Everything You Need to Know About the Invisible CombLine® Extensions

First—the very basics. The CombLine application system is a groundbreaking hair enhancement technique that allows stylists to create invisible and lightweight bonds. Using their favorite extension brand, stylists can achieve this hair-on-hair attachment with a comb-shaped tool and a medical-grade glue. Designed for both lengthening and thickening, suitable for all genders and ages, the CombLine application is truly a full-solution technique.  

CombLine is one of the latest hair extension methods on the market and is capturing the attention of salon professionals with its unmatched results. 2,500 stylists receive certification annually in the United States, indicating a potential for this cutting-edge alternative to exceed traditional methods such as weft and fusion.  

Without a doubt, one of the biggest appeals of this new hair extension technique is its invisible bond. Yes, that means exposed beads and bands can be a thing of the past with CombLine.  

To be clear, CombLine is not an extension itself—rather, it is a system for installing any extension brand or type. Of course, the extension quality you choose will determine the seamlessness of the final transformation. Opting for 100% Remy hair, the recommended hair grade for professionals, minimizes the risk of tangling and creates the most natural look possible. At hairtalk, we prioritize 100% Remy quality where cuticles are aligned in the same direction to reduce breakage. 

Think of the application in terms of eyelash extensions versus false lashes. While false lashes may be a quick, at-home solution, using glue to apply a chain of lashes to the skin does not always yield the most discreet result. Eyelash extensions, on the other hand, are attached directly to the lash, each strand applied one by one. CombLine Extensions follow a similar thread. Instead of just placing glue on the back of a hair weft and sticking it beneath your section, CombLine’s advanced system connects the extension to the hair itself.  

A CombLine application lasts 8 weeks with proper care. The bonds will naturally come out over time, just as the natural hair sheds minimally with brushing. Any hair that remains when it is time for a new application can be removed with a gentle solvent.  

Similarly to keratin extensions, the CombLine system does not allow the hair to be reused once applied.  

For at least 24 hours the application, do not wash the hair, avoid using hot tools or chemical treatments, and gently brush the hair from mid lengths to ends.  

In the weeks after the application, be sure to avoid over-washing the hair which can strip the scalp of its natural oils. Cuticles are in their most delicate form when wet, and strands can easily snag when brushed against pillows in this state. Consequently, never sleep with wet hair and consider using a silk pillowcase instead. Tying the hair back in a loose, low ponytail or braid can also help reduce the risk of breakage.  

When using hot tools, avoiding the bond is especially important for CombLine hair extensions—do not risk prematurely breaking it down. Use heat protectant to limit the amount of heat the hair absorbs.  

Because of the hair-on-hair attachment, CombLine extensions are a great alternative to other extension methods for those with active lifestyles. Unlike weft extensions, for example, whose beads may slip from sweating, the CombLine bond has more security. Give the extension the best care possible by always tying the hair back in a soft ponytail or braid while exercising. Consider mixing water with a deep conditioning mask and applying it from mid-lengths through the ends if the hair may encounter chlorine, salt, sunscreen, or tanning products to avoid discoloration. Wash the hair after sweating or swimming to prevent mineral buildup.  

Consider one of the most frustrating battles for those with thin hair: wearing extensions may be more pivotal than any other hair texture, yet this hair type demands the most delicate, precise installations. The CombLine technique, fortunately, is one of the best ways to apply extensions for thin hair.  

Because the extension attaches to the hair itself, fragile hair strands will not be at risk of being pulled by heavier attachment points. Since this new extension technology has one of the most invisible results on the market, it also does not require a lot of hair to conceal the attachments. Plus, taking a targeted approach also ensures users only have to wear the extensions in the areas most needing fullness.  

We associate the CombLine hair enhancement system most often with those who have extreme hair loss. And yes, for someone experiencing thinning near the crown, the CombLine method brings remarkable fullness and is more discreet than a wig could ever achieve. However, that doesn’t mean other hair concerns cannot benefit from the CombLine system as well.  

Perhaps a salon guest is looking to add length with the most natural transition between their own hair and the extension. Maybe a routine clip-in wearer wants to pull their hair in a ponytail without worrying the extensions will show. Perhaps someone with fragile hair has experienced snagging from bulky extensions. Whatever the problem, the CombLine system can meet a variety textures and tresses. 

V-Light extensions, another recent extension technology, are often compared to the CombLine system as both make use of a comb-like tool to create invisible bonds. Unlike the CombLine hair enhancement, which attaches through the comb alone, V-Light extensions require a UV light to cure the extension bond. Stylists find that this additional step in the attachment process can make a V-Light installation slower.  

Moreover, just as gel nail polish (which requires a UV light to cure) is thicker than regular nail polish, an extension adhesive set with UV light is thicker as well. Because CombLine extensions don’t require this curing, the adhesive is thinner and more flexible, melding more seamlessly with the natural hair. 

All in all, the CombLine extension method is transforming the hair extension industry for its advantages over other popular methods: 

1. Seamless: While many extension brands claim to offer undetectable results, this method of joining the natural hair with the extension truly is unique in the industry.
2. Versatile: Effective for all ages and genders; designed for thickening and lengthening; applicable for the fringe, top, sides, and crown—most extensions in the market fail to meet all these features, but the CombLine system checks every box. 
3. Comfortable: Because the CombLine system makes use of a medical-grade glue instead of bulkier application points like beads, the extensions are gentler to sleep on compared to other methods. 
4. Lightweight: Opting for a thin glue over the denser V-Light glue or heavier silicone extension beads makes for a lighter alternative.
5. Thin-hair friendly: Homing in on small sections of the hair results in less weight on the scalp compared to installing a full weft of hair, for example. Making use of a hair-on-hair attachment also restricts the extensions from pulling at the natural strands.  

Undoubtedly, beauty moves fast, and keeping up with innovations is a necessary part of any stylist’s career. With the increasing demand for hair growth treatments and supplements, the global hair thinning market is projected to steadily grow in the next decade and was estimated at $1.4 billion in 2023. 

As a first-of-its-kind application technique, the CombLine method cannot be mastered without the support of specialized educators. Even seasoned extension stylists should not disregard the importance of training, as investing in quality education ensures they achieve the most precise results possible. While online tutorials can be a nice introduction, only with credible training programs can you engage with educators in real time, practice the method hands-on with other stylists, and ask questions only advanced educators could answer.
