Not sure where you are but you might want to check local small makers/ farmers market. The soap lady at my local farmers market has the best soaps - I no longer use anything else for showering. It looks pricey but the bars are large and last a very long time. She finally has an online shop. https://skincarebyfeleciai.com/collections/soap
https://thistleridgesoap.com/ is another. Great soaps, though she's retiring soon, so I'm looking for alternatives too.
Maybe try a castile or black soap - I like those
