Keratin Glue Sticks for Hair Extensions: Tipping, Re-Tipping & Bonding Guide
Keratin glue sticks are professional bonding products used when creating, replacing or reshaping compatible hair extension attachments. They are designed to be heated using a suitable glue gun so the softened keratin can be applied to prepared extension hair and formed into the required attachment.
HairX Keratin Glue Sticks are available in Amber, Black and Brown, with both smaller 6mm sticks and larger 12mm options available. The correct size should always be matched to a compatible glue gun.
They can be useful for professional hair extension tipping, re-tipping, rebonding and preparation of suitable pre-bonded extension hair.

What Are Keratin Glue Sticks?
Keratin glue sticks are solid lengths of bonding material designed to be softened inside a compatible hot glue gun.
Once heated, an appropriate amount of softened keratin can be applied to suitable extension hair and shaped into a compatible attachment.
Unlike ready-made pre-bonded extensions, glue sticks are a preparation material rather than a complete extension strand.
What Are Keratin Glue Sticks Used For?
Professional uses can include:
- Creating compatible pre-bonded hair extension tips
- Re-tipping suitable previously worn extension hair
- Replacing old or damaged keratin attachments
- Preparing compatible Nail-Tip / U-Tip extension strands
- Reshaping suitable keratin attachments
- Creating new bonds on compatible loose extension hair
Are Keratin Glue Sticks the Same as Hair Extensions?
No.
The glue stick provides the bonding material used to create an attachment. The extension hair itself is separate.
How Are Keratin Glue Sticks Different from Keratin Grain?
The main difference is the format of the bonding material.
Keratin Grain is supplied as loose granules that are heated using suitable professional equipment, while glue sticks are solid sticks designed for use with a compatible glue gun.
Both formats allow a trained professional to control the amount of bonding material used when preparing an extension strand.
How Are Keratin Glue Sticks Different from Keratin Rebonds?
Keratin Rebonds are supplied as individual pre-shaped pieces of bonding material.
Glue sticks, by comparison, are fed through a compatible glue gun and softened as required.
Neither format is automatically better. The most suitable option depends on the professional preparation technique and the type of attachment being created.
What Sizes of Keratin Glue Sticks Are Available?
The HairX range includes both smaller and larger glue sticks.
| Glue Stick Size | Typical Equipment |
|---|---|
| 6mm | Compatible small glue gun |
| 12mm | Compatible large hot glue gun |
Always check the specifications of the glue gun before inserting or heating a keratin stick. The glue-stick diameter must be compatible with the equipment being used.
Does the Glue Gun Size Matter?
Yes.
A glue stick needs to fit the equipment correctly. A 12mm stick should not be forced into equipment designed for a smaller diameter, and a smaller stick may not feed correctly through equipment designed for larger sticks.
Use professional equipment that is compatible with the specific diameter and bonding material being used.
What Colours Are Keratin Glue Sticks Available In?
The HairX range includes:
- Amber
- Black
- Brown
Different colours allow the professional to choose a bonding material that coordinates more naturally with the extension shade and surrounding natural hair.
Does Glue Stick Colour Affect Bond Strength?
Colour should not be treated as an indication of strength.
The finished attachment depends much more on compatibility, extension preparation, amount of keratin used, bond formation, fitting technique and subsequent wear.
When Might Amber Keratin Glue Sticks Be Used?
Amber provides a warmer-toned bonding option that can work well where a lighter or warmer attachment colour is appropriate.
The final choice should still be based on the actual extension and natural-hair shade rather than assuming Amber is suitable for every blonde or lighter colour.
When Might Black Keratin Glue Sticks Be Used?
Black provides a darker keratin option where a darker attachment is more suitable for the extension and natural hair being prepared.
When Might Brown Keratin Glue Sticks Be Used?
Brown offers another darker neutral option for compatible brunette and deeper extension shades.
Can Keratin Glue Sticks Be Used for Re-Tipping Hair Extensions?
Yes, where suitable extension hair remains in good enough condition for professional reuse.
Re-tipping involves removing or preparing the old attachment and creating a fresh compatible tip before the extension is professionally fitted again.
Before re-tipping, the extension hair should be inspected for dryness, excessive thinning, tangling, heat damage, chemical damage and deterioration around the previous attachment.
Does Re-Tipping Make Old Extensions New Again?
No.
Creating a fresh bond only replaces the attachment. It does not reverse previous wear through the extension lengths.
If the extension hair has become severely dry, tangled, brittle or thin, replacement may be more appropriate than creating another new bond.
How Should Old Extension Hair Be Prepared?
Before applying fresh keratin:
- Assess whether the extension strand is still suitable for reuse
- Remove old compatible bonding residue correctly
- Keep the attachment area clean and dry
- Avoid oils and heavy conditioner around the prepared tip
- Organise extension strands by colour and length
- Discard strands that are no longer suitable for professional reapplication
How Are Keratin Glue Sticks Used?
The exact professional technique can vary, but the basic preparation process may include:
- Select a compatible keratin glue stick and glue gun.
- Allow the equipment to heat according to its operating instructions.
- Prepare the top of the extension strand.
- Dispense an appropriate amount of softened keratin.
- Work the bonding material around the extension hairs.
- Shape the keratin into the attachment required for the intended method.
- Allow the newly created attachment to cool fully.
- Inspect the finished tip before fitting or storage.
How Much Keratin Should Be Used?
There is no universal quantity suitable for every extension strand.
The amount depends on factors including:
- Extension strand weight
- Attachment width
- Attachment thickness
- Finished tip shape
- Extension fitting method
- Professional preparation technique
Using more keratin does not automatically create a better or stronger attachment.
Can a Keratin Bond Be Too Large?
Yes.
An unnecessarily bulky bond can be more difficult to conceal, may feel uncomfortable and may not suit the intended fitting method.
Can a Keratin Bond Be Too Small?
Yes.
If insufficient bonding material is used, the attachment may not contain the extension hairs securely enough.
Can Keratin Glue Sticks Be Used for Nail-Tip / U-Tip Extensions?
Suitable keratin glue sticks can be used during professional preparation of compatible Nail-Tip / U-Tip and other selected pre-bonded extensions where the bonding material and preparation method are appropriate.
Once the extension strand has been prepared, a compatible Nail-Tip attachment is professionally fitted using suitable heat-fusion equipment.
You can read our Nail-Tip / U-Tip Fitting Guide for more information about professional application.
Can Keratin Glue Sticks Be Used to Create Stick-Tip Style Attachments?
A trained professional may create a narrow compatible keratin attachment intended for a suitable ring-based fitting system.
The finished tip needs to fit correctly inside the chosen ring and should be prepared specifically for the intended method.
Do Prepared Stick-Tips Use Heat During Fitting?
Not during standard Micro Ring fitting.
The keratin may be heated while the extension tip itself is being prepared, but once a compatible Stick-Tip strand is ready, the extension is normally secured to the client's natural hair using a suitable Micro Ring.
Can You Use Any Hot Glue Gun?
No.
The equipment needs to be compatible with the diameter of the glue stick and suitable for professional extension preparation.
Follow the operating instructions for the equipment and bonding product rather than improvising with unsuitable tools.
What Temperature Should Keratin Glue Sticks Be Heated To?
There is no single temperature that should be assumed correct for every glue gun or keratin product.
Heating equipment varies in design, temperature control and heat transfer, so use the operating guidance for the specific professional equipment being used.
Does More Heat Make a Better Bond?
No.
Excessive heat should not be used as a shortcut to create a stronger attachment.
The keratin only needs to be softened enough to be worked using the correct professional technique.
Why Is Heat Safety Important?
Glue guns, heated surfaces and softened keratin can become hot enough to cause burns.
Professional heat-resistant equipment and an appropriate work surface should be used, and heated tools should be kept away from skin.
Should Keratin Glue Sticks Be Used at Home?
HairX recommends professional use.
Creating extension attachments requires control of heat, keratin quantity, strand weight, bond size and attachment shape, so professional training and experience are important.
Can Keratin Glue Stick Bonds Be Removed?
Yes, where the bonding system is compatible with the professional removal process being used.
Compatible keratin attachments may require suitable bond-removal pliers together with an appropriate bond remover depending on the specific bonding system.
Do not pull an intact bonded extension from the natural hair.
For more detail, read our Nail-Tip / U-Tip Removal Guide.
Can Old Keratin Be Reheated and Reused?
Do not assume an old worn attachment should simply be reheated and incorporated into a new bond.
Old or deteriorated bonding material should be assessed and removed appropriately so the extension strand can be prepared cleanly before a new attachment is created.
Can Keratin Glue Sticks Be Used with Bulk Extension Hair?
Potentially, where the hair is suitable for professional pre-bonded preparation.
The extension hair needs to be divided into suitable strand weights and the finished attachment should match the intended professional fitting system.
What Is the Difference Between Glue Sticks, Grain and Rebonds?
| Keratin Product | Format | Typical Professional Preparation |
|---|---|---|
| Glue Sticks | Solid sticks | Softened using a compatible glue gun |
| Keratin Grain | Loose granules | Softened using compatible professional heating equipment |
| Keratin Rebonds | Individual pre-shaped pieces | Softened during professional bond preparation |
Which Keratin Bonding Format Should You Choose?
There is no single best option for every professional.
Glue sticks may suit extensionists who prefer dispensing softened keratin directly from a compatible glue gun. Grain gives greater control over loose granule quantity, while Rebonds provide convenient individual pre-shaped pieces.
The best choice is the product compatible with the extension system, equipment and preparation technique being used.
How Should Keratin Glue Sticks Be Stored?
Keep unused glue sticks clean, dry and away from unnecessary heat, moisture and contamination.
Avoid leaving them beside heated equipment or in environments where the sticks may soften, distort or become contaminated before use.

Final Thoughts
Keratin glue sticks provide a practical professional bonding format for creating, replacing and reshaping compatible hair extension attachments.
The HairX range includes Amber, Black and Brown options in smaller 6mm and larger 12mm formats, allowing professionals to select a stick suitable for their compatible glue gun and intended preparation technique.
The key is not simply melting keratin onto extension hair. Good preparation depends on assessing the condition of the strand, removing unsuitable old bonding material, selecting the correct equipment, controlling the amount of keratin used and creating an attachment that suits the intended fitting system.
Where previously worn extension hair remains in suitable condition, professional re-tipping can provide a fresh attachment for another fitting. However, a new keratin bond cannot restore extension lengths that are already excessively dry, thin, tangled or damaged.
Used with compatible equipment and professional technique, keratin glue sticks offer another flexible bonding option alongside Keratin Grain and pre-shaped Keratin Rebonds.
