Q5: Can I dye/color the hair?
A. Yes. The hair is made of 100% 100% virgin Brazilian/Malaysian/Indian/Vietnamese/Burmese/Chinese human hair, so they can be colored. As a general rule it is easier to darken the hair than to lighten the hair. We recommend dyeing darker, since it is difficult for the original color to fade. Improper dying will ruin the hair. We highly recommend you to ask for help from your hairdresser.

A: There might be color difference between different monitors. You could dye the hair if you need different color.
Q7: How to tell human hair with synthetic hair?
A: human hair has natural protein. It is easy to tell by burning and smell. Human hair will be ash, which will go away after pinching. Human hair will smell foul. When burning, the human hair will show white smoke.
While synthetic hair will be a sticky ball after burning and will show black smoke. Moreover, human hair may have very few gray hairs and split ends. It is normal and not a quality problem.
