Keratin Rebonds for Hair Extensions: Re-Tipping & Reapplication Guide
Keratin rebonds are pre-shaped pieces of keratin material used by trained hair extension professionals when creating, replacing or rebuilding compatible pre-bonded hair extension attachments.
They are particularly useful when suitable extension hair is being professionally prepared for reapplication and the original keratin attachment can no longer be reused.
The HairX Keratin Rebond range is available in Clear, Amber, Brown and Black, allowing the attachment colour to be selected according to the extension shade, natural hair and professional fitting requirements.
✔ Approximately 100 rebonds per pack
✔ Pre-shaped keratin pieces
✔ Available in Clear, Amber, Brown and Black
✔ Designed for compatible pre-bonded hair extension attachments
✔ Can be used when professionally re-tipping suitable extension hair
✔ Applied using a suitable professional heat-fusion technique
✔ Professional training recommended
What Are Keratin Rebonds?
Keratin rebonds are small pre-shaped pieces of bonding material designed for compatible hair extension preparation and heat-fusion application.
Rather than using a complete new pre-bonded extension strand, a rebond can be used when suitable extension hair needs a fresh keratin attachment.
What Are Keratin Rebonds Used For?
Professional uses can include:
- Re-tipping suitable pre-bonded extension hair
- Replacing old keratin attachments
- Preparing suitable extension strands for reapplication
- Creating compatible pre-bonded strands from suitable loose extension hair
- Rebuilding damaged or removed keratin tips where appropriate
Are Keratin Rebonds Hair Extensions?
No.
The rebond is the bonding material used to create the attachment at the top of a compatible extension strand.
The extension hair itself is separate.
Are Keratin Rebonds the Same as Nail-Tip Hair Extensions?
No.
Nail-Tip / U-Tip extensions are complete individual extension strands already supplied with a pre-bonded keratin attachment.
Keratin rebonds are separate pre-shaped pieces used when a professional needs to create or replace a compatible attachment.
What Does Re-Tipping Hair Extensions Mean?
Re-tipping means creating a new attachment at the top of suitable extension hair after an old attachment has been professionally removed or is no longer suitable for reuse.
The extension hair should always be assessed first to make sure it remains in suitable condition.
What Does Rebonding Hair Extensions Mean?
Rebonding generally refers to rebuilding the keratin attachment on compatible extension hair so the strand can be professionally prepared for future application.
Can Old Nail-Tip Hair Extensions Be Rebonded?
Potentially.
If the extension hair remains in suitable condition after professional removal, the old attachment can be removed and the hair may be prepared with a new compatible keratin bond.
Can Every Removed Extension Strand Be Rebonded?
No.
The extension hair should be inspected first.
Rebonding may not be worthwhile where the strand has become:
- Severely dry
- Very thin through the ends
- Heavily tangled
- Heat damaged
- Significantly chemically damaged
- Damaged around the original attachment
Why Inspect the Extension Hair Before Re-Tipping?
A new keratin attachment does not restore damaged extension hair.
The condition of the hair itself should therefore be considered separately from the condition of the bond.
Rebonding replaces or creates the attachment. It does not repair extension hair that is already excessively dry, thin, tangled or damaged.
How Many Keratin Rebonds Are in a Pack?
HairX Keratin Rebonds are supplied in packs containing approximately 100 individual rebonds.
What Colours Are Keratin Rebonds Available In?
The HairX range currently includes:
- Clear
- Amber
- Brown
- Black
Why Does Keratin Rebond Colour Matter?
The colour of the finished attachment can affect how noticeable the bond appears underneath the client's natural hair.
The most appropriate colour depends on factors including:
- Natural hair colour
- Extension colour
- Attachment placement
- Hair density
- Professional preference
When Should Clear Keratin Rebonds Be Used?
Clear rebonds provide a neutral option where a strongly coloured attachment is not required.
The appearance of the finished bond will still depend on the hair surrounding it and the amount of keratin used.
When Should Amber Keratin Rebonds Be Used?
Amber provides a warmer-toned keratin option that may coordinate well with certain blonde, warm brunette or golden extension shades.
When Should Brown Keratin Rebonds Be Used?
Brown rebonds provide a darker neutral option for compatible brunette extension colours.
When Should Black Keratin Rebonds Be Used?
Black rebonds provide the darkest attachment colour within the HairX rebond range and may be useful where the extension and natural hair are very dark.
Does the Rebond Colour Have to Match the Extension Exactly?
Not necessarily.
The aim is normally to choose an attachment colour that sits discreetly within the surrounding hair while remaining suitable for the professional fitting technique being used.
Should You Choose Rebond Colour from a Screen?
Where possible, consider the actual extension and natural hair colours rather than relying entirely on screen appearance.
Lighting and display settings can affect how colours appear online.
How Are Keratin Rebonds Applied?
A professional re-tipping process may involve:
- Assessing the condition of the extension hair.
- Removing remaining old keratin or adhesive residue.
- Preparing a clean extension strand.
- Selecting a suitable rebond colour.
- Positioning the keratin rebond with the prepared extension hair.
- Softening the rebond using suitable professional heat-fusion equipment.
- Forming the softened keratin securely around the extension hair.
- Allowing the newly created tip to cool.
- Inspecting the finished attachment before application.
Do Keratin Rebonds Need Heat?
Yes.
HairX Keratin Rebonds are designed for professional heat-fusion application.
The keratin needs to be softened using suitable heated equipment before it can be formed into the required attachment.
What Tool Is Used to Heat Keratin Rebonds?
A compatible professional heat connector can be used to soften the keratin during preparation and fitting.
Shop Professional Hair Extension Heat Connectors
Does More Heat Make a Better Rebond?
No.
Excessive heat should not be used simply in an attempt to create a stronger attachment.
Use suitable professional equipment and follow the operating guidance for the bonding material and tool.
What Temperature Should Keratin Rebonds Be Heated To?
There is no single temperature that should be assumed suitable for every keratin product and every professional heat connector.
Follow the instructions for the specific products and equipment being used.
How Long Should a Rebond Be Heated?
There is no universal number of seconds.
The keratin should only be softened sufficiently to become workable for the professional bond-forming process.
Can Keratin Be Overheated?
Yes.
Unnecessary excessive heat can make controlled bond formation more difficult and can create unnecessary risk when working close to extension hair and natural hair.
Should a Heat Connector Touch the Scalp?
No.
Heated professional fitting equipment should be kept away from the client's scalp, skin and fingers.
Should Finger Protection Be Used?
Professional finger protection can be useful when shaping suitable softened keratin according to the fitting technique being followed.
Can Keratin Rebonds Be Applied at Home?
Professional fitting is recommended.
Rebonding involves heated professional equipment, keratin preparation and attachment formation, so appropriate training and technique are important.
What Should a Finished Rebond Look Like?
A professionally created attachment should be neat, compact and appropriate for the extension strand it supports.
Oversized, irregular or poorly formed bonds may be uncomfortable, difficult to conceal or difficult to remove later.
Should a Bigger Keratin Bond Be Stronger?
Not necessarily.
More bonding material does not automatically mean a better attachment.
The bond should be appropriately sized for the extension strand and professional fitting method.
Can a Keratin Bond Be Too Small?
Yes.
If insufficient bonding material is used, the extension hair may not be held securely within the newly created attachment.
Can a Keratin Bond Be Too Large?
Yes.
An excessively bulky attachment can affect comfort, concealment and professional application.
Can Rebonded Extensions Be Fitted Like New Nail-Tips?
Once suitable extension hair has been correctly re-tipped and the new attachment has cooled and been professionally checked, it may be prepared for compatible Nail-Tip / U-Tip heat-fusion application.
How Are Rebonded Nail-Tips Fitted?
During professional application:
- A suitable natural-hair section is isolated.
- The prepared pre-bonded extension is positioned correctly.
- The keratin attachment is softened with a professional heat connector.
- The bond is carefully formed around the natural hair section.
- The attachment is allowed to cool.
- Comfort, movement and bond formation are checked.
Read Our Nail-Tip / U-Tip Fitting Guide
Are Keratin Rebonds Damage-Free?
No extension fitting should be described as completely damage-free.
Natural hair can experience unnecessary stress where extensions are unsuitable, too heavy, poorly sectioned, fitted incorrectly, maintained poorly or removed incorrectly.
Does Rebonding Make Extensions New Again?
No.
Rebonding replaces the attachment, not the extension hair itself.
The hair will still reflect its previous wear, washing, styling and environmental exposure.
Can Rebonded Extensions Last as Long as Brand-New Hair?
There is no guaranteed lifespan.
The remaining usable life of the extension hair depends on its existing condition and future aftercare.
What Is the Difference Between Keratin Rebonds and Keratin Granules?
Both products can be used for compatible professional hair extension preparation, but they are supplied in different formats.
Keratin Rebonds are already supplied as individual pre-shaped pieces.
Keratin Granules are supplied as loose individual grains that can be melted and used to create a customised quantity or shape of keratin attachment.
When Might a Professional Choose Rebonds?
Pre-shaped rebonds can be convenient where a consistent individual piece of keratin is preferred during extension preparation.
When Might a Professional Choose Keratin Granules?
Granules can provide more flexibility where the fitter wants to control the amount of loose keratin used for a particular strand or preparation method.
Are Keratin Granules the Same as Rebonds?
No.
They are different product formats even though both may be used during professional keratin extension preparation.
Do Keratin Granules Need a Melting Pot?
Depending on the product and professional technique, compatible keratin granules may be softened using a suitable keratin melting pot or compatible heated equipment.
What Colours Are HairX Keratin Granules Available In?
The current HairX Keratin Grain range includes Amber, Brown and Black options.
What Is the Difference Between Keratin Rebonds and Glue Sticks?
Rebonds are supplied as individual pre-shaped pieces designed for compatible extension attachment preparation.
Keratin-style extension glue sticks are supplied in stick form and are used with compatible professional equipment and preparation techniques.
The correct bonding product should always be chosen according to the extension system and professional method being used.
Can Rebonds Be Used on Nano Tip Extensions?
Not as a substitute for a Nano Tip attachment.
Nano Tips use a different ring-based fitting system rather than the standard Nail-Tip heat-fusion process.
Can Rebonds Be Used on Stick-Tip Extensions?
Stick-Tip / I-Tip extensions are normally fitted using compatible rings rather than a Nail-Tip heat-fusion bond.
Do not assume rebonds are suitable simply because both methods use individual strands.
Can Rebonds Be Used on Tape-In Extensions?
No.
Tape-In extensions use adhesive panels rather than individual keratin fusion bonds.
Can Rebonds Be Used on Hair Wefts?
Not for normal Hair Weft installation.
Hair Wefts use completely different professional fitting systems.
Can Rebonds Be Used on Loose Extension Hair?
Potentially, where the loose extension hair is suitable for professional pre-bonded preparation and the fitter is trained in the technique being used.
How Do You Remove Old Keratin Before Rebonding?
Suitable extension strands should first be professionally removed from the client's natural hair using the correct removal method.
Remaining old keratin and residue then needs to be carefully removed from the extension strand before a new bond is created.
Should Old Keratin Simply Be Reheated?
Do not assume an old worn attachment should simply be reheated and reused.
The attachment and extension strand should be professionally assessed and correctly prepared before reapplication.
How Are Nail-Tip Extensions Professionally Removed?
Compatible keratin attachments are normally broken down using suitable professional removal pliers and an appropriate bond remover.
The extension should only be released once the attachment has sufficiently broken down.
Should You Pull a Keratin Bond from the Hair?
No.
A fitted keratin attachment should never be forcibly pulled away from the natural hair.
What If a Keratin Bond Will Not Release?
Continue the appropriate professional breakdown process rather than increasing the amount of pulling.
The attachment may require further cracking, remover or working according to the specific bond-removal system being used.
Read Our Nail-Tip / U-Tip Removal Guide
Why Is There Shed Hair Around an Old Keratin Bond?
Natural hair continues its normal growth and shedding cycle while extensions are fitted.
Some naturally released hairs remain held inside the attachment until professional removal.
Does Shed Hair Mean the Extensions Damaged the Natural Hair?
Not automatically.
Normal naturally shed hairs can accumulate around fitted attachments.
However, short snapped hairs, progressive thinning or visible damage are different and should be professionally assessed.
Should Extension Hair Be Clean Before Re-Tipping?
The extension strand should be appropriately prepared and free from residue around the area where the new attachment is being created.
The exact preparation process depends on the previous attachment and professional method.
Can Product Residue Affect Rebonding?
Potentially.
Residue around the attachment area may interfere with clean preparation and bond formation.
Can Oil Be Used Around a New Keratin Attachment?
When the extension is later fitted, heavy oils and conditioners are generally best concentrated away from keratin attachment areas unless specific product guidance states otherwise.
Can Rebonded Extensions Be Washed Normally?
Once professionally fitted, follow the normal method-specific aftercare for pre-bonded Nail-Tip / U-Tip extensions.
Wash carefully around fitted attachments and concentrate conditioner mainly through the mid-lengths and ends.
Can Rebonded Extensions Be Heat Styled?
Human hair extension lengths can generally be heat styled where appropriate, using suitable heat protection.
Keep straighteners, curling tools and concentrated styling heat away from fitted keratin bonds.
Can You Sleep with Rebonded Nail-Tip Extensions?
Yes, once they have been professionally fitted as Nail-Tip extensions.
Make sure the hair and root attachment areas are dry before bed, gently brush the lengths and loosely secure longer hair where appropriate.
Can You Swim with Rebonded Nail-Tip Extensions?
Fitted Nail-Tip extensions can generally remain in place while swimming, but chlorine, salt water and repeated soaking can affect extension condition and colour.
Rinse thoroughly afterwards and dry the root and bond areas properly.
Can Keratin Rebond Colour Fade?
The appearance of the attachment may change through wear, product exposure and general use.
The extension hair itself may also change colour independently of the attachment.
How Do You Know When Extension Hair Should Not Be Rebonded Again?
Consider replacement rather than further rebonding if the extension hair has become:
- Excessively dry
- Very thin
- Severely tangled
- Heavily heat damaged
- Structurally damaged near the tip
- Significantly deteriorated through repeated wear
Can Keratin Rebonds Save Reusable Extension Hair?
They can allow suitable extension hair to be prepared with a fresh attachment where professional assessment shows that the hair remains appropriate for reuse.
That does not mean every old extension strand should automatically be reused.
Are Clear Rebonds Better Than Coloured Rebonds?
No.
The different colours serve different attachment and aesthetic requirements.
The professional should select the option most appropriate for the hair and fitting being carried out.
Are Black Rebonds Stronger Than Clear Rebonds?
Colour should not be treated as an indicator of attachment strength.
Select the rebond according to compatibility and desired appearance rather than assuming one colour performs better.
Can Different Rebond Colours Be Used in One Fitting?
Potentially.
If a client's hair contains significantly different colour areas, the professional may choose different attachment colours where appropriate.
How Should Unused Keratin Rebonds Be Stored?
Keep them clean, dry and appropriately stored away from unnecessary heat, contamination and moisture until required.
Who Should Use Keratin Rebonds?
They are intended for professionals familiar with:
- Pre-bonded extension preparation
- Heat-fusion equipment
- Keratin attachment formation
- Natural-hair sectioning
- Extension weight and placement
- Professional removal

Final Thoughts
Keratin Rebonds provide a practical professional option when suitable extension hair needs a fresh pre-bonded attachment before reapplication.
Rather than discarding suitable extension hair solely because the original keratin attachment has been removed, a trained professional can assess the strand, prepare it correctly and create a fresh compatible bond where appropriate.
HairX Keratin Rebonds are supplied as convenient pre-shaped pieces in Clear, Amber, Brown and Black, with approximately 100 pieces per pack.
The rebond colour, amount of bonding material, extension condition, heat control and finished attachment size all need to be considered carefully. More keratin or more heat does not automatically produce a better bond.
Most importantly, rebonding should only be carried out on extension hair that remains in suitable condition and with products, tools and techniques compatible with the extension system being prepared.
