About the hair quality and mainly getting all the different colors, our factory uses a really long process with super gentle products to keep the hair as soft as possible and make sure its quality stays top notch. We then apply permanent coloring while carefully following the color system we've set up. Before putting the hair on the base (polyurethane or lace), it goes through a silk protein bath for several days so it gets even softer.
We use Indian quality, which is one of the best you can get right now. Hair in India is barely damaged by things like coloring or bleaching, so it really lasts a long time.
