As bad as P5 is I do not think this is bug but a result of the overly complex hair system. It looks like the hair is made of two peices when you clothify it the hair splits apart. Two solution will be to 1) set teh whole object at "decorated soft" or constrained 2) clothify only the sides and keep the seam area set at normal or at "decorated soft" or "constrained" this is the best option and teh most realistic I think. PS Like the 'do. Kinda like an inverse mohawk befitting an alien.
