These extensions are hands-down the best I've ever ordered! They arrived on time and came in branded packaging that kept the hair fresh and secured. Installing them as a weave was tricky because the wefts are thick but the outcome was fantastic. I got the Think Silk Bundles and the Think Silk Closure. I only needed one bundle of hair each (i.e. one bundle of 18-inch hair and one bundle of 20-inch hair) which gave me the full look of hair you see in the photos. (Note: if you want one length of hair for your installation or if you want to make a wig, get two bundles. So if you want to make a wig that is 20 inches long, buy 2 bundles of 20 inches). The hair mimics straightened relaxed hair perfectly, there's no tangling or shedding and it flows beautifully as you walk, especially if you're outside and it's windy. I've washed the hair and again, there were no issues. It dried straight so I didn't need a hair dryer or straightener. Overall, I absolutely love the brand and will be a lifelong fan going forward!
