명의 일 실시예에 따른 모발 광택 진단 방법은, 레이저 광원과 검출 핀홀 상의 초점을 일치시키고, 모발을 초점면 상에 배치하여 모발에서 반사되는 빛을 통하여 상기 모발의 영상을 촬영하는 모발 촬영 단계(S10), 촬영된 모발의 영상에서, 상기 빛이 반사되는 제1 영역과 빛이 반사되지 않는 제2 영역으로 나누는 영상 처리 단계(S20), 및 상기 제1 영역의 면적을 통하여 모발의 광택도를 산출하는 광택도 산출 단계(S30)를 포함한다.Referring to FIG. 2, in the method for diagnosing hair gloss according to an embodiment of the present invention, the laser light source is matched with a focus on a detection pinhole, the hair is placed on a focal plane, and the image of the hair is reflected through the light reflected from the hair. Hair imaging step (S10) of photographing, an image processing step (S20) of dividing the first region in which the light is reflected and the second region in which the light is not reflected in the photographed hair, and the area of the first region The glossiness calculation step (S30) of calculating the glossiness of the hair through.
상기 모발 촬영 단계(S10)에서는 1가닥의 모발에서 모근으로부터 기 설정된 위치의 모발의 영상을 촬영할 수 있다. 종래는, 두발 전체를 촬영하므로 피험자가 반드시 촬영 장소를 방문해야 했으나, 본 발명의 일 실시예에 따르면 1가닥의 모발의 분석만으로도 모발의 광택도를 측정할 수 있다.In the hair photographing step (S10) it is possible to take an image of the hair of a predetermined position from the hair root in one strand of hair. Conventionally, since the entire hair is photographed, the subject must visit the photographing place, but according to one embodiment of the present invention, the glossiness of the hair can be measured only by analyzing the hair of one strand.
구체적으로, 상기 영상 처리 단계(S20)에서는 모발에서 반사되는 반사광에 의한 상기 제1 영역과 반사광을 제외하며, 투과광 등을 포함하는 광원에 의한 상기 제2 영역을 서로 다른 색상의 픽셀 이미지로 변환할 수 있다. 그리고, 상기 광택도 산출 단계에서는, 상기 제1 영역의 픽셀 값들의 합을 모발 두께로 나누어 모발 광택도를 산출할 수 있다. 여기서, 상기 제1 영역의 픽셀 값들의 합은, 모발에서 기 설정된 영역, 일 예로 모근에서 기 설정된 위치의 모발 영상에서의 제1 영역의 픽셀 값들의 합으로 제1 영역의 면적을 구할 수 있다. 그리고, 상기 제1 영역의 면적을 다시 모발의 두께로 나누어 광택도를 산출할 수 있다.In detail, in the image processing operation S20, the first region and the reflected light are excluded from the reflected light reflected from the hair, and the second region by the light source including the transmitted light may be converted into pixel images of different colors. Can be. In the glossiness calculation step, the hair glossiness may be calculated by dividing the sum of pixel values of the first region by the hair thickness. Here, the sum of the pixel values of the first area may be obtained by calculating the area of the first area based on the sum of the pixel values of the first area in the hair image at a preset area of the hair, for example, the hair root. In addition, the glossiness may be calculated by dividing the area of the first region by the thickness of the hair.
특히, 모발 노화의 의한 모발 광택도를 진단하도록, 상기 모발의 모근으로부터 기 설정된 위치의 모발의 광택도를 산출할 수 있다. 일 실시예에 따르면 모근으로부터 대략 3 ~ 5 cm 지점까지의 모발 영상에서 제1 영역의 면적을 모발 두께로 나눔으로써 모발 광택도를 산출할 수 있다. 모근에서 가까운 영역의 경우, 외부 환경에 의한 영향이 적기 때문에 이 부분의 광택도를 산출함으로써, 모발 노화에 의한 광택도를 진단할 수 있다.In particular, to diagnose hair glossiness due to hair aging, the glossiness of hair at a predetermined position can be calculated from the hair root of the hair. According to an embodiment, the hair glossiness may be calculated by dividing the area of the first region by the hair thickness in the hair image from the hair root to a point of about 3 to 5 cm. In the area close to the hair root, since the influence of the external environment is less, the glossiness due to hair aging can be diagnosed by calculating the glossiness of this part.
또한, 모발 관리에 의한 모발 광택도를 진단하도록, 상기 모발의 모근과 반대방향 끝에서 기 설정된 위치의 모발의 광택도를 산출할 수 있다. 일 실시예에 따르면, 모근의 반대방향 끝에서 대략 5 ~ 7 cm 지점까지의 모발 영상에서 제1 영역의 면적을 모발 두께로 나눔으로써 모발 광택도를 산출할 수 있다. 모발 끝 부분의 경우 내적 요인보다는 생활 습관과 같은 외부 환경에 의한 외적 요인에 영향을 많이 받았기 때문에 이 부분의 광택도를 산출함으로써, 모발 관리 습관에 따른 모발 광택도를 진단해 낼 수 있다.Further, in order to diagnose hair glossiness by hair care, the glossiness of hair at a predetermined position may be calculated at the end opposite to the hair root of the hair. According to one embodiment, the hair glossiness may be calculated by dividing the area of the first region by the hair thickness in the hair image from about 5 to 7 cm from the opposite end of the hair root. The tip of the hair is affected by external factors such as lifestyle, rather than internal factors, so that the glossiness of the hair can be diagnosed by calculating the gloss of the hair.
그리고, 생활 습관에 의한 모발의 영향을 분석하기 위하여, 모근에 가까운 영역과, 모발 끝 부분의 영역의 광택도를 비교할 수도 있다. 모근에 가까운 영역의 경우 외부 환경에 의한 영향을 적게 받은 부분이고, 모발 끝 부분의 경우 외부 환경에 의한 영향을 가장 크게 받은 부분이므로, 이 두 부분의 광택도를 비교하여 생활 습관에 의한 모발의 광택도를 진단할 수 있다.And in order to analyze the influence of the hair by a lifestyle, the glossiness of the area | region near a hair root and the area | region of a hair end may be compared. The area close to the hair root is less affected by the external environment, and the end of the hair is the area most affected by the external environment. Therefore, the gloss of hair by lifestyle is compared by comparing the glossiness of these two parts. Diagnosis can be made.
또한, 조성물에 의한 모발 광택도를 진단하도록, 상기 조성물을 바르기 전과 후의 모발 광택도의 차이 또는 그 변화율을 산출할 수 있다. 조성물을 적용하기 전후의 광택도 값의 차 또는 변화율을 산출하여, 조성물에 의한 모발 광택 변화를 비교할 수 있다.In addition, the difference or the rate of change of the hair glossiness before and after applying the composition can be calculated to diagnose hair glossiness by the composition. The difference or the rate of change of the gloss value before and after applying the composition can be calculated to compare the change in hair gloss caused by the composition.
조성물이 모발의 윤기 또는 광택에 미치는 영향을 분석하기 위하여, 일 예로, 모발의 거칠기와 같은 모발의 표면을 확대하여 분석하는 방법을 사용할 수도 있다. 그러나 모발의 거칠기와 모발의 윤기는 상관관계는 있으나, 모발의 거칠기 값이 크다고 하여 모발이 항상 윤기가 없는 것은 아니다.In order to analyze the effect of the composition on the gloss or gloss of the hair, for example, a method of enlarging and analyzing the surface of the hair, such as the roughness of the hair, may be used. However, although the roughness of the hair and the hair gloss has a correlation, the large hair roughness value does not always mean that the hair is not glossy.
모발의 거칠기 값만으로는 모발이 윤기가 나는지를 평가하기 어렵다. 모발의 거칠기가 모발 전체에 걸쳐 균일한 경우도 오히려 모발에 윤기가 날 수 있으며, 모발의 거칠기가 모발 전체에 걸쳐 균일하지 않은 경우에 모발에서 윤기가 나지 않기 때문이다. 즉, 모발의 광택 여부는 단순히 모발의 거칠기 값만을 비교하여 분석하기엔 부족하다.It is difficult to evaluate whether the hair is shiny only by the roughness value of the hair. Even if the roughness of the hair is uniform throughout the hair, the hair may shine, and the hair is not shiny when the roughness of the hair is not uniform throughout the hair. In other words, whether or not the gloss of the hair is insufficient to analyze only by comparing the roughness value of the hair.
또한, 모발 조성물의 특성상 모발에 도포하더라도 즉각적으로 모발의 거칠기가 변화하지는 않는다. 조성물에 의한 모발 거칠기의 변화를 측정하기 위하여는, 장기간 조성물을 모발에 적용한 뒤에 그 영향력을 분석해야 그 결과를 도출할 수 있다.In addition, even if applied to the hair due to the nature of the hair composition does not change the roughness of the hair immediately. In order to measure the change in the roughness of the hair by the composition, it is necessary to analyze the influence after applying the composition to the hair for a long time to derive the result.
그러나, 모발 조성물의 경우 도포 전/후의 모발 광택의 변화가 있다면 반사광의 값이 변화하기 때문에, 본 발명의 모발 광택 진단 시스템 및 진단 방법을 적용하는 경우 조성물에 의한 모발 광택 또는 윤기의 변화를 진단해 낼 수 있다.However, in the case of the hair composition, if there is a change in the gloss of hair before and after application, the value of reflected light is changed. I can make it.
본 발명의 경우 1가닥의 모발에 대해서도 미세한 반사광의 변화도 측정할 수 있으므로, 이러한 반사광의 값의 변화를 측정하여, 조성물에 의한 모발 광택 변화를 비교 및 분석할 수 있다.In the case of the present invention, even a single change in the reflected light can be measured even for one strand of hair, and thus the change in the value of the reflected light can be measured to compare and analyze the change in hair gloss caused by the composition.
도 4는 본 발명의 일 실시예에 따른 광택 진단 시스템에 의해 측정된 모발 광택도와 모발 거칠기의 상관관계를 나타내는 그래프이다.4 is a graph showing a correlation between hair glossiness and hair roughness measured by a glossiness diagnosis system according to an exemplary embodiment of the present invention.
모발 거칠기 값이 적을수록 모발이 매끄럽다는 것을 의미하므로, 모발에 광택이 있음을 의미한다. 즉, 모발의 광택과 모발의 거칠기는 상관관계가 있다. 그러나, 거칠기 값이 크다고 모발에 광택이 없다는 것을 의미하지는 않으므로, 거칠기 값 만으로는 모발의 광택 분석이 어렵다.A smaller hair roughness value means smoother hair, which means that the hair is glossy. That is, the glossiness of the hair and the roughness of the hair are correlated. However, a large roughness value does not mean that the hair has no gloss, so the roughness value alone is difficult to analyze the gloss of the hair.
도 4를 참조하면, 모발에 대하여 본 발명의 일 실시예에 따른 모발 광택 진단 시스템에 의해 측정된 모발 광택도와 거칠기를 비교할 수 있다. 모발 광택도와 모발 거칠기는 상관관계(R2 = -0.303)가 있음을 알 수 있다. 특히, 모발의 거칠기 값이 작을수록 직선 부근에 점들이 분포하는 것을 알 수 있는데, 모발이 매끈할 수록 모발의 광택이 있으므로, 모발의 광택도 값도 같이 증가하는 것을 알 수 있다. Referring to FIG. 4, hair gloss and roughness measured by a hair gloss diagnosis system according to an embodiment of the present invention may be compared with respect to hair. It can be seen that hair glossiness and hair roughness have a correlation (R 2 = −0.303). In particular, as the roughness value of the hair is smaller, it can be seen that the points are distributed in the vicinity of the straight line.
도 5는 본 발명의 일 실시예에 따른 모발 노화에 따른 광택도 값에 따른 모발 영상들을 나타내는 그래프이다. 공초점 레이저 주사 현미경을 통하여 촬영하였으며, 1024×1024 픽셀의 이미지를 사용하였으며, 256×257㎛ 이미지 크기를 분석하였다. 도 5의 그래프에 대응하는 구체적인 광택도 값은 아래 [표 1]과 같다.5 is a graph illustrating hair images according to glossiness values according to hair aging according to an embodiment of the present invention. The image was taken through a confocal laser scanning microscope, an image of 1024 × 1024 pixels was used, and an image size of 256 × 257 μm was analyzed. Specific gloss values corresponding to the graph of FIG. 5 are as shown in Table 1 below.
나이age 낮은 광택도Low glossiness 높은 광택도High glossiness
25 - 35세25-35 years old 65302 pixel/㎛65302 pixel / ㎛ 98473 pixel/㎛98473 pixel / μm
55 - 65세55-65 years old 45832 pixel/㎛45832 pixel / ㎛ 67549 pixel/㎛67549 pixel / ㎛
상기 [표 1]과 도 5를 참고하면, 낮은 광택도 값을 갖는 경우 모발의 광택이 떨어지고, 높은 광택도 값을 갖는 경우 모발의 광택이 우수하다는 것을 확인할 수 있었다. 그리고 25 - 35 세의 경우의 광택도 값들이 55 - 65 세의 광택도 값들보다 크며, 도 5의 모발 영상을 통해서도 25 - 35 세의 모발 광택이 더 우수하다는 것을 확인할 수 있었다.Referring to [Table 1] and FIG. 5, it was confirmed that the gloss of the hair fell when the gloss value was low, and the gloss of the hair was excellent when the gloss value was high. The gloss values of 25-35 years old are greater than the gloss values of 55-65 years old, and the hair images of FIG. 5 show that the hair gloss of 25-35 years old is better.
도 6은 본 발명의 일 실시예에 따른 모발 광택 진단 시스템을 통하여 조성물(미장센® 헤어 에센스)을 도포하기 전/후의 모발 영상을 나타내는 사진들이다. 공초점 레이저 주사 현미경을 통하여 촬영하였으며, 1024×1024 픽셀의 이미지를 사용하였으며, 256×257 ㎛ 이미지 크기를 분석한 것이다.Figure 6 is through the hair glossy diagnosis system according to an embodiment of the present invention composition (® mise en scene hair essence) are a photograph of the hair images before / after applying. The image was taken through a confocal laser scanning microscope, an image of 1024 × 1024 pixels, and an image size of 256 × 257 μm was analyzed.
조성물 도포 전의 광택도는 83406 pixel/㎛이었고, 도포 후의 광택도는 117620 pixel/㎛이었다. 광택도가 41.02% 증가한 것을 확인할 수 있었고, 도 6의 도포 전(a) 모발 영상과 도포 후(b)의 영상에서도 모발 광택의 증가를 확인할 수 있었다.The glossiness before application of the composition was 83406 pixel / μm, and the glossiness after application was 117620 pixel / μm. It was confirmed that the glossiness increased by 41.02%, and the increase in hair gloss was also confirmed in the images before (a) and the images after application (b) of FIG. 6.
