How long do fusion hair extensions last?

The length of time that fusion extensions last will vary from person to person depending upon how quickly their hair grows. 

It will also depend upon the quality and length of the extensions, but with a good quality set they could last from 3-6 months. 

As the bonds grow out with the hair they can be removed and reapplied closer to the scalp. This should typically be done every 4-6 weeks as at this time the bonds become visible from the grow out.
