Since hair extensions have become increasingly popular over the years and the market is getting bigger with all kinds of extensions, hair suppliers have developed a hair grading system to determine the quality of the hair.<\/p>\n<p>Not all hair is high-quality and for the high-class market. Some hair is low-quality and low-priced. These extensions are usually sold in the lower-class market, and there is nothing wrong with that. What do you do to specify hair quality? Invent a system! Below, we will explain all the differences in simple and easy-to-understand terms.<\/p>\n<p>It\u2019s now much easier to tell whether the hair is high, medium, or low. For example, you\u2019ve got 5A, 6A, 8A, or even 10A hair, and that number determines the quality of your extensions.<\/p>\n<div class=\"td_smart_list_2 td-2-columns \">\n<div class=td-item>\n<div class=td-number-and-title>\n<h2><span class=td-sml-current-item-nr>1 <\/span><span class=td-sml-current-item-title>The Difference Between Hair Grades<\/span><\/h2>\n<\/div>\n<\/div>\n<\/div>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-16741 lazyload\" title=\"AiryHair Tape in Hair\" data-src=\"https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions.jpg\" alt=\"AiryHair Tape in Hair\" width=\"1200\" height=\"450\" data-srcset=\"https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions.jpg 1200w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions-745x279.jpg 745w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions-1024x384.jpg 1024w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions-696x261.jpg 696w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions-1068x401.jpg 1068w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions-1120x420.jpg 1120w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/tapein-extensions-150x56.jpg 150w\" data-sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1200px; --smush-placeholder-aspect-ratio: 1200\/450;\" \/><\/p>\n<p>That sounds pretty simple, but there is a lot of confusion regarding the hair grading system! Let\u2019s get down to some of the more important aspects first.<\/p>\n<ul>\n<li>The grading system has changed over the years. What was once considered high-quality hair a couple of years ago (5A) has become medium-quality.<\/li>\n<li>Many hair companies are not honest about hair quality. They will use top hair grades to sell you low-quality hair for a high price.<\/li>\n<li> No one regulates the grading system. You can mark synthetic hair as 10A and sell it. However, it would help if you still had a basic understanding of the whole thing. To avoid confusion and save some money in the long run.<\/li>\n<li>It\u2019s also important to learn about the different types of hair extensions. This ensures that you know exactly what is going to come with your order.<\/li>\n<li>Just like sheets with thousands of threads, these numbers are less relevant nowadays. Anything above 250 is a marketing sham, as proven by scientific studies.<\/li>\n<\/ul>\n<h3>Hair Extension Types<\/h3>\n<p>Let\u2019s quickly go over the most important <a href=\"https:\/\/www.airyhair.com\/blog\/comparing-hair-extensions-types-virgin-hair-vs-remy-human-hair\/\"><strong>hair extension types<\/strong><\/a>. There is 100% virgin hair, Remy hair, 100% human hair, human hair quality, and synthetic hair.<\/p>\n<h4>100% Virgin Hair<\/h4>\n<p>This is the most expensive hair you can buy, and it is of the highest quality. It is human hair with all the cuticles going in the same direction, and it hasn\u2019t undergone any chemical or mechanical processing.<\/p>\n<h4>Remy Hair<\/h4>\n<p>Remy&#8217;s hair is also 100% human hair, with all the cuticles going in the same direction, but it has been chemically or mechanically processed. It is also high-quality hair that will last you for a long time.<\/p>\n<h4>100% Human Hair<\/h4>\n<p>100% human hair has not been mixed with synthetic hair, but it has been stripped of its cuticles and might be chemically processed. It will not last as long as 100% virgin or Remy&#8217;s hair.<\/p>\n<h4>Synthetic Hair<\/h4>\n<p>Synthetic hair is made from no human hair whatsoever. It\u2019s completely synthetic, and it would be considered low-quality hair that won\u2019t last a long time.<\/p>\n<div class=\"td_smart_list_2 td-2-columns \">\n<div class=td-item>\n<div class=td-number-and-title>\n<h2><span class=td-sml-current-item-nr>2 <\/span><span class=td-sml-current-item-title>Grade 3A<\/span><\/h2>\n<\/div>\n<\/div>\n<\/div>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-16754 lazyload\" title=\"Grade 3A Hair Extensions\" data-src=\"https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair.jpg\" alt=\"Grade 3A Hair Extensions\" width=\"1200\" height=\"450\" data-srcset=\"https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair.jpg 1200w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair-745x279.jpg 745w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair-1024x384.jpg 1024w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair-696x261.jpg 696w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair-1068x401.jpg 1068w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair-1120x420.jpg 1120w, https:\/\/www.airyhair.com\/blog\/wp-content\/uploads\/2017\/09\/grade-3a-hair-150x56.jpg 150w\" data-sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1200px; --smush-placeholder-aspect-ratio: 1200\/450;\" \/><\/p>\n<p>This is low-quality, very thin hair that was not properly maintained by the donor.
