I believe I could comfortably wear this hair for at least another hair bundles sleep in my units. The hair took color well. I used human hair wigs and also a protein filler when I applied the color. I hair dried the hair bundles uk and used a color sealer. It had a bit of human hair wigs that not really a bit deal. It was shedding after all the chemical processing but I sealed the hair bundles anyway with fray check. I will soon install it and give an updated review but so far so good.
