This study was to investigate effects of Curcuma longa L. (C. longa) on the damaged hair caused by repetitive permanents. For this, we have examined physical and morphological changes of damaged hair when pre-treated with C. longa and Poly Peptide Treatment (PPT) and post-treated with C. longa and SPA-T3 (Hair Recovery SPA Treatment 3). Also, the absorbance, tensile strength, and elongation rates were compared with each samples. After performing the tensile strength test, morphological changes of each were also observed by electron microscopy. As the frequency of permanent was increased, the absorbance value was increased from 0.078 to 0.170 and 0.280, and the tensile strength value was reduced from 158.17 to 132.65 and 12.31, indicating that levels of hair damage in each sample were gradually increased. The absorbance of hair sample treated with C. longa before repetitive permanents was reduced more than the one treated with repetitive permanents without C. longa. Also the former`s hair tensile strength value was increased more than the latter`s one, so the results showed that the C. longa treatment before repetitive permanents had certain effects protecting hair. For the case of 3-time permanents and then received C. longa and SPA-T3 treatment, the absorbance of the former panel only received 3-time permanents was decreased into 0.355, and the latter panel received C. longa treatment into 0.208. For the tensile strength values, the former panel with only 3-time permanents was increased into 121.32, and the latter panel with C. longa was increased into 128.90. These results showed that treatment with C. longa has certain effects protecting the hair. As the result observing the hair`s side and fractured side, the former panel hair was seriously damaged, its coherence was weaken, and separation was occurred between epidermis and cortex of hair. Contrary to these observations, the latter panel was observed that the float phenomenon became less in the epidermis of hair and the damage of cell membrane complexes between hair cortex was low. It is therefore considered that a product using the C. longa added to keratin and other nutrients will be used as a hair treatment goods caring damaged hair resulting from repetitive permanents as well as managing the hair`s epidermis-related troubles. |
