I have purchase the 14 inch twice and each set last one year. The first thing to remember is you have to treat the hair the way you treat your own hair. I use very good products on my hair and that's the same products I use on the hair. I wash it once a week, condition it and I put a gel like oil on it when it's wet and my goodness everyone will complement me about how beautiful my hair is. This air is not for everyone as for myself, I love it and I am going to continue to buy it and I hope they don't run out of the hair. One more thing my sister does not like weave and when she saw me with it, her comment was "That's the best hair and weave I have ever seen you with, you should always wear that hair.
