Cocoa butter is as moisturizing as shea butter but lacks the many additional benefits of shea butter.
Shea butter has many qualities which aren't found in other butters.
If you are just looking for a good moisturizer, you can try cocoa butter instead.
I find mango butter to be a bit heavy but sometimes you need something with a little oomph. A few months ago I purchased 2 mango butters from Kyra's. Both smell great and moisturize very well.
Hate to bump a super old topic but I too am looking for a replacement for shea as for as performance is concerned. I like the hold but not fond of the waxiness. I heard mango butter was a good replacement?
