This wig started out beautifully. Then it started shedding three days later. After shampooing and conditioning according to the instructions it became a stiff mess .The curls were no longer bouncy. It is dull, stiff and lifeless. I have lace front wigs I paid less money for that are still beautiful after 6 months and several shampoos. I am so disappointed with this purchase! I will never purchase another wig from Amazon!

Ex Output:
negative


Ex Input:
It does it's job however it does leak and against my better judgement after reading the reviews I had to try it myself and of course this is just a leaky mess but it does steam and does iron and I only can pour lil amounts of water at a time to prevent bad leakage

Ex Output:

negative
