I have relaxed hair that I straighten so decided to go with the think silk bundles. They straighten really well, hold a curl nicely, a bit of shedding but nothing out of the ordinary. Had experienced really bad bundles before from several other companies and have to find myself replacing them every month or so but these are so affordable and I can see them lasting a long time. I have 16” & 18” but will be ordering 14” too as I’d like my next install a bit fuller. Dispatched really fast too. Customer service always up to par.
