Genius Weft Extensions
When it comes to hair extensions, we've applied, and personally worn, just about every make and model out there. You may wonder, with options like Tape Ins and Keratin bonded - a few of our absolute faves - if there is room in our hearts for hand tied hair extensions! Hand sewn wefts certainly have their advantages.
For what it's worth, here's how we feel about them and why. Hope you find this helpful!
-The Siren Stylists
We love the lightweight volume and flexibility of today's weft extensions.
Weft extensions have evolved from hand tied wefts into what we today call the genius weft or envy weft. They are flexible and lightweight and because they don't have a strip return hair, they are much more comfortable to wear. And because they have a polymer top, we can cut them to size without them unraveling, making them very easy to customize.
Genius Weft Extensions are the lightest hair extensions!
People use the term "hand tied" differently in the extensions industry, so let us clarify. The hand tied extensions I offer use hand-finished wefts, as well as machine finished wefts, and they attach to the hair using a one of our variations on the beaded row technique. It's the hand-finishing along with the sew in application make these extensions super lightweight! More about the application in a moment.
Brands We Use:
We use Siren Signature Extensions, our own line of human hair wefts.They are available in lengths of 16 to 24 inches. Extended lengths can be special ordered.
Envy Wefts/Genius Wefts, an even lighter and slimmer weft for hand tied extensions. They are very discreet and comfortable. What's cool about the Envy Wefts is that they don't have a moustache - those short hairs at the top of the band. This makes them even more comfortable, and allows us to trim the band to split it into smaller wefts without any fraying or shedding of hairs.
We also use Coco Marie Hair Extensions, a brand of human hair weft extensions from Denver, Colorado. They are available in lengths up to 28 inches in a beautiful color palette of pre-colored shades. They're made of European hair which is a great match for those with a similar soft hair texture.
To Color or Not to Color?
We customize by matching your hair and desired color to the palette of pre-colored shades (which includes naturals, blondes, rooted shades and balayage) or can custom color the extensions if necessary.
Brands of Genius Weft Extensions
Siren Signature Extensions
We use our own line of hair, made with 100% human Remy hair and available in 16", 18", 20" and 24" inch wefts. These are great volumizing option for those with fine hair who are candidates for hand tied extensions. Because they are ultra light and slimmer than other hand tied wefts, Envy Wefts are even more discreet and comfortable. What's cool about the Envy Wefts is that they don't have a moustache - those short hairs at the top of the band. This makes them even more comfortable - no pokey hairs - and allows us to trim the band to split it into smaller wefts without any fraying or shedding of hairs. They lay flat against the head so you get volume without bulk. They are also longer lasting.
Coco Marie Weft Extensions
We love this hair extensions brand from Colorado called Coco Marie. They are made with 100% human Remy hair and come in lengths up to 28". The hair is European making it a perfect match for our clients with straight, finer hair. The quality is fantastic and they have a beautiful palette of pre-colored shades. With Coco Marie Wefts you'll get 8-9 months of total wear.
Wefts Installation
First we create a row of beads using string then we attach wefts of hair to the beads using a needle and thread.
Let's look closer at install time. After all, this is one of the main factors that influences the cost of the service. Installation time for hand tied weft extensions is pretty efficient, more so than you might think. It takes about 45 minutes per row for an accomplished extensions artist, that’s a whole head in 1.5 to 2 hours.
Compare the time it takes to install a full head of hair extensions.
| Type | Installation Time |
| Tape Ins | 1 to 2 hours |
| Fusions | 4 hours + |
| Hand Tied Wefts | 1.5 to 2 hours |
How to spot the perfect weft installation?
Well, it should look like this picture.
- Thread should match the natural hair color
- Hair should match at the root where the attachments are - this helps conceal them
- Wefts should be flat, no folds or bunching
- Hair should look smooth, no snarls
- Neat and tidy!
Minimal points of contact, wefts close and flat to the scalp, these are key for a natural look.
They work for everyone.
Before deciding the best type of extensions for a client, I consider all factors. Hair thickness, lifestyle... even factors like dry vs oily. Hair that tends to be oily can make adhesives tacky over time which are painful to remove or cause bonds to slip. Excess scalp oil or even moisture is not an issue when wearing hand tied wefts. We can count on the hand tied method here because they’re attached with a strong nylon thread and a silicone bead that won’t slip or become tacky when exposed to moisture.
Hand tied extensions can work for most hair density, from thick to thin. Although tape ins are extremely delicate and gentle on fine hair, the weigh distribution and minimal points of contact make hand tied extensions a great option for thin hair. Extensions that are packed with hair like these make wefts a great option for clients with thick hair too! Clients don’t have to spend as much time in the chair as with other methods since you can add more hair at one time with wefts!
A good match for an active lifestyle.
If you're like us, you stay active and don't want to worry about hurting your extensions. If you frequently wet or wash your hair, hand tied extensions are up for the task. If you work out or prefer to wash your hair every morning, then hair tied extensions are a good match for you. With hand tied extensions, you don’t have to worry about any bonds. With tape ins, the adhesive can weaken with excessive washing, and with fusions, the keratin bonds can swell and break down with excessive moisture. So for active ladies, we recommend hand tied extensions.
They are invisible.
One concern our clients raise is about bond visibility. As a professional stylists, of course our goal with any method is to make the attachments as invisible as possible! But when it comes to invisibility, we have to give credit where credit is due. Hand tied wefts are never bulky and we can position them close to the scalp. And because they lay so flat against the head, they mimic your natural hair more than other types of extensions. Hand tied wefts literally look as if they were growing out of your own head! Our clients who wear hair extensions can wear their hair up in a pony tail, in a bun or even parted down the middle with two braids.
We can really customize your color.
We customize your hand tied extensions in one of two ways, or a combination of both. We can match your hair and desired color to palette of 23 pre-colored shades (which includes naturals, blondes, rooted shades and balayage) or we can color the extensions if necessary before we install them. After all, they are made of top quality 100% Remy human hair, so they can be dyed and highlighted just like your natural hair.
Extended total wear time.
You can get 6 months of wear out of them. They need to be removed and resewn into place every 6 weeks or so, but they are low maintenance and great for the active woman. Here's how they compare to other types of hair extensions.
| Type of Extensions | Typical Wear Time |
| Tape in Extensions | 6 months |
| Fusion Extensions | 3-4 months |
| Hand Tied Wefts | 6 months+ |
| Coco Marie Wefts | 8-9 months! |
They cost less than you think!
How much do hand tied hair extensions cost? The cost will depend on how much hair you require, if the extensions need to be custom colored before they are installed, and if your desired look requires overall color or highlights before installation. It's impossible to quote an amount as the cost truly varies from person to person. What we can say for certain is that hand tied hair extensions are a happy medium, a middle ground on the cost spectrum. Similar to the cost of tape in extensions, hand tied wefts fall between clip ins/halo extensions and fusion extensions.
This will give you an idea of where hand tied extensions fall on the cost spectrum.
| Type | Cost for Full Head |
| Clip Ins | $$ |
| Tape Ins | $$$ |
| Hand Tied Wefts | $$$ |
| Keratin Bonds | $$$$ |

Frequently Asked Questions About Weft Extensions
What is the difference between Genius Wefts and Keratin Bonds
«Genius wefts are applied in rows using a beaded foundation and are ideal for adding volume and length quickly.
Keratin bonds are applied strand by strand using a thermal fusion method and offer the most natural movement and flexibility.
We’ll recommend the best option based on your hair type and goals.
What are genius weft hair extensions?
«Genius weft extensions are an ultra-thin, flexible style of weft extension designed to lay flat against the scalp for a more comfortable, natural-looking result. Unlike older bulky wefts, genius wefts can be cut and sized without unraveling and have no irritating return hairs or “moustache,” making them ideal for discreet wear.
Are genius wefts the same as hand tied wefts?
«Not exactly. Many people use the term “hand tied” to describe the installation method rather than the actual hair itself. At Siren, we use a beaded row application combined with lightweight wefts such as genius wefts and other hand-finished wefts to create a comfortable, natural result.
How long will my weft extensions last?
«The hair itself can last 6 months or longer with proper care, depending on the brand and how well they are maintained. Some premium wefts, such as Coco Marie, may last 8–9 months. Your rows typically need to be moved up every 6–8 weeks as your natural hair grows.
Can I wear my hair in a ponytail with weft extensions?
«Yes. One of the advantages of modern genius wefts is how flat and discreet they are. When properly installed, most clients can comfortably wear ponytails, buns, braids, and other upstyles without visible attachments.
Are weft extensions good for thin hair?
«They can be. Modern lightweight wefts are often a great option for clients with fine or thinner hair because they distribute weight evenly and avoid bulky attachment points. During your consultation, we’ll determine whether wefts, tape-ins, or another method is the best fit for your hair density.
