Hair extensions are of multiple styles including tape-ins, clip-ins, fusion, pre-bonded, micro-link, etc. There are synthetic hair extensions and actual human hair extensions. Both are different.
Human hair extensions
These are made from hair collected from a donor.
All the cuticles are intact and run in the same direction when collected.
Therefore, extensions remain tangle-free, silky and smooth through its lifespan.
They look and feel real, so blend naturally with your own hair. You can straighten, blow dry, color, and use hair products.
Human hair extensions are costly but last longer with proper care.
Synthetic hair extensions
Various synthetic fibers are blended, which are very thin designed to imitate genuine human hair.
However, synthetic is stiff and feel different than natural hair.
They cannot blend completely with your own hair.
Synthetic hair cannot be colored as most dyes include bleach or ammonia, which damage them.
Heat from blow dryers, straighteners, or curling irons can destroy synthetic hair.
Synthetic hair is cheap but does not last long in comparison.
