The lifespan of hair extensions depends on several factors, including the type, quality, and installation method. Here's a general overview of how long different types of hair extensions can last:
1. Sew-in or weave hair extensions: These extensions can last anywhere from 6 to 8 weeks, at which point they'll need to be removed and reinstalled to avoid damage to your natural hair. The hair itself can last up to a year or more with proper care.
2. Tape-in hair extensions: Tape-ins typically last 4 to 8 weeks before needing to be removed and reinstalled. With proper maintenance, the hair can last 6 to 9 months or even up to a year.
3. Fusion or pre-bonded hair extensions: These extensions can last 3 to 4 months with proper care. After this time, they'll need to be removed and replaced, as the bonds may start to break down.
4. Clip-in hair extensions: Since clip-in extensions are not worn permanently, they can last anywhere from 3 to 6 months or up to a year or more with proper care, depending on the quality and how often they're worn.
5. Micro-ring or micro-bead hair extensions: These extensions can last up to 6 months with proper care. The beads will need to be repositioned or tightened during maintenance appointments every 6 to 8 weeks to prevent damage to your natural hair.
Keep in mind that the longevity of hair extensions can be affected by factors such as the quality of the hair, how well they're maintained, and your natural hair growth cycle.
