Clip-In Hair Extensions Guide: Lengths, Weights, Fitting & Choosing the Right Set
Clip-In Hair Extensions are one of the easiest ways to add temporary length and volume without committing to a professionally fitted extension method.
They can be fitted at home, removed whenever you want and styled for everything from everyday wear to weddings, parties and special occasions.
HairXtensions Clip-In sets are available in a range of lengths, weights and colours, so choosing the right set depends on your natural hair, how much volume you want and the finished look you are trying to achieve.
This guide explains how Clip-In extensions work, how to choose the right length and weight, how to fit them, how to colour match them and how to care for them properly.

What Are Clip-In Hair Extensions?
Clip-In Hair Extensions are temporary extensions made from wefts of hair with small clips attached along the top.
The clips are opened, positioned into sections of your natural hair and then snapped closed to hold the wefts securely in place.
Unlike professionally fitted extensions, Clip-Ins do not stay attached permanently. They can be removed at the end of the day and stored until the next time you want to wear them.
Why Choose Clip-In Hair Extensions?
Clip-Ins are popular because they offer flexibility without long-term commitment.
They can help you:
- Add instant length
- Create more volume
- Make curls and waves look fuller
- Add thickness through the ends
- Change your look for special occasions
- Experiment before choosing fitted extensions
- Remove the extensions whenever you want
Clip-Ins are ideal if you want extra hair only when you need it. They can be worn for a party, wedding or night out and then removed before bed.
How Many Pieces Are in a Clip-In Hair Extension Set?
HairXtensions Clip-In Hair Extensions come as a 7-piece set.
Using several separate wefts allows the hair to be distributed across the head rather than placing all of the extension hair in one large section.
The wider pieces are normally used across the back of the head, while narrower pieces can be positioned around the sides to help create a more balanced blend.
What Lengths Do Clip-In Hair Extensions Come In?
HairXtensions Clip-In sets are available in:
- 14 inches
- 18 inches
- 20 inches
- 22 inches
The right length depends on your current hair, your height and how dramatic you want the transformation to be.
14-Inch Clip-In Hair Extensions
14-inch Clip-Ins are a good option for someone who wants a more subtle increase in length or mainly wants to add thickness.
They can work especially well with shorter or medium-length natural hair where an extremely long extension set would create too much contrast.
18-Inch Clip-In Hair Extensions
18-inch Clip-Ins provide a noticeable increase in length while still creating a versatile everyday finish.
This length can work well for soft waves, curls, half-up styles and fuller straight hair.
20-Inch Clip-In Hair Extensions
20-inch Clip-Ins create a longer transformation and can add plenty of movement through the mid-lengths and ends.
They are a popular option for someone who wants clearly longer hair without moving to the very longest Clip-In length.
22-Inch Clip-In Hair Extensions
22-inch Clip-Ins create the most dramatic length within the HairXtensions Clip-In range.
This length works particularly well for long waves, glamorous curls and full party hairstyles.
The finished length will vary according to your height and where the wefts sit on the head.
How Heavy Are Clip-In Hair Extensions?
The total weight varies according to the length of the set.
HairXtensions Clip-In sets generally range from approximately 80g to 115g depending on length.
Longer sets usually contain more hair because additional density is needed to help maintain fullness through the extra length.
What Clip-In Weight Should I Choose?
The best weight depends on your natural hair and the result you want.
If your goal is mainly extra length, you need enough extension hair to blend the transition between your natural hair and the Clip-Ins.
If your natural hair is thick or blunt through the ends, you may need more volume than someone with finer hair.
Choosing an extremely long but very lightweight set can sometimes make blending more difficult because the natural hair may appear much thicker than the extension ends.
Length vs Weight: Which Matters More?
Both matter.
Length determines how long the finished style appears, while weight affects how much fullness the set provides.
A well-balanced Clip-In set should add enough hair to create a natural transition between the natural hair and extension lengths.
Want mainly volume? Choose a length close to your own hair.
Want noticeable extra length? Choose a longer set with enough weight to blend naturally.
Have thick natural hair? Pay particular attention to overall set weight and blending.
How to Choose the Right Clip-In Hair Extension Length
Before choosing a length, consider:
- Your current natural hair length
- Your height
- How dramatic you want the transformation to be
- Whether you plan to wear the hair straight or curled
- How much volume your natural hair already has
Very long extensions can require more blending if the natural hair is considerably shorter.
Can Clip-In Extensions Be Used Just for Volume?
Yes. You do not need to choose a much longer set.
Clip-Ins can be worn at a similar length to your own hair purely to add thickness through the mid-lengths and ends.
This can be especially useful if your hair is naturally fine or becomes thinner towards the bottom.
How Do You Fit Clip-In Hair Extensions?
Clip-In extensions are designed for temporary at-home fitting.
A typical fitting process is:
- Brush your natural hair and extensions so they are completely detangled.
- Section your natural hair horizontally.
- Open the clips on the first weft.
- Position the weft close to the root without attaching it directly against the scalp.
- Snap the clips closed.
- Release another section of natural hair.
- Repeat the process with the remaining wefts.
- Blend your own hair over the Clip-Ins.
The clips should feel secure without pulling or causing discomfort.
Where Should Clip-In Wefts Be Placed?
The widest wefts are generally positioned across the back of the head, while smaller pieces can be used around the sides.
Placement should allow enough natural hair above each weft to hide the clips.
Avoid placing extensions too close to the hairline where attachments may become visible.
How to Make Clip-In Extensions Look Natural
Good blending is what makes Clip-In extensions look convincing.
Helpful tips include:
- Choose an accurate colour match
- Select enough hair for your natural density
- Position the wefts evenly
- Blend natural hair over the clips
- Style your natural hair and extensions together
- Use soft waves or curls where additional blending is needed
How to Colour Match Clip-In Hair Extensions
Colour matching is one of the most important parts of choosing Clip-Ins.
Compare the extension shade against the mid-lengths and ends of your natural hair rather than only the roots.
This is because the extension hair needs to blend most closely through the lower sections of the hairstyle.
If your hair contains several shades, choose the colour that gives the best overall match.

What If My Hair Is Multi-Tonal?
Many people have naturally highlighted or multi-tonal hair.
If one shade does not appear to match perfectly, look at the overall colour through the lengths rather than focusing on one individual strand.
Styling the extensions with waves can also help different tones blend more naturally because the hair mixes together through the movement.
Can Clip-In Hair Extensions Be Curled?
Human hair Clip-In extensions can generally be curled with suitable care.
Use a suitable heat protection product and the lowest effective temperature.
You can curl the extensions before fitting them or style them together with your natural hair once fitted.
Can Clip-In Extensions Be Straightened?
Yes. Human hair Clip-Ins can generally be straightened carefully.
Always use heat protection and avoid excessive or repeated high temperatures.
For the most natural finish, style your own hair and the Clip-Ins together so the textures match.
Can Clip-In Extensions Be Washed?
Yes, but removable extensions do not normally need washing after every wear.
Wash them when required rather than unnecessarily washing them too frequently.
Use suitable extension shampoo and conditioner and handle the hair gently.
How to Wash Clip-In Hair Extensions
- Remove the extensions from your hair.
- Gently detangle them before washing.
- Use lukewarm water.
- Apply suitable shampoo gently through the hair.
- Rinse thoroughly.
- Condition the lengths and ends.
- Rinse again.
- Allow the extensions to dry completely before storing.
Avoid twisting, scrubbing or aggressively rubbing the wefts together.
Can You Use a Hair Mask on Clip-In Extensions?
Yes. A suitable conditioning mask can be used occasionally if the extensions begin to feel dry.
Concentrate the product through the lengths and ends and rinse thoroughly afterwards.

How Often Should Clip-In Extensions Be Washed?
There is no fixed number of wears between washes.
Wash them when they genuinely need cleaning due to styling-product build-up, dirt or general use.
Washing too frequently can create unnecessary wear, while never washing them can allow product build-up to accumulate.
Can You Sleep in Clip-In Hair Extensions?
No. Clip-In Hair Extensions should be removed before sleeping.
Sleeping in them can create unnecessary pulling, friction and tangling.
Carefully open each clip before removing the wefts rather than pulling them from the hair.
Can You Shower in Clip-In Extensions?
No. Because Clip-Ins are removable, take them out before showering.
This makes it much easier to wash your natural hair properly and reduces unnecessary stress on the clips and weft attachments.
Can You Swim in Clip-In Extensions?
Clip-Ins should be removed before swimming.
There is no need to expose temporary extensions to chlorine, salt water and unnecessary tangling when they can easily be taken out beforehand.
How to Store Clip-In Hair Extensions
Before storing your extensions, make sure they are:
- Completely dry
- Gently detangled
- Free from excessive styling-product build-up
- Stored somewhere clean and protected
A storage pouch can help protect the hair from dust, friction and unnecessary tangling.

Can You Wear Clip-In Extensions Every Day?
Clip-Ins can be worn regularly, but they should still be removed at the end of the day.
Repeatedly clipping extensions into exactly the same small sections of natural hair may create unnecessary tension, so vary placement slightly where appropriate and make sure the set does not feel too heavy.
Clip-In Extensions vs Professionally Fitted Extensions
Clip-Ins and fitted extensions serve different needs.
Temporary, removable and suitable for occasional or flexible wear.
Professionally Fitted Extensions
Nano-Tips, Tape-Ins, Stick-Tips, Nail-Tips and wefts are fitted for longer-term wear and require professional maintenance.
Clip-Ins vs Ponytail Extensions
A full Clip-In set distributes extension hair across several areas of the head to add overall length and volume.
A Ponytail Extension is designed specifically to add length and fullness to an existing ponytail.
If you mainly want a longer ponytail, the dedicated ponytail option may be quicker and simpler.

Clip-Ins vs Clip-In Fringe
A Clip-In Fringe changes the front of the hairstyle, while a full Clip-In extension set adds hair through the lengths.
The two can even be combined for a more complete temporary transformation.

Are Clip-In Extensions Good for Weddings & Parties?
Yes. Clip-Ins are particularly useful for special occasions because they can add extra hair for styles such as:
- Hollywood waves
- Half-up half-down hair
- Long curls
- Braids
- Voluminous straight styles
They can then be removed after the event rather than requiring ongoing professional maintenance.
Are Clip-In Extensions Suitable for Short Hair?
They can be, but blending becomes more important as the difference between the natural hair and extension length increases.
Short, blunt hair may require more extension density and careful placement to create a smooth transition.
Soft waves can often help disguise the join between shorter natural hair and longer extensions.
Are Clip-In Extensions Suitable for Fine Hair?
Fine hair can sometimes wear Clip-Ins successfully, but weight and placement need to be considered carefully.
The set should not feel excessively heavy or pull on small sections of natural hair.
Enough natural hair must also remain above the wefts to conceal the clips.
How Long Do Clip-In Hair Extensions Last?
The usable lifespan depends heavily on how often the extensions are worn and how they are cared for.
Frequent heat styling, washing, brushing and everyday wear will naturally cause the hair to age faster than occasional use.
Good storage and gentle aftercare can help reduce unnecessary wear.
What Should I Look for When Buying Clip-In Extensions?
Before choosing a set, consider:
- Hair type
- Number of pieces
- Overall weight
- Available lengths
- Colour choice
- Clip quality
- How often you plan to wear them
The best set is not simply the longest one available. It needs to work with your natural hair and your intended style.
