Raw hair and grade hair are two terms commonly used in the hair extension industry to describe the quality and processing of the hair.
Raw hair refers to hair that has not undergone any chemical or steam processing. This means that the cuticles of the hair are intact and aligned in the same direction, which makes the hair less prone to tangling and matting. Raw hair is usually sourced directly from donors and is considered to be the highest quality of hair available. Because it is unprocessed, it is also more expensive than other types of hair.
Grade hair, on the other hand, refers to hair that has been processed to some extent. This may include chemically treating the hair to remove the cuticles or altering the texture of the hair with steam or other methods. Grade hair is usually sourced from multiple donors and is often less expensive than raw hair. However, because it has been processed, it may not be as durable or long-lasting as raw hair.
In summary, raw hair is unprocessed and considered to be of the highest quality, while grade hair has undergone some processing and may be less expensive but may not be as durable.
