The lifespan of machine wefts depends on several factors, including the quality of the hair, how well they are maintained, and how often they are worn. In general, good quality human hair wefts can last up to 6 months or more with proper care and maintenance. They can also be reusable multiple times, we have some Perfect Locks customers using their wefts for 5+ years!
To ensure that your machine wefts last as long as possible, it's important to take good care of them. This includes regularly washing and conditioning the hair, avoiding styling with too much heat, and brushing the hair gently. It's also important to avoid sleeping on wet hair, and tying it up tightly, as this can cause damage to the hair and shorten the lifespan of the wefts.
It is also recommended to have regular maintenance checkups with your stylist, around every 6-8 weeks, to ensure that the wefts are still secure, and any shedding or tangling is being taken care of.
Keep in mind that even with proper care and maintenance, hair extensions will eventually need to be removed or replaced. The actual time it will last may vary depending on how well it was maintained, how often it was worn, and your own hair growth and shedding.
