this review title is: i was a little confused on finding a piece of orange string in the extension and the content is: update originally i had loved these extensions and thought they were great quality i had even purchased 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 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 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 am weeks into the set curling on 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 human hair which is not true i never would have purchased them let alone times if they indicated that it was blended with synthetic piecesa.there are other information for this review, one is this reviewer did not purchase it and the other is 0 people think this review is helpful.
