i was a little confused on finding a piece of orange string in the extension [SEP] 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
