I have been asked several questions about the grading system of hair. To answer all the questions, I thought about blogging on this hot topic. First, the hair grade system is used to determine the quality of hair used for making extensions. The quality also shows that all of the hairs are close to the same length, don't have split ends or damage. The higher the grade of hair, the more time taken to make sure there are no imperfections. The grading starts from 3A, 4A, 5A, 6A, 7A, 8A and latest 9A. We will go through them one by one.
3A GRADE-3A grade stands for no shedding and no gray hair. These are sometimes mixed with synthetic or animal hair. With 3A grade, the hair cannot be bleached, dyed or styled because the cuticles have been removed or damaged
4A GRADE-4A grade maintains all the standards of 3A but in this, the cuticles are fully intact so the hair can be bleached, styled and dyed. The hair cuticles are facing different directions so the hair tangles, sheds and becomes frizzy in about four weeks.
5A GRADE-5A matches 4A; in this, the cuticles are in the same direction. However, the quality of the hair is very poor because the bad quality of hair is mixed with leftover good quality. The hair shaft is very thin. As the hair is from many donors, so it is hard to manage and the hair reacts differently to the elements of nature. It can be dyed up to a medium brown color.
6A GRADE-6A grade maintains the quality; in this, the hair is from three donors with more or less same hair type. This is a 100% Remy hair with a medium hair shaft. This hair can be reused several times and generally last up to six to nine months if taken care. It can be dyed up to a medium blonde color.
7A GRADE-7A is of good quality; generally, the hair is from two donors and is single drawn. The quality and texture from two different donors are tried to maintain perfectly. It is a 100% human Remy hair with a strong hair shaft. It has a full cuticle that can be dyed up to a platinum blonde color.
8A GRADE-8A is one of my favorites, although a bit expensive, but well worth the cost because of quality. It is very high quality 100% human hair with a very strong hair shaft and full cuticle. This is from a single donor. With proper care, it can last up to two years. It can be dyed up to white color.
9A GRADE-There is a slight difference between 8A and 9A. All the quality standards are the same as 8A. The only difference is that the hair quality is better or I must say that it is best in the market nowadays. At last, I will like to conclude that the current grading system ranges from company to company.
One companies version of 8A hair may not be the same as another, as there is no regulating body that controls what can be considered 6A, 7A, 8A, 9A or 10A hair. Always go according to your needs.
