I have the Papaya Souffle and the Brazil Nut Buttercream. I think those are the names.
I'm not sure about the Papaya Souffle. It feels good, like the product line tends to feel on my hair. However, I suck at curl defining in general, so I don't know if it's doing well or not. The packaging seems to recommend it for twistouts/braidouts however.
I really like the moisturizing qualities of the BN Buttercream. I mentioned this in the Vendor Forum. I think it does a very good job of adding moisture and softening my hair. It feels different on my hair than the Seyani butter. The seyani butter seems more of a sealant in comparison where BN BC seems to be more moisturizing. Makes my hair soft.
