Hair Care Product Claims 516 modified hair tress holder for use with the commercially available equipment that allows hair to be combed into position prior to measurement. Thus, improved alignment resulting from the use of conditioning products can give rise to significant, although not especially sizable, increases in technical shine. There appears to be little doubt that hair care products do indeed provide definite consumer-perceivable benefits in terms of shine, yet, as seen in the discussion on frizz, the ability to technically measure this benefit is not necessarily straightforward. The application of generous quantities of various oils to the hair surface can smooth out asperities and irregularities to produce readily measureable increases in technical shine, yet conventional shampoo and conditioner treatments are not likely to show benefits by this traditional method. Nonetheless, it can be demonstrated that shampoos alleviate issues associated with buildup of dulling surface deposits, while conditioners aid with manageability which facilitates the creation of fiber alignment in hair styles. Again, the many variables that contribute to technical shine measurements can produce a disconnection to real-life observations however, it appears that the magnitude of any claimed benefit should be in-line with consumer perception. Color Fade Chapter 4 outlined the functionality behind permanent color products and described how dye precursors permeate into the hair, where they react and become larger pigmented molecules with a reduced tendency for diffusing back out. However, Figure 16 shows rinse water for permanently dyed hair as a function of washing cycles and demonstrates how color bleeding does indeed occur. Consequently, hair treated by this approach will gradually fade in color from the freshly treated state. This is an undesirable occurrence which possesses a number of different contributors. Firstly, it is widely believed that shampoos are able to strip color from hair. Again, the purpose of these products is to solubilize hydrophobic surface materials and allow their removal. Accordingly,
