My hair HATED the one CV bar I tried--it made my hair tangled, too. So, I got rid of all the bars I bought. My hair only tangles when I use an ingredient it didn't like. I narrowed it down to the castor oil. Checked the ingredients for the bar you used:
Ingredients: african shea butter, coconut oil, palm oil, water, vegetable glycerin, palmitic acid, vanilla extract, sodium chloride, argan oil, chamomile, mineral and vegetable pigment
I'm thinking it may be the castor oil your hair doesn't like, either.
