Best shampoo to fight brassy blonde (for non-natural blondes)?

[cadabeijo]

Hi guys! I'm a natural brunette with dyed blonde hair, but have struggled to find the right blue shampoo that actually removes the brassiness. Any suggestions? So far I've tried Sachajuan, DPHue, and Drybar, and none seem to do much for the brassy tones.

My new favourite for my blonde hair is Amika Bust Your Brass. I've tried nearly every blonde shampoo/conditioner out there and I find this one really works. It is a bit drying for my hair so I only use it every 2 weeks. Hope this helps!

I recommend Keratin Complex Blondeshell.
