How do you make old hair highlights appear newer?

== == Go to any beauty salon and ask them for their best products. The products you buy in your local super markets or even drug stores can contain detergent in them. I buy the 'AG' products and have highlights in my hair and I'm pleased with this product. I also use the mousse and the hairspray. You can also try shampooing with Shimmer Lights Shampoo. This is a purple shampoo that will help take away the brassiness and will brighten your highlights. Read the manufacturer's directions first.
