Even though menopausal, I have the misfortune to have ultra-oily roots and straw-like ends from over 25 years of dyeing grays. Regular shampoos which clean my scalp strip the colour. Shampoos for coloured hair inadequately clean the roots, meaning I have to wash my hair more frequently, thereby… stripping the colour.
Are there any shampoos that both properly clean and are gentle on colour???
