When considering prebonded hair extensions, have you ever been deterred by the terrifying rumors circulating online? “You’ll tear out your hair!” “You’ll be completely covered in glue after you remove it, ruining your hair!” “You’ll definitely get an itchy scalp!” These outrageous claims have spread like wildfire, deterring many from this technology, often touted as the “most invisible.” But what’s the truth? This article will serve as your myth buster, addressing three of the most common fears with expert knowledge and objective facts. It will help you understand the true nature of prebonded hair extensions, empowering you to make a confident, beautiful decision based on facts, not fear.
At Full Shine, we only use Italian Keratin Technology. Unlike industrial glues, our bonds are made of the same protein found in your natural hair, ensuring a healthy blend that breathes with your scalp.
Myth 1: Will They Damage My Natural Hair?
This is the most common and biggest misconception.
The Common Fear:
“Glue will stick to and tear your hair, and removal will inevitably pull your natural hair out.”

The Reality: Why It’s Actually Safe for Your Strands
The root cause of damage is the person, not the technique: Any hair extension method carries the risk of damage if installed and removed improperly. Pre-bonded extensions can be damaged primarily by: ① The stylist using low-quality glue; ② The bond point is too close to the hair root during installation; ③ Forceful removal (directly pulling). These problems can be completely avoided by a professional stylist using a specialized solvent.
Professional removal involves “dissolving,” not “tearing”: A proper removal process is never about pulling or yanking. The stylist will carefully apply a specialized adhesive remover to each bond point. This solvent precisely dissolves the adhesive, allowing the extension strands to slide off easily and painlessly without tangling or pulling on your natural hair.
Expert Tip: The Secret to a Damage-Free Experience
Damage is not inevitable. It is far more important to invest your budget in finding a professional hair extension artist with rich experience and good reputation than to deal with it afterward. A professional installation and removal will cause minimal damage to your hair.
Myth 2: Is the “Glue” Impossible to Remove?
This myth causes many people to worry that hair will become stiff, tangled, and unmanageable after removal.
The Common Fear:
“After removal, hair is left with clumps of glue that are as hard as rock and impossible to comb through. You’ll end up having to cut the stuck hair.”

The Reality: How Keratin Bonds Dissolve Cleanly
It’s still a technical issue: Excessive glue residue is almost always caused by using low-quality, unprofessional hot melt glue, or not using enough or the correct solvent during removal.
Professional Process Ensures Cleanliness: In professional salons, removal is a two-step process: ① Dissolving: Using a glue remover to fully soften the glue; ② Cleaning: After the glue is dissolved, the stylist will thoroughly wash the hair with a professional hair care product (such as a glue-removing shampoo or conditioner) to ensure all residue is removed and restore hair’s smoothness.
Expert Tip: Why Professional Removal is a Must
Residue is completely avoidable. After removal, your hair should be as fresh and clean as before the installation. If you notice your stylist attempting to remove the glue violently or without using a solvent, stop immediately.
Full Shine bonds are designed to be Thermoplastic. This means they soften perfectly under controlled heat for installation and dissolve completely with our professional-grade remover—leaving zero sticky residue on your natural hair.
Myth 3: Can the Bonds Cause Scalp Itching or Allergies?
Concerns about allergies to chemical products are legitimate, but we need to approach them scientifically.
The Common Fear:
“Chemicals in glue can come into direct contact with the scalp, causing itching, redness, and folliculitis.”

The Reality: Medical-Grade Keratin vs. Cheap Adhesives
Safe Distance: A golden rule for professional pre-bonded installation is that the bond point must be at least 1 cm from the scalp. The glue only adheres to your hair strands and never comes into direct contact with your scalp. This physically isolates allergens.
Hypoallergenic Testing: Most high-quality hair extension glues are hypoallergenic. If you have extremely sensitive skin, you can ask your stylist to perform a skin allergy test before installation (usually by applying a small amount of glue behind your ear or on the inside of your arm).
The Real Culprit: Scalp issues are more likely due to improper cleanliness (sweat and shampoo residue can accumulate in the hair roots near the bond point, breeding bacteria) than the glue itself.
Expert Tip: How to Do a Simple Patch Test First
The risk of allergies is extremely low. Choosing regular products and having a professional hairstylist perform the procedure (ensuring distance) can effectively prevent it. Keeping the scalp clean is the key to maintaining a healthy scalp.

As we’ve seen, the three core fears surrounding prebonded hair extensions ultimately point to the same solution: professional technology and products. Rumors often stem from inappropriate experiences and misinformation, but the truth is, a mature technology itself is innocent; its effectiveness depends entirely on how it is used.
