New shampoo and conditioner

I’ve used Rëzo Curl Manifest Shampoo and Conditioner for about two years and I absolutely love it but I am running low and for months now the Rëzo website has been down and none of their sellers are actually selling any products and say it’s unavailable.

I’ve had such great progress with my hair and don’t want to ruin it by getting an unfit shampoo and conditioner.

I have pretty lightweight 3c curls so I can’t really use anything too heavy which is what I liked about Rëzo but it was also not too flimsy because I live in a humid climate.

Does anyone have good alternatives?
