Clip Problems
What if the clips are loose/not working/broken?
What if I have less hair that will show the clip?
Will the hair extensions fall out after wearing them?
Wearing Problems
How long do the hair extensions last?
Can I sleep with my hair extensions?
Can I swim or exercise after getting hair extensions?
Hair-Volume problems
Why is it still not full enough after wearing it?
Can I use clip ins with very little hair?
Why does it look bulky after wearing it?

You can still leave questions related to clip-ins in the comments section of this post and I will keep updating it.
