5 Best Sew In Hair Extensions Reviewed
Now I will go through my top picks for the best sew in hair extensions and explain the key features for each one.
- Key features: 12A grade 100% unprocessed Brazilian virgin hair, double machine weft, 300g bundles
- Volume: 3.5 oz
- Hair Length: From 8-32 inches
- Best for: Overall
With this hair, you are getting 100% unprocessed virgin hair cut from one donor. This ensures that all the cuticles are intact and also that the hair can be permed, straightened, curled, or dyed.
You are getting high-quality and natural looking extensions that don’t shed or tangle. The double machine weft gives you a full look with 100g of volume for each bundle. With these extensions, you are guaranteed fullness and thickness from roots to ends.
This hair is soft and shiny and doesn’t have flyaways or short pieces of hair sticking out like other extensions do. You can use these extensions multiple times for your installs.
Although you can color and bleach this hair, please note that the quality can change somewhat and won’t remain the same afterwards. For this reason, I would suggest trying different extensions.
- Key features: 9A grade 100% unprocessed Brazilian virgin hair, true to length, true to weight
- Volume: 9.45 oz
- Hair Length: From 8-28 inches
- Best for: Straight
These are the best silky straight extensions that will give your sew in that sleek look if you are looking for bone straight. This hair is 9A unprocessed Brazilian straight human hair, making it durable, reusable, and easy to style.
The exquisite workmanship showcases a reinforced double weft that makes the extensions durable with little to no shedding. These extensions can last up to one year with the proper maintenance and care.
You don’t have to worry about split ends because this hair is cut from young and healthy donors. The ends are thick and there is fullness throughout, making this hair true to length and weight.
The only downside to these hair extensions is that there is some tangling, and it can become matted and dry. You will probably need to give them more love and care than other options. I would recommend trying different extensions for this reason.
- Key features: 10A grade Brazilian virgin hair, double machine weft, high elasticity
- Volume: 11.5 oz
- Hair Length: From 10-24 inches
- Best for: Curly
These curly hair extensions will give you a natural and defined look that can last up to a year with the proper care. Its 10A grade Brazilian hair can be dyed, bleached, and straightened without the worries of shedding and tangling.
These curls are bouncy and soft, with high elasticity that will return to its original state after manipulation. If you have 3a-3c hair, then these extensions will blend in with your natural hair, making it look like it is coming from your own scalp.
The double machine weft ensures that this hair is full and has thickness throughout, no matter the length. Just use your favorite curling cream to keep this hair looking defined, tamed, and moisturized.
The only downside to this hair is the process of detangling it. You will need patience and a wide-tooth comb to properly detangle this hair. If you don’t have time to maintain this hair, then I recommend trying out other extensions.
- Key features: 9A grade Brazilian virgin hair, four bundles, true to length
- Volume: 1 lbs

- Best for: Affordable
You don’t have to spend an arm and a leg to buy quality extensions these days. The Coisini body wave hair extensions are made with 9A grade Brazilian virgin hair, making it suitable for restyling with no tangling or shedding.
You get four bundles with this hair from 14 inches to 20, giving you a reasonable length at a reasonable price. This hair is soft and shiny and will maintain its body waves even after you wash it.
The reinforced weft makes these extensions full and thick throughout from root to tips. There is no chemical processing, or any chemical smells with this hair.
This hair is great for the price if you’re on a tight budget. However, after wearing this hair for a few weeks, it can become rough and matted. I wouldn’t recommend this hair for long-term use.
- Key features: Brazilian Remy hair, double weft, straight
- Volume: 7.2 oz
- Hair Length: From 10-24 inches
- Best for: Balayage
This Brazilian Remy hair is durable, thick, soft, and blends well with many hair textures. It is a double weft that makes it fuller but doesn’t have any shedding.
The hair can be dyed, curled, and styled as your own hair. It is super soft and comes in various colors to match different hair types.
Just note that while the hair can be dyed to the darker colors, it can not be bleached.
This hair is beautiful for those interested in color and balayage, but the hair does tangle after two weeks. For this reason, I would recommend trying other extensions.
Best Sew In Hair Extensions – What to Consider?
Take into account the following factor before you hit the purchase button.
When it comes to hair extensions and looking for the best options, then hair quality should be on the top of your list. Having good quality hair can make such a huge difference when it comes to buying sew in hair extensions.
Not all human hair is treated equally and if you want your sew in hair extensions to treat you right, then I suggest you go for unprocessed human hair. Unprocessed human hair, or virgin hair, is a high quality grade of hair that will last and give you the most options when it comes to your sew in hair extensions.
Virgin hair can be dyed, straightened, curled, bleached, or permed, as you like. Another wonderful thing about virgin hair is that you can reuse it again and again. This will come in handy if you wear extensions often.
Taking proper care of your hair extensions is half the battle and just as important whether you’re wearing them in your head or not. Maintenance can have your extensions looking fresh and healthy even when they are old.
Investing in a really good shampoo and conditioner can be just the fix you need to having lovely extensions all year round. Additional treatment options should be considered for coarser hair textures, like a deep conditioner.
Having a detangling comb and brush is also very useful for removing knots and grooming your extensions properly.
The great thing about sew in hair extensions is that they come in various lengths, making them popular and comfortable for different people to wear them. Picking out the perfect lengths can be helpful in making your decision.
The longer the hair, usually the thinner the bundle. This might not be the case for all vendors, but it can be true to some. If you are looking for longer lengths, just be wary that you might not get the same fullness as shorter or standard lengths.
Make sure to check the reviews if you are unsure about the length you may be interested in. It’s always a good idea to message the seller when in doubt about any concerns you have about the hair.
Having the right hair extensions for your sew ins can make your installs go from flat to all that. My top pick is QTHAIR 12A Grade Brazilian Virgin Hair Body Wave because of its premium hair quality, styling versatility, and fullness throughout because of the double machine weft. You will enjoy bouncy and shiny hair with these extensions no matter the season.
