Non-Damaging
Tape-In vs Sew-In
Glamour Locks #1
Not all hair extension methods are created equal. Some can seriously damage your natural hair, leading to breakage, bald spots, or long-term thinning. In this guide, we review the most popular hair extension methods and rank them from most damaging to least damaging so you can choose the best option for your hair.
#1 — Most Damaging: Tape-In Extensions
Tape-in hair extensions use small sections of extension hair with adhesive tape at the top, pressed directly onto your natural hair. While they might seem convenient, tape-ins are one of the most damaging methods available. The adhesive adds weight and strain to your roots. When you factor in brushing, styling, and everyday wear, that constant pull can lead to breakage at the root, thinning over time, and bald spots where the tapes were attached.
If you are adding a lot of length and volume, you may be adding over 5 ounces of extension hair — roughly the weight of a billiard ball — pulling down on your natural hair and scalp.
#2 — Highly Damaging: Micro-Link / I-Tip Extensions
Micro-link extensions go by many names — i-tip, micro ring, micro bead, i-link, loop, and cold fusion extensions. Regardless of the name, the method is the same: each strand of extension hair has a small metal bead clamped shut onto a small section of your natural hair.
Many salons claim micro-links don’t cause damage when applied correctly. The reality is that they create a great deal of tension on very small sections of hair. Because your natural hair sheds 80–100 strands per day, fewer and fewer hairs end up holding each bead over time. By the time you come in for removal, the bead may be hanging on by just a few fragile hairs — increasing the risk of those hairs being ripped from the scalp.
Other common issues include falling out when conditioner or oils are used near the beads, severe knotting and matting, application times up to 5 hours, costs up to $2,500, and discomfort sleeping on the beads.
#3 — Damaging: Keratin Bond Extensions
Keratin bond extensions use a keratin-based glue melted with a heated tool and fused directly to your natural hair. Because the bond is attached directly to small sections of your hair, the weight of each extension pulls at the root day after day — meaning breakage and damage are almost guaranteed over time. Like other individual methods, keratin bonds are also more prone to matting and tangling, making removal long, tedious, and often damaging.
#4 — Damaging: Braid and Sew Extensions
Braid and sew is one of the oldest and most traditional methods. Your stylist creates tight braids across the back of your head, then sews the weft into the braid. The braid itself places tension on your natural hair — and once the weft is attached, that tension increases even more. Over time this can cause severe bald spots along the braids. This method should not be confused with modern, low-tension weft methods like the Glamour Locks System.
#5 — Safer: Beaded / Sew-In Weft Extensions
Beaded weft systems (also called sew-in or invisible weft extensions) are a newer, safer category. Your stylist creates a clean row parting across the back of your scalp, then sews a hair weft — a bundle of hair sewn together horizontally at the top — onto the row using small beads and thread.
Beaded weft systems are less damaging than individual methods, but the amount of strain on your hair still depends on how the weight of the weft is supported.
#6 — Least Damaging: The Glamour Locks System
The Glamour Locks Hair Extension System is the only patented and guaranteed non-damaging hair extension method available today. It was designed to keep all the benefits of extensions — length, fullness, volume — while removing every damage-causing element like direct tension, glue, and heat.
The key is a patented tool called the Tension Strap — a barrier between your natural hair and the weight of the extension hair. The Tension Strap bears the weight of the extension hair, not your natural hair.
Minimal stress on your scalp
No pulling on fragile strands
Comfortable, long-term wear
Truly guaranteed non-damaging
What Makes Hair Extensions Non-Damaging?
Non-damaging hair extensions are those that do not place direct stress on your natural hair. Any method that anchors extension hair directly to small sections of your own hair — using glue, beads, or tight braids — can lead to breakage at the root, bald spots and thinning, and long-term damage that can take years to repair.
Methods that distribute the weight across a support structure — like the Glamour Locks Tension Strap — offer the least damaging option available. For those who need volume or length on the top of the head, learn more about our Crown Fusion Hair Extensions.
