I've never tried Giovanni, but yeah thats how my hair felt when I was using a conditioner with protein and mineral oil.

and yes the product that worked for me was the Shea Moisture with the yellow label...the one that comes in the jar. I also tried their other shea butter conditioner with the pump, but that also caused breakage for me due to the coconut oil, another ingredient that my hair does not like.

once I eliminated protein, mineral oil, and coconut oil from my regimen I noticed my hair was a lot softer and moisturized.
