Here's the breakdown:
* Human Hair: This simply means the hair comes from a human donor. It can be of varying quality, depending on how it was collected, processed, and treated.
* Remy Hair: This is a higher quality type of human hair. It's collected in a way that keeps the cuticles (the outer layer of the hair shaft) aligned in the same direction. This results in smoother, less tangled hair that looks and feels more natural. Remy hair is typically considered to be more durable and have a longer lifespan than other types of human hair.
Here's how to think about it:
* Human Hair: The general term for any hair sourced from humans.
* Remy Hair: A specific sub-category of human hair, with higher quality and better alignment of cuticles.
Therefore, all Remy hair is human hair, but not all human hair is Remy hair.
