More than 25 years ago, Great Lengths established itself as the premier producer of high-quality extensions and started a new era in the professional beauty industry and the mainstreaming of hair extension services.

Today, Great Lengths can be found in salons in more than 50 countries and the Great Lengths Certified Salon Network remains the most exclusive stylist membership in the industry.

Thermal 3200

The original and still unrivaled Great Lengths Thermal 3200 application machine.


Producing results simply not possible with any other system, the Great Lengths 3200 applicator tong is heated on one side. The temperature, which is approximately the same temperature as the lowest setting on a standard curling iron, is used to soften the Great Lengths bond so it can be molded to your natural hair. Unlike other systems, where glue guns and wax melting pots are used, the 3200 applicator allows for a very clean and precise application. The result is undetectable attachments that are brushable, durable and non-damaging.

Ultrasonic 5000 Cold Fusion

The Next Level in hair extension application technology.


Whereas the original Great Lengths 3200 Thermal method utilizes heat to soften the bond so the bond can be molded around the group of natural strands that the bond is attaching to, the Ultrasonic 5000 Cold Fusion method utilizes ultrasonic wave. This wave or “vibration” action generates heat within the bond and this allows the bond to surround each individual strand within the group of natural strands the bond is being attached to. This added bonding security allows the stylist to mold the bond attachments into “flat” bond formation without compromising the bond “seal” to the client’s hair. Of course, traditional “round” bond formations with the Ultrasonic 5000 are possible too. This gives the stylist more application options to truly customize their Great Lengths Services to each client’s specific need and desired result.


GL Apps by Great Lengths

GL Apps by Great Lengths is a double-sided, single tab tape-in extension system. Using the same virgin quality hair Great Lengths is known for, GL Apps give stylists the opportunity to introduce extension services to a broader client base with lower application price points and less application time commitment, all without compromising the quality of the hair used or the resiliency of the application. The attachment site is securely sandwiched between fine layers of the client’s natural hair, resulting in the most undetectable attachment of any tape system on the market. GL Apps are a high speed connection application system and as any good app will do, they make getting extensions easier, faster and more accessible.

100% Indian Temple Hair. Ethically sourced and traceable, guaranteed.


It has been estimated that of the 1000 tons of human hair shipped into the US every year, only 25% is from known ethical sources. With no current regulatory body demanding ethicality in the hair extension industry, the salon industry, and the consumer has had no guarantee that the hair extensions they chose were traceable, ethical or of good quality – until now.


Great Lengths sources the very best human hair from Indian Hindu Temples. The hair has been donated willingly by villagers to the temple as an act of devotion to their faith. The revenue generated by Temple Hair is used for the funding of schools, health clinics, and other community services.

The Setting Fair Standards Seal guarantees that Great Lengths hair extensions have met the following criteria:

-Every strand has been donated willingly and with the full consent of the donor.

-The donor has been treated with respect and care.

-A fair and reasonable price is agreed for the hair and the money used to procure the hair is used solely for charitable endeavors, not for personal or individual profit.

-A company representative has procured the hair to cut out unreliable middlemen and ensure full and direct knowledge of the origin of the hair.

-Exclusive in-house production processes are used from procurement of the hair to wholesale selling to ensure full traceability.

-Great Lengths hopes that the Setting Fair Standards Seal will pave the way to unified ethical regulation of the hair extensions industry.

In 1992, Great Lengths International developed and patented the first pre-tipped, synthesized keratin bond polymer. Because of this ground breaking technology, many extension companies now claim a “keratin bond” as their form of attachment. Any form of keratin can be combined with any type of polymer to qualify as a “keratin bond,” regardless if it makes any functional difference in the bond itself. Unfortunately “keratin bond” has become more a marketing term than a functional benefit. The GL Synthesized Keratin Bond molecular structure is specifically designed to mimic the molecular structure of human hair.


The result gives the GL bond functionality that is not available in any other hair bonding compound in the marketplace. The GL bond has the ability to expand and contract mimicking the human hair it’s bonded to. For example, when hair gets wet, the hair shaft expands. When it dries, it contracts. Bonds that do not possess such function will soon begin to shed the extensions and ultimately slide off the client’s natural hair completely because the bond is being stretched with no capacity to contract each time the client’s natural hair expands and contracts. This is a Great Lengths exclusive feature.

The Color

The only process performed on Great Lengths hair is our colorization process. Great Lengths does not use any toxic chemicals (i.e. ammonia and/or bleach derivatives) in the de-pigmentation and pigmentation process of our hair. The result is colorfast hair that has not been subjected to damaging ammonia and/or bleach chemicals to remove the hair's original color.


Additionally, the benefit of this GL patented process goes beyond the Great Lengths hair quality; there is no negative Eco impact from our production process. This point becomes magnified when compared to the significant negative Eco impact created by all hair processing facilities, of which the overwhelming majority are located in China and Indonesia where there are no effective regulatory agencies to monitor such production.
