Review title is I was a little confused on finding a piece of orange string in the extension [SEP] **UPDATE**<br /><br />Originally I had loved these extensions and thought they were great quality. I had even purchased 2 additional sets for future use. After a few weeks, my original set started to feel dry, which I assumed was from curling the hair. I removed the extensions, gave my hair a break, and proceeded with the 2nd set. I did not use any heat and even wore a silk bonnet to sleep to keep the quality of the hair in good condition to last longer.  1 day shy of a week I had to remove them, and was so confused as to how this set was in worse condition and had been cared for better. Now I'm 1 1/2 weeks into the 3rd set, curling on 225° heat, using heat protection spray, and notice that there are strands melted throughout. I am so disappointed because this seller advertised that these extensions are 100% human hair, which isn't true. I never would have purchased them, let alone 3 times if they indicated that it was blended with synthetic pieces.a
