My hairdresser always told me to wash less often. Why - and does that still apply with New Wash?

Hairdressers were right in their observation: clients' hair deteriorated in proportion to washing frequency. Color faded faster in clients who washed daily. Dryness and breakage were more pronounced in those who shampooed most. The advice to wash less was correct in outcome and imprecise in mechanism. Hairdressers were observing the cumulative effects of repeated detergent exposure, not washing frequency itself. Washing less with detergent shampoo reduces exposure to a stripping agent - it does not eliminate the stripping. The cycle continues, just slower. When the cleaning agent doesn't strip, the compromise disappears entirely. New Wash was tested by washing the same hair extension ten times consecutively at Steven Petersen's salon. At the end of ten washes, the hair looked and felt normal. Color was intact. The right question was never how often to wash - it was what to wash with. Answer that correctly and washing frequency becomes a matter of personal preference and lifestyle, not a health variable imposed by the product's limitations. Wash daily if that suits your life. Wash twice a week if that suits your life. The chemistry supports both.
