무운산 추출물 함유 트리트먼트의 모발 보호 효능

Abstract

This study attempted to investigate the possibility of using Muunsan extract as a new natural cosmetic ingredient by preparing a hair conditioner containing such an extract, applying it to permed hair, and analyzing its effects with the goal remedying subalhwangrak (yellowish and gray hair losing gloss and smoothness) as defined in oehyeongpyeon (external medicine) of the Donguibogam (Korean medical encyclopedia). According to measurements, ‘V’ was the greatest, followed by ‘C-2’, ‘C-1’, ‘B-2’, ‘A-2’, ‘B-1’, ‘A-1’, and ‘C’ in terms of hair thickness and tensile strength. In other words, ‘C-2 (hair post-treated with a hair conditioner containing Muunsan extract)’ was the best, following only virgin hair in terms of hair thickness and tensile strength. In terms of absorbance, ‘C’ was the highest, followed by ‘A-1’, ‘B-1’, ‘A-2’, ‘B-2’, ‘C-1’, ‘C-2’ and ‘V’. In other words, ‘C-2’ was the lowest, following only virgin hair in terms of the damage index. According to the analysis of cuticle with SEM(Scanning Electron Microscope), scales were most firmly adherent to the scalp and associated hair in ‘C-2’ as exfoliation and unevenness were low. When essential hair components were analyzed by EDS(Energy Dispersive X-ray Spectro mrtry), ‘V’ was the highest with 6.37%, followed by ‘C-2’, ‘C-1’, ‘B-2’, ‘B-1’, ‘A-2’, ‘A-1’ and ‘C’ n terms of sulfur (‘S’) content. The above results proved the hair protection effects of Muunsan extract and confirmed that it would be viable as a new ingredient for hair cosmetics.
