@mpq39 I agree with the amika Blonde Bombshell Bust Your Brass Set  or Olaplex No.4P Blonde Hair Hydrating & Brightening Purple Toning Shampoo 8.5 oz/ 250 mL  

Both work really well. My stylist prefers Olaplex.

@mpq39  The best thing would to be using a purple shampoo. I have blonde in my hair and when it starts to look brassy or dull I use amika Bust Your Brass Cool Blonde Strength Repair Shampoo​   I try not to use it to often since it drys my hair out but it will bring life back to the blonde!
