What’s your Favorite Shampoo

I’m looking for some recommendations! I love amika and use their purple shampoo, but I’m looking for another shampoo to use in between purple washes. I’ve been using the Verb curl shampoo but I don’t know if I’d buy it again.

What shampoos do you all use/ recommend? Is it worth it to get a specifically curly shampoo? Bonus points if it’s cruelty free!
