Unwanted golden or yellow tinges are minimised, & the silver hue is intensified in greying & platinum blonde hair. As well as perfect colour care, the p H 4.5 Colour Freeze Silver Shampoo strengthens the hair structure & gently yet effectively cleanses the hair & scalp. Work the shampoo into a lather in wet hair & rinse away.
