F A Q: 
Q: Is your hair of same length? 
A: No, most of our hair extension follow standard proportion in length, for example in 20" hair extension, there are 30% hair in 20" and others are shorter. It is similar with natural human hair.But we could customize for you as your request of hair length. 
Q: Can they be straightened, curled ? 
A. Treat the hair as if it is your own. Use a flat iron/ straightener or tongs, even when fitted, but as with your own hair, never use hot tools too often as you could dry the hair and it will not last as long. 
Q. Can I dye /color the hair? 
A. Yes. The hair can be colored. As a general rule it is easier to darken the hair than to lighten the hair. We recommend to dye darker , not lighter since the hair extension has been processed and colored, it is difficulty to fade the original color. Improper dying will ruin the hair. We highly recommend having your hairdresser dye the extensions as you will get the results you want, coloring them yourself always poses a high risk of not coming out the shade you want. If you can't get to a salon, always use a good quality hair dye and test a small sample first. Virgin hair is not processed chemically and it keeps cuticle intact. you can dye it any color, either darker or lighter. 
Q. Can I wash & blow-dry the hair extensions? 
A. You can wash them as you would your own. Shampoo and conditioner. We also recommend using a hair treatment on them every few weeks, because the hair is not attached to your scalp, it is not getting the oils it should be. Using a treatment/hair mask will help keep them looking healthier and shiny for longer! You will find that you don't need to wash your extensions too much, about every 3 weeks. The extensions can be blow-dryed on low setting, but it is not recommended to do it too often. It is best to let your hair extensions dry naturally after washing them. please comb from bottom to top. 
Q: 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 hair and split end. It is normal and not a quality problem.
