Some shampoos that are designed to add shine and control to gray hair are Clairol Shimmer Lights shampoo, Phytargent Whitening shampoo and Artec White Violet Color shampoo. In addition to giving gray hair shine and manageability, these shampoos also prevent the hair from yellowing.
To ensure that the shampoo being used provides the desired level of brightness, begin by mixing equal parts of the shampoo with a regular moisturizing shampoo to get used to the product's effects on the hair. Continue to experiment with the amounts until the desired effect is achieved. If the hair begins to take on a purplish cast because of the shampoo's effects, switch to a shampoo that has a clarifying and/or moisturizing formula. Alternate between the two types of shampoo to achieve the optimum results.
