The quality and upkeep of clip in hair extensions have a significant impact on how long they last. High-quality extensions made from 100% human hair typically last between six to twelve months with proper care, but this can vary based on usage frequency and maintenance routine.

To ensure longevity:
- Minimize Heat Styling: Overuse of hot tools can weaken the strands. Opt for heatless styling methods whenever possible.
- Gentle Washing: Wash the extensions only when necessary, using sulfate-free shampoos and conditioners to maintain their texture and shine.
- Proper Storage: To prevent dust and tangles, keep your clip-ins in a cool, dry location, ideally in a breathable storage bag.
- Brushing Technique: Use a comb or a brush designed for extensions to gently detangle them, starting from the tips and working your way up.
- Avoid Sleeping with Clip-ins: To avoid putting undue strain on the hair and clips, always take them off before bed.
With attentive care, your clip in hair extensions can maintain their usefulness and beauty for a very long period, offering you countless styling opportunities!
