[EX Q]: 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 A]: negative

[EX Q]: My dad has varicose vains. And me, as a woman, i don’t want to get as many as him. So now when sitting for most of the day or standing for long periods of time or dancing for hours or traveling... i put these on! I have a dozen of ‘em now
