after getting the knot out, the hot water should smooth out most of the frizz... my friend has saved our Grell's wig like that, and trust me... it was MUCH worse then this... (you still have some resemblance of hair, this was one big dreadlock...) just put a sh*t load of conditioner through the wig, poor the water on it and comb it out gently... people will tell you to 'never comb a wet wig' but I call bullish*t every time because we do that with all our long wigs after every use and we have yet to lose a long wig... it doesn't stretch the fibers, no more then normal combing does, and actually LESS because the brush glides through easier...
