How long your unit last depends on several things. The quality of hair used, usage, handling, care and removal practices. The appearance of the hair on our Indian human hair units can last 3 to 6 months or more, it’s important to take special care of the hair as your own. The hair on our Remy hair units can last for years with proper conditioning and maintenance due to quality of hair, it is also important to take special care of the hair as your own. Following the care instructions listed here and using suggested products will extend the life of your unit. Just like with shoes, it’s best to have more than one in your “hairdrobe” to rotate.
