Q: I want to use a color enhancing shampoo for brunettes, but I have blonde highlights at the front of my hair! Would the shampoo affect my highlights?
A: The amount of tint contained in color-enhancing shampoos is minimal, but it could affect the color of your highlights over
repeated uses (depending on the porosity of the highlighted hair). However, you can counter possible color absorption by applying
conditioner to the highlights (if they are big enough that you can isolate them) and clipping them out of the way, before using the shampoo.
If the highlights are too diffuse to be isolated, or there are too many to make doing this practical, I suggest that you
try the shampoo and, if you find the highlights to be too heavily affected, discontinue using it. The color in these enhancing
shampoos is temporary color and the effects will dissipate when you stop using them.
However, you may find that the shampoos effects aren’t that noticeable in your highlights, and
that the highlights only become slightly more subdued and subtle. It may be an effect you can live with. In this case, provided you
like the results on the rest of your hair, you may be willing to accept the slight change in the highlights. Either way, the
color-enhancing shampoo shouldn’t cause any permanent color change in the highlights.
