You will probably find that the quality of the hair is less than a regular MLP - cheaper nylon. The quality of the hair is is going to depend on how it will react with temperature. I have heard of fakie hair melting together but likewise so will MLP hair if exposed to too much heat. If you are worried and if its just a crinkle I would try the hot water dip method first. You should be fine with water just off boiling but if you are concerned simply start of at a lower temperature and work your way up if the lower temps dont work.
