First of all I chose 3 day delivery and it took darn near a week and a half to get here. I could not locate any information on the seller and when I emailed them twice, I never got a response. When tthe product finally arrived, I tried it and it didnt work at all. The hair was very loose and within the 1st hour, it became dettached. Ive been doing hair for many years. I would not recommend this product to anyone. Save your time and money!!!!!!
