They can be applied and removed very quickly and are perfect for adding short term color, length and/or volume to your hair.

 

Loop extensions are one of the fastest ways to apply fusion extensions. There are the loop extensions with the micro ring and the loop extensions with the teflon tube that is melted onto your hair. Please feel free to click on the below links to read the articles that we have written about the loop extensions:

But, again, to answer your question, the weight should not be too noticable if you are only adding highlights, not length or volume. If you have very short, thick hair and wish to add 18" hair that is much longer and fuller than your own, weigh might be a concern, not with highlights or clip-ins.
