Taming Your Mane

Hey there furry friends.  I know some of us can be serious product junkies.  We look under our bathroom sink and see that we have become our own CVS hair care aisle.  So my question is, what makes you try a product?  Is it word of mouth, cost, ingredients, or the name or brand?  I recently tried Cantu Shea Butter Leave In Conditioning Repair Cream.  My reasons: word of mouth- I've heard good things about this brand; and cost- it's a little pricier than I'd like it to be but it came in a decent size.  So far, I am very pleased with it.  It helps with detangling, smells really nice, and leaves my hair silky without feeling heavy or greasy.  It does however have a residue.  What do you guys think?
