When buying human hair wigs or extensions, you often see virgin hair or Remy hair being titled as 10A, 8A, 7A, etc. What does that hair grades mean? What is the difference between 4A, 5A, 6A, 7A, 8A, 9A, 10A virgin hair? In the following article, we will help you learn the human hair grading system.

Human Hair Market & Hair Hair Grading System

To collect the donor's hair, it is tied in a ponytail and then cut. In this way, the scales all keep the same direction, to avoid the formation of knots, breakage and ensure good resistance over time. The hair is then washed and disinfected by gentle methods, then tied in locks or mounted in strips, by hand or by machine. This is how human hair extensions are made. 

What Is Human Hair Grades - 10A, 8A, 7A, 6A, 5A?

With the development of hair extension technology in recent years, more and more beautiful women are in love with hair extensions that can create elegant and natural hairstyles quickly and lastingly. But not all human hair products can achieve the desired effect and duration of the receiver. Not all human hair products on the market have the same quality and longevity, so some extensions must be put on the extension because it makes it easier for women to make choices when looking for new hair. Factories and manufacturers define the level of hair products based on the different types of hair used when making hair extensions or braiding. This hair quality type navigation feature can help hairdressers navigate and speed up work when installing hair in salons, and also make it easier for consumers to make accurate choices based on demand when buying,

Depending on the donor's age and the health of her hair, the locks are then classified into categories. You read on the labels 4A, 5A, and even 6A and 7A ... In principle, just like on the stock exchange where companies track the triple-A, the higher the score, the better the quality (6A = hair of a young woman 18-year-old who has never been sick, has used since birth only sulfate-free shampoos and never styling based on silicone or electric dryer. B+ hair, it would be the hair of his grandma, a little tired and asthmatic. In reality, the situation is quite different. This hair gradation, which seems satisfactory from a theoretical point of view does not, in fact, meet any standard, even no confirmed standard. There is no regulatory body, so each wig & hair supplier is going over the top. 

Human Hair Grades - Differences & Lasting Time of 10A, 8A, 7A, 6A, 5A, 4A Hair

But the following definitions are widely recognized in the current hair market, establishing a classification in view of the ability of the hair to withstand more or less extreme chemical discoloration! We will tell you what is each grade of hair exactly and how long it lasts. 

• Grade 10A Hair: It is 100% unprocessed virgin hair from one donor with thick ends and strong structure, a good choice for #1B color, curly hair owners. Can be dyed up to platinum white without much damage, and still remain healthy-looking, sleek and shiny. Such as the 10A virgin hair on Justvirginhair.Com can last for over 2 years under properly caring.

• Grade 8A (9A) Hair: It is 100% unprocessed Virgin Hair bundles from one donor, all with intact cuticles, and mixed with fewer short hairs. Can be dyed up to white, but once you dyed or curled, it won’t be virgin hair anymore and would short its lifespan. 8A hair can expect to last for 2 years with correct maintenance.

• Grade 7A+ Hair: It is the same quality as the 7A hair, but very slightly short hair in the bundles.

• Grade 7A Hair: It’s from a single donor, with cuticles aligned, and never having been treated chemically. Can be colored up to color 613 (platinum blonde). 7A hair can expect to last for 18 months.

• Grade 6A+ Hair: It is 100% Remy hair and thicker than 6A below, this means that 6A has more short hair mixed in the bundle. 6A hair can expect to last for 1 year.

• Grade 6A Hair: It is usually referred to as Remy hair without adding any animal or synthetic hair, can be dyed up to color 27 (blond or brown). 6A hair can last for up to 10 months.

• Grade 5A Hair: It is 100% human hair (Non-Remy hair) without adding any animal or synthetic hair, can be dyed up to color 6 (light brown). 5A hair usually lasts for a couple of months.

• Grade 4A Hair: It is Non-Remy hair without adding any animal or synthetic hair, suitable for the lower class market, can be dyed up to color 6 (light brown). 4A hair usually lasts for a couple of months, shorter life than 5A.

• Grade 3A Hair: It is a kind of brittle and blendable fine hair, either chemically colored or bleached. It is the cheapest human hair but could be tangled, shed even end up with split ends, so you only can expect it last for fewer months.

Suffice to say that there is no 100% reliability in this grade, supposed to allow selection on rigorous criteria. Remember that by definition, virgin hair comes from a single donor. In the example above, only grade 7A is actually virgin hair. In fact, at Justvirginhair.Com, we don’t use these terms much, it’s not so necessary for us to use these terms because we only sell 100% unprocessed virgin hair bundles with the highest quality, you can say it is Grade 10A hair!
