I have two synthetic wigs that have been frizzing and yesterday I watched a you tube video on how to get rid of the frizz and it worked!! You need a steamer and comb. Comb through the hair until smooth and then put the comb underneath and put the steamer just off the hair and pull the comb and steamer down to the end of the hair. It will straighten the hair, but I was able to do it again and roll the hair under and it looks great! The wigs are looking like new again.
