Effect of rinse-off hair conditioner containing argan oil or camellia oil on the recovery of hair damaged by bleaching

Effect of hair conditioner formulated with Argan oil or Camellia oil was investigated on the protection of hair damaged by bleaching. Six different rinse-off type hair conditioners were made with the basic ingredients of hair conditioner and one of the following conditioning agent; Argan oil (AO), Camellia oil (CO), Palmitic acid (PA), Stearic acid (SA), Oleic acid (OA), and Linoleic acid (LA). L*, a*, b* color values and tensile strength, elongation were measured, and the amount of protein leak was examined using the Bradford Protein Assay. Statistical significance was tested using the SPSS statistical software. Although both AO and CO were effective in protecting the tensile properties of bleached hair, significant effects were observed with AO in enhancing the tensile strength and retaining the color of bleached hair. This might be due possibly to the difference in the composition of four major fatty acids in Argan oil and Camellia oil.
