I have a dark/medium blonde and notice at times either a little brassy tone and lately it actually looks like it has a slight green tint compared to my natural hair.

Any ideas on how to remedy this? My cut-in stylist recommended Shimmer Lights to cut down on brassy tones, but would that do anything about greenish tones?

Hi Rashton,
Could be chemicals in your water. We always recommend a charcoal shower filter to get the chemicals out of your water. It's good for hair and skin too. You can pick one up at Home Depot or Lowe's for about $40. A great product for restoring color is 'Back 2 Natural' from adfhair.com. It's specifically formulated to restore the color of hair systems. Just put some on a comb and run it through your hair--it's excellent.
Regards,
John
