Is there a 2in1 shampoo and conditioner that Ctually works as well as separates?

Because 2 in 1s generally seem to make my hair look dull and heavy, and not do the conditioning job very well either.

Any recommendations? I have quite thick long hair with highlights.

Thank you!

Nope.

2nd the nope.
It's just crap for your hair, there's a reason why it was a short - lived fad.
