Adding castor oil to your hair along with your cheap conditioner may give it more slip power (the ability to make the shingles on the hair shaft lie down so the strands will slide by each other and tangle less). There may be a definite method to making this trick work.
Spritz a tangled section of hair (no bigger than 3x3 inches) with water. Slather about a quarter size dollop of castor oil directly to the hair. Top that with the same amount of conditioner. Detangle the section starting from the ends.
I purchase my castor oil from Walmart (near the vitamins) OR a health food store.
