Yes, the hair can be dyed as it is human hair. But there is a general rule that hair can be dyed from lighter color to darker color. And we suggest you to ask the professional hair stylist to dye for you, Always try a small strand of hair when you dye it.
General Speaking the hair extensions can last for 2 to 4 months. The virgin hair could last at least 6 months (if you take good care of it, it can last for a year) Your personal care also matters the life of the extensions. In a word, the more you look after them the longer they will last.
You can choose the hair according to your hair color. If you are still not sure which color matches you, please do not worry, color matching service is available, feel free to contact us: firstname.lastname@example.org
