As the title says, I'm looking for recommendations to protect colour-treated hair; it must be cruelty-free. Thank you!

No SLS is the best choice, as that strips colour apparently.
Liz Earle do a nice shampoo and conditioner, and is cruelty free.

Those Liz Earle products look nice, but they don't seem to do one for colour protection...

I like tresemme. I'm not sure if it's cruelty free though.

TiGi Oatmeal and Honey is fab

Thank you all
