Sometimes what i do with my clients when the hair is going in a weird direction is to take a hot hair dryer and a comb or brush, and blow hot air directly at the roots(knots) and comb or brush them in the direction i want them to go...all the time moving the dryer around to avoid melting the lace or burning the hair...the hair should be damp when you do this...this usually works, and even after the unit is washed, the hair usually stays in the direction you directed it in...
