Siren Signature Extensions by Caitlin Essing
Premium Hair. Signature Results. Developed for the specific techniques, standards, and results we deliver in the salon every day.
This is not off-the-shelf hair. Every detail from the construction to the color palette has been selected to create seamless blends, long-lasting wear, and the most beautiful, natural-looking results.
Currently available in both Genius Wefts and Keratin Bonds, this line allows us to customize each installation based on your hair type, lifestyle, and goals.
Multiple Application Methods. One Standard of Quality.
Luxury You Can Feel
Siren Signature Hair is made from 100% human hair of the highest quality, selected for softness, longevity, and consistency.
- Silky, natural straight texture
- 60 grams per weft (more than other leading brands)
- Colored using textile dyes which means less fade, less oxidation. Color lasts longer and stays truer to the original shade.
- Never mass produced
Wavy textures will be available soon, expanding options for even more natural blending.


Genius Wefts with Beaded Row Application
Our Siren Seamless Extensions are designed for clients who want fullness, length, and a flexible, comfortable wear.
These ultra-thin wefts lay flat against the head and move naturally with your hair, making them ideal for both everyday wear and dramatic transformations. Siren Signature Wefts last longer. Brunette hair lasts up to 1 year, blondes up to 9 months, or longer with better care.
What sets them apart:
- Flexible, cut-to-fit wefts for precise customization
- No return hairs, no “mustache,” and no scalp irritation
- Lightweight and comfortable, even with longer lengths
- Ideal for adding both volume and significant length
Available lengths: 16, 18, 20, 22, 24 inches
Custom length available: 26 inches

Keratin Bond Extensions
Keratin bond extensions are the most discreet and natural-looking option for clients who want movement, versatility, and maximum invisibility.
Each strand is individually applied using a keratin bond and thermal fusion tool, allowing for complete customization throughout the head. Siren Signature K-tips last from 3-5 months with proper care.
Why clients choose bonds:
- 360-degree movement and styling freedom
- Seamless integration, even in finer or thinner areas
- No rows or tracks
- Ideal for detailed, highly customized placements
Available lengths: 18 and 22 inches

A Color Palette Designed for Real Hair
One of the biggest advantages of Siren Signature Hair Extensions is the color palette. We’ve built this line around how real hair actually looks and around the colors that are in demand.
You’ll find:
- Pre-blended dimensional shades
- Pre-blended rooted shades
- Pre-blended balayage shades
- Classic solid shades
Because many shades are pre-blended, there’s often no need to mix multiple colors before your installation. That's one of our favorite features about this line - less custom color work. This allows for faster applications and more natural, lived-in results. And because Siren Signature Hair is colored with textile dyes, there is less fade and color stays true to its hue.

Frequently Asked Questions About Siren Signature Hair Extensions
What makes Siren Signature Hair Extensions different from other brands?
«Siren Signature Hair Extensions were developed with a focus on quality, longevity, and real-world performance behind the chair.
Here’s what sets them apart:
Not mass produced
The hair is carefully sourced and processed in smaller batches, which helps maintain cuticle integrity and overall consistency. This results in hair that feels better, behaves more naturally, and lasts longer.
Higher density wefts
Our genius wefts offer approximately 60 grams of hair per weft, providing fuller coverage with fewer rows. This allows for a more efficient installation and a more balanced, natural result.
Longer-lasting quality
Because of the way the hair is selected and processed, it maintains softness and strength over time. Clients typically experience longer wear compared to standard extension hair.
Advanced color technology
The color is achieved using textile dyes, which helps prevent fading and oxidation. This means the tone stays truer for longer, especially important for blondes and dimensional shades.
Dimensional, ready-to-use shades
Many colors are pre-blended, so we can achieve a natural, multi-tonal look without having to mix multiple wefts before installation. That means less custom color work.
Highest grade human hair
All Siren Signature Hair is made from premium, 100% human hair, selected for its quality, consistency, and performance.
Many lower-cost extensions are heavily processed or silicone-coated to feel soft at first, but quickly lose that quality with wear. Siren Signature Hair is designed to maintain its look and feel over time with proper care.
How long do Siren Signature Hair Extensions last?
«Siren Seamless Extensions (genius wefts):
These are designed to last longer than many mass-produced options on the market.
- Brunette shades can often last a year or longer
- Blonde shades typically last 9 months or longer with proper care
Because the hair is not mass produced and maintains better cuticle integrity, it stays softer, stronger, and more consistent over time.
Keratin Bond Extensions (K-tips):
- Typically last 3 to 5 months with proper care
These are a more temporary, strand-by-strand option and are replaced rather than reused.
Your at-home care routine, heat styling habits, and maintenance schedule all play a role in how long your hair lasts. We’ll guide you on exactly how to care for your extensions so you get the most out of your investment.
How does the cost of Siren Signature Hair Extensions compare to other premium brands?
«The investment will vary based on the method, length, and amount of hair needed to achieve your desired result.
In general:
- Keratin bond extensions (K-tips) are priced below Great Lengths while still offering high-end quality and performance.
- Siren Seamless Extensions (genius wefts) are comparable to other premium weft options on the market.
Pricing isn’t just about the hair itself. It also reflects the overall time required to achieve the result.
Because Siren Signature Hair is designed to last longer and maintain its quality over time, many clients find it offers strong value when compared to lower-cost options that need to be replaced more frequently.
A consultation allows us to give you a clear, personalized quote based on your goals.
How long does it take to order Siren Signature Hair Extensions if my color or length isn’t in stock?
«Turnaround time for Siren Signature Hair Extensions is typically very fast compared to many other brands.
Because the hair is already stocked in the U.S. (with a warehouse based in Texas), we’re able to receive most custom orders quickly without the long delays often associated with international shipping.
This also means:
- Consistent, reliable delivery times
- No unexpected delays due to customs, tariffs, or duties
- Stable pricing without fluctuation from import costs
In most cases, your hair can be ordered and ready for your appointment within just a few days.
We’ll confirm timing during your consultation so you know exactly what to expect.
