Great Lengths stands apart because of its commitment to both quality and ethics. Their hair is 100% ethically sourced, ensuring full traceability and respect for the communities involved. Great Lengths is also a certified B-Corp, which means they meet high standards of social and environmental responsibility, transparency, and accountability.

In addition, Great Lengths holds a patent for their keratin bonds, and their application machines are uniquely designed to protect the integrity of your natural hair during every service. This combination of ethical practices, innovation, and care makes Great Lengths one of the most trusted luxury extension brands in the world.

Hair extensions are a cosmetic procedure and should only be applied to healthy hair. Hair must be at least 5cm in length, though ideally 8cm or longer to ensure comfortable and discreet attachments. There are some medical conditions that may make a minority of clients unsuitable for extensions. Suitability is discussed during a consultation with a Great Lengths Certified Stylist – these are always free and no-obligation.

Extension pricing varies depending on your hair goals, the method used, and how much hair is needed. Here’s a general idea of what to expect:

• Volume Sets: $400 – $900+
  Perfect for clients who love their length but want more fullness and density.

• Lengthening Sets: $1,500 – $3,000+
  Designed for clients who want to add significant length as well as volume.

Because every head of hair is different, the exact price will be determined during your consultation. This ensures we select the right method, length, and amount of hair to achieve your desired look while keeping your natural hair healthy.

A consultation is the most important first step in your extension journey. During this time, we’ll carefully look at your hair and talk through your goals so we can determine the best method, length, color, and amount of hair for you. This ensures that your extensions not only look beautiful but are also safe for the health of your natural hair and last as long as possible.

Because extension hair is custom-ordered for each client, we don’t keep a large stock in the salon. The consultation allows us to place the perfect order tailored just for you, so everything is ready when it’s time for your application.

Think of it as building the foundation. With a proper consultation, you can feel confident your extensions will blend seamlessly, feel comfortable, and give you the longest wear possible.

For a deeper look into why this step matters so much, watch our video below.

Many extension brands advertise “K-Tips,” but in most cases these are made with glue or silicone polymers—not true keratin.

Great Lengths Keratin Fusion is different. It uses the only true keratin bond on the market, backed by patented Great Lengths technology. This bond is designed to mimic the natural structure of your own hair, allowing it to expand and contract as your hair gets wet and dries. The result is a more natural feel, greater comfort, and healthier, longer-lasting wear.

In short: K-Tips are typically glue or silicone, while Great Lengths offers the only patented keratin technology—created specifically to protect your hair and deliver the best results.

You can be assured that Great Lengths’ Pre-Bonded and Tapes have been scientifically proven not to cause damage to healthy hair when applied correctly and maintained properly. The key to a successful, damage free application lies in the details of the application. There is no “cookie-cutter”, “one size fits all” application technique, as each client has different hair conditions and desired results that must be considered. The skill level of the stylist is crucial for a damage-free application and this is why Great Lengths Certified Stylists are the most sought after by extension clients worldwide.

No, your stylist can apply as few extensions as you need to achieve the look you want. Hair extensions can also just be applied to a specific area, such as at the sides. The possibilities are endless.

Timing depends on the method chosen and your current vs. desired density and length. Timing for extensions can range from 60 minutes to 9 hours. During the consultation, your stylist will be able to advise you on estimated application time.

Great Lengths Pre-bonded can last up to 6 months if well maintained and depending upon the type of application performed (i.e. lengthening, volumizing, etc.). GL Tapes last about 4 – 6 weeks but can be re-used up to three time.
Both removal timeframes are dependent upon the state/condition of the client's natural hair and their lifestyle.

Great Lengths Service cost can vary greatly from client to client because each is truly a custom service. There are also many GL application options to be considered, such as lengthening, full volumizing, zonal volumizing, dimensional color work or special needs applications.
During the consultation with your stylist you will receive the most accurate answer, based upon the state of your natural hair and desired result.

Great Lengths extensions are made from the finest human hair because it behaves like your own hair and offers a more natural look. This means that our hair extensions can be treated in just the same way as your own hair: can be styled using heated tools, as well as professionally coloured and permed. They are also suitable for most lifestyle activities including swimming.

The term “Remy” defines hair that, within the same strand, is all in the same direction from the roots to the ends. All Great Lengths hair is classed as Remy. The main benefits are that the hair is easier to maintain, less likely to knot and blends well.

The most important rule of hair extension maintenance is brushing. Regardless of the brand or method, daily brushing is essential to prevent tangling or matting. We naturally shed over 100 hairs a day, and with extensions those shed hairs become trapped at the attachment points. If they aren’t brushed downward, they can build up and cause matting or damage.

Because all Great Lengths hair extensions are made from the finest human hair, your care routine will be very similar to caring for your own natural hair. The key differences are:

• You may need to wash your hair less frequently.

• Hair must always be dried after washing to protect the bonds and attachments.

• Extensions require more regular brushing throughout the day to keep them smooth and healthy.

With proper care, your extensions will remain beautiful, comfortable, and long-lasting.

Great Lengths hair extensions must always be removed by one of our certified stylists.
For GL Pre-bonded, the stylist will use a specially formulated Great Lengths removal gel. When applied, this gel gently breaks down the bonds and your stylist will use a removal tool during this process, allowing the extensionist to slide the bond down your own hair with no damage caused.
GL Tapes are removed by using the specially formulated GL Tape removal spray, which breaks down the adhesive strip between the two sandwiches, meaning your stylist can remove without causing any damage.

Once you have had your extensions removed, your hair needs to be washed and conditioned to clean away any residue from the removal gel or spray.
If you have maintained your extensions well, there will be no damage, and you may find that your natural hair has grown more quickly than usual.

Yes, it can be coloured or tonalized. Your stylist will be able to advise you on what is possible and what results you can expect to achieve.

The extensions are modulated so that the hair falls naturally. If you like to wear your hair tied up, please inform your stylist, they will work your hair extensions so that they are not visible even with tied hair.

Yes, Great Lengths hair extensions suit most lifestyles, however, we recommend to avoid daily or frequently repeated swimming, particularly in seawater and chlorinated water, and excessive sauna and steam room use, as these activities may affect the lifespan of your GL Pre-bonded or GL Tapes. A great tip to try after these activities is to use diluted Great Lengths Anti Tap Water solution to restore your hair and scalp to its natural pH balance.

Yes — you can safely style your extensions with curling irons, flat irons, and other hot tools. To protect both your natural hair and your extensions:

• Always apply a professional-grade heat protectant before styling.
