Abstract:
Different kinds of silicones were incorporated directly into permanent and semi-permanent hair dyes. To ensure that the silicone was deposited to the hair fibers Si deposition was measured. Hair treated with a silicone free control or the silicone modified hair dyes was tested for color and lightness change (fading) by washing the treated tresses several times and measuring the color change. In a second experiment, hair treated with permanent hair dye was treated with UV radiation to show if silicones can reduce the color change initiated by UV light. The influence of the silicones to dry combing forces of permanent dyed hair untreated and treated with UV was also investigated. The tests showed that dimethiconol/dimethicone mixtures can reduce the washout of hair colorant clearly and silicone resins like trimethylsiloxysilcate or propylphenylsilsesquioxane are able to decrease the color change occurred by UV radiation in dyed hair.Document Type: Research article
