What I do is I start detangling from the bottom up. I'll hold my hair still a few inches up with one hand, that way when I detangle the bottom it won't tug on the roots and pull out hairseseses. . . then I just rake very gently with my other fingers and when I hit a knot I first rinse with water and then add extra conditioner, teasing the knot with the tips of my figners and plucking it (I guess you could say "pick") so that I can unravel it very, very gently. Once I've sufficiently detangled the first bottom few inches of my hair I work my way up.
