Great Lengths Hair Extensions Reviews and FAQ

Looking for premium length and volume without risking your natural hair? Great Lengths is one of the most talked-about extension brands, but is it really worth the hype and the cost?

Great Lengths hair extensions use double-drawn, 100% Remy human hair and are professionally applied with keratin bonds, loved for their natural look, strong hold, and long-lasting quality.

People ask if Great Lengths offers true quality and safety for their natural hair. Here’s what I found after using them and talking to stylists and other clients.

Is Great Lengths real hair?

You want extensions to blend perfectly, move naturally, and feel like your own hair—but are they actually made from real human hair?

Yes, Great Lengths uses 100% Remy human hair, sourced ethically from Indian temples, ensuring soft texture, natural direction, and a believable finish.

Each strand of Great Lengths hair is sourced as temple donations¹, then kept with cuticles aligned for that true “Remy²” texture—so hair doesn’t tangle easily and shines realistically. Their processing is gentle, using osmosis and low chemical treatments to keep the hair feeling as strong as it started. In my experience, the extensions looked and moved like my own hair, and color blending was easy, thanks to the many tones they offer. The attention to where hair comes from also means you can wear them knowing everything is above-board and ethical.

How long does Great Lengths hair last?

When you invest in top-tier extensions, you expect them to stick with you for a while. Just how long do Great Lengths hold up?

Great Lengths extensions last 3–6 months for most people with proper care, staying secure, tangle-free, and natural-looking during daily wear.

The actual lifespan depends on how quickly your hair grows and how well you follow aftercare instructions³ from your certified stylist. I wore mine for almost five months and they still looked good—no matting at the bonds, no weird shedding, and the hair kept its shine. Regular brushing at the roots, gentle washing, and avoiding oil-based products at the bonds keep them going strong. Most stylists recommend removal as your roots grow out, or when you start to notice too much distance from the scalp, which can stress your natural hair.

Are Great Lengths hair extensions damaging?

Everyone worries about losing their real hair to extensions. Are Great Lengths gentle enough for daily wear?

When applied and cared for correctly, Great Lengths extensions do not damage natural hair; their keratin bonds are gentle and designed to move with your own hair.

Unlike glue-in or metal-clip methods, Great Lengths’ keratin bonds⁴ are flexible, mimicking the shape and weight of a natural strand. This keeps them from pulling or breaking your hair. My stylist explained that installation by an expert ensures each bond is customized for your own thickness. I was careful not to tug on the bonds and followed maintenance steps—such as not sleeping with wet hair and using a silk pillowcase. The key is professional installation⁵ and removal; DIY jobs can cause breakage or tangling, which is why the company only sells to trained salons.

How much are Great Lengths?

Everyone’s budget is different, so how much does it really cost to get these luxury extensions?

Great Lengths hair extensions cost between $800 and $2,500, depending on hair length, thickness, and your salon’s rates.

The smallest, partial installs for volume start at around $800 to $1,200. Full-head extensions using longer strands can reach prices up to $2,000 or more. The price includes professional consultation, custom blending, and installation by a certified stylist. The price is much higher than other simila brands,such as Findingdream, Luxy Hair or bellami. After paying upfront, budget for maintenance appointments every couple of months, which may cost extra but keep hair looking natural. While the costs are high, I felt the results justified it—the transformation is dramatic, with minimal risk to your natural hair.

How to remove Great Lengths?

Removal is important for hair health—so how is it done safely?

Great Lengths extensions must be removed by a certified stylist using a keratin bond dissolver and a gentle, controlled process to prevent hair damage.

Do not pull or cut the bonds yourself—this risks breakage or even removing clumps of your natural hair. Stylists use a special solution to soften the keratin bond, and then gently slide out each extension using a precise tool. It took under two hours for my full set to come out, and I lost very little hair—a small, expected amount due to normal shedding. Removal is included with most professional services, and your hair should look and feel healthy afterward if everything is done correctly.

How to sleep with Great Lengths hair extensions?

Sleep can be “make or break” for extensions. What’s the right routine?

Tie Great Lengths hair in a loose braid or ponytail, use a silk or satin pillowcase, and never sleep with wet hair to keep extensions smooth and tangle-free.

I switched to a silk pillowcase and got into the habit of gently braiding my hair before bed. This keeps bonds from rubbing and stops mid-lengths from tangling. If you have layers, a low ponytail wrapped in a soft scrunchie also works. Avoiding wet hair is key because it weakens the bonds and causes matting. I also used a soft bristle brush⁶ and detangled carefully at the roots each morning, which extended the lifespan of my Great Lengths enormously.

Can you swim with Great Lengths extensions?

Vacations and workouts often mean pools or oceans—is swimming safe?

Yes, you can swim with Great Lengths extensions; always wet hair with tap water, use swim caps when possible, and rinse out salt or chlorine immediately after swimming.

Chlorine and salt water can dry out extension hair, so I learned to prep my hair with a quick rinse before jumping in—hair already wet soaks up less pool or ocean water. Swim caps help but aren’t essential unless you’re in chemically treated water often. After a swim, rinse again and apply a leave-in conditioner⁷. I always brushed out tangles as soon as my hair dried and scheduled extra hydration treatments in summer. Use a wide-tooth comb⁸ to gently detangle, especially after outdoor activities.

Are Great Lengths Extensions Worth It?

Luxury extensions cost time and money—so is the investment justified?

Great Lengths extensions are worth it for those seeking lasting, natural-looking extensions that are gentle on hair with expert installation and top quality Remy human hair.

After using lower-priced brands, the difference with Great Lengths⁹ was clear—no odd shine, no tangling, and the bonds felt almost invisible. My confidence grew and daily styling became faster. Stylists who use Great Lengths say the hair remains soft, manageable, and the bonds cause less irritation or breakage, especially with regular trims and the right aftercare. For anyone serious about a major transformation and ready to invest in aftercare, these extensions deliver on their promise of seamless, long-term length and volume.

Is Great Lengths hair extensions a good brand for not damaging hair?

Gentle attachment is the number one concern—does Great Lengths protect your real hair?

Yes, Great Lengths is known for its gentle keratin bond system, which is less damaging when fitted and removed by professionals, keeping natural hair safe and healthy.

Great Lengths was developed in Italy by scientists studying hair structure, so their keratin tips¹⁰ are designed to mimic human hair bonds for safety and flexibility. I noticed no breakage at removal, and my stylist explained this is because the bond never gets too hard or sticky. Regular maintenance and careful brushing help, but the professional bond is the biggest reason these extensions are chosen by people who want to avoid hair loss¹¹ or snapping. The few problems that do happen are almost always from improper DIY removal or poor at-home care, not the extensions themselves.

Problems with Great Lengths extensions

Even the best brands aren’t perfect—what are real users’ biggest complaints?

The most common problems with Great Lengths extensions are the high cost, limited DIY options, possible slipping bonds if incorrectly applied, and the need for regular professional maintenance.

Cost is the number one barrier—these extensions are one of the most expensive on the market, which puts them out of reach for many people. Some users have reported allergies to the keratin bond, though this is rare. Others find it restrictive to always need a salon visit for removal or maintenance—no DIY tricks allowed. If your stylist isn’t trained, slipping and uneven bond placement can happen, leading to early fall-out or tangling. Aftercare routines are non-negotiable: skipping them can cause buildup, matting, or even damage over time. But overall, for those who follow the rules and can afford the price, complaints stay minimal.

Conclusion

Great Lengths offers real Remy hair, keratin bonds, and pro application for natural results that last months. With good aftercare and expert stylists, they’re worth the investment—and much safer than most alternatives.
