What are seamless clip-ins?

Seamless clip-ins are a type of hair extension that provides a more natural, discreet look than traditional clip-in hair extensions. Seamless PU clip-in extensions feature a thin and flexible polyurethane band that can lay flat against your scalp, making them more invisible and more comfortable to wear than traditional clip-ins with bulkier bases. They are designed to blend seamlessly with natural hair, instantly giving the appearance of added volume, length, or both without the obvious signs that you are wearing extensions. That's how they got their names.

The clips used for these extensions are often smaller and lighter, adding to their discreet nature. And Ula Hair seamless clip-ins are made of 100% Remy hair, which also helps to create a natural and stunning look.

Seamless clip-in hair extensions are a popular choice for those who want a temporary and versatile way to change their hairstyle without committing to more permanent methods like sew-in extensions, tape-ins, or fusion extensions.

Pros and cons of seamless clip-in hair extensions

Seamless clip-in hair extensions offer several advantages and disadvantages. Here is a breakdown of the pros and cons to help you decide if they are the right choice for you:


  1. Easy to install and remove: Similar to the classic style, seamless clip-ins are user-friendly and can be installed and removed within a few minutes without professional help, making them a convenient choice for those who want to change their look frequently.
  2. Non-damaging: As they don't require glue, heat, or chemicals for installation, they are less likely to damage your natural hair when used correctly.
  3. Temporary: Being a temporary hair extension method, they allow you to experiment with different styles, colors, and lengths without a long-term commitment.
  4. Cost-effective: Seamless clip-ins are generally more affordable than other hair extensions methods like sew-ins, tape-ins, or fusion extensions.
  5. Discreet and natural: The thin and flexible polyurethane band and smaller clips make them less visible and more natural-looking than traditional clip-in extensions.
  6. Durable: Since the PU strip is glued 7 times during the process, Ula Hair's seamless clip-ins are very robust and you will never need to worry about the hair shed with proper maintenance and installation.
  7. Customizable: You can choose the length, density, and color of the extensions to suit your preferences and style. These extensions can instantly add length and volume to the area you desire.
  8. Comfort: The lightweight design and thin polyurethane band make seamless clip-ins more comfortable to wear than traditional clip-in hair extensions.


  1. Cannot be dyed: The hair of seamless clip-ins can be dyed since it's 100% human hair, but the PU strip can't be colored since it can't absorb the color when you dye the extension. 
  2. More expensive: Although seamless clip-in hair extensions are typically cheaper than sew-in hair extensions, tape-ins, and other hair extension types, they are more expensive than classic-style clip-in hair extensions. However, despite the higher upfront cost, investing in seamless clip-ins can ultimately save money over time since they require less frequent replacement.
  3. Need to be removed before sleeping: Similar to the classic clip-in hair extensions, seamless styles are also recommended to be removed before bedtime to avoid unnecessary hair shed that may be caused by friction and the clips.

By weighing the pros and cons, you can decide if seamless clip-in hair extensions are the right choice for your needs and lifestyle.

Differences between seamless clip-ins and classic clip-ins

Seamless clip-ins and classic clip-ins are both popular types of hair extensions that can add length, volume, or highlights to your natural hair. However, they have some differences in design, application, and feel. Here are the main differences between seamless clip-ins and classic clip-ins:

Attribute Seamless Clip-ins Classic Clip-ins
Design Thin, flexible polyurethane strip with human hair attached Fabric or lace-based strip with hair sewn onto it and clips attached
Construction Lightweight, virtually invisible, and lays flat against the head Slightly bulkier at the roots, more noticeable when applied
Application More secure grip, easy to apply and remove without professional help Less secure grip but still relatively easy application and removal process
Comfort and Feel Lighter, thinner, more comfortable, and blends well with natural hair Heavier, bulkier, and less seamless blending with natural hair
Suitability Ideal for fine or thin hair, suitable for everyday wear or special occasions Versatile for various hair types, suitable for more dramatic hairstyle changes
Price More expensive due to advanced design and seamless appearance More affordable and popular for those on a budget or trying hair extensions for the first time
Versatility Can lay flat, perfectly fit head curve, and look unnoticeable even in an updo Less invisible and versatile in styling, more suitable for those who desire to leave their hair down

Seamless and classic clip-ins have their own advantages and disadvantages. When choosing between the two, consider factors such as your desired look, comfort, and budget.

How to apply seamless clip-ins?

To install seamless clip-ins, simply part your hair where you want to add the extensions, tease the roots slightly for grip, and then attach the clips to your hair close to the roots. You can layer multiple pieces of varying lengths and densities to achieve your desired look.

Here are some steps to apply seamless clip-ins:

Step 1: Prepare your hair

Before applying the clip-ins, ensure your natural hair is clean, dry, and free of tangles. You may also want to straighten your hair to help the extensions blend better.

Step 2: Section your hair

Starting at the nape of your neck, create a horizontal part using a tail comb or your fingers. Clip the rest of your hair up and out of the way.

Step 3: Measure the weft

Hold the clip-in extension up against your head to ensure it's the right length for the section. The weft should be slightly shorter than your sectioned hair width to avoid visibility.

Step 4: Attach the extension

Before attaching the extension, open the clips by gently pressing them to the sides. Place the weft close to the roots of your sectioned hair, making sure it's centered. Press down on the clips to close and secure them. You should feel a slight tug, but it shouldn't be painful.

Step 5: Release the section again

Let down the hair you clipped up, and create another horizontal part about an inch above the first weft. Clip the remaining hair up and out of the way.

Step 6: Repeat the process

Continue measuring, attaching, and securing the wefts as you work your way up your head. You can use larger wefts for the back of your head and smaller ones on the sides to frame your face.

Step 7: Blend the extensions

After all the wefts are in place, let down the rest of your hair. Use a comb, brush, or your fingers to blend your natural hair with the extensions. You can also use a flat iron or curling iron to style your hair and extensions together for a seamless look.

Step 8: Check visibility

Look at your hair from different angles in a mirror to ensure the wefts are invisible. Adjust any clips as needed.

Remember, practice makes perfect. With time and experience, you can apply seamless clip-in hair extensions quickly and effortlessly.

Tips and tricks to maintain clip-in hair extensions

Clip-in hair extensions are an effective way to add length, volume, and versatility to your hairstyle without permanent extensions. To ensure that your clip-in hair extensions stay looking their most impressive and last as long as possible, follow these tips and tricks for proper care and maintenance:

Tip 1: Store properly

When not in use, store your extensions in a cool, dry place, away from direct sunlight. Consider using a storage case, hanger, or even a ziplock bag to protect them from dust and dirt.

Tip 2: Brush gently

Before and after each use, gently brush your extensions with a soft-bristle brush or wide-tooth comb. Start at the ends and work your way up to the clips, being careful not to pull or tug on the hair.

Tip 3: Wash sparingly

Clip-in extensions do not need to be washed as often as your natural hair. Depending on how often you wear them, aim to wash them no more than once every two weeks or when they start to look dull or feel heavy with product buildup.

Tip 4: Use a sulfate-free shampoo and conditioner

When washing your extensions, use a sulfate-free shampoo and hydrating conditioner. Sulfates can strip the hair of natural oils, making it dry and more prone to tangling.

Tip 5: Avoid excessive heat styling

Limit the use of heat styling tools, such as flat irons, curling wands, and hairdryers, on your extensions. Excessive heat can damage hair, causing breakage and a shorter lifespan. If you must use heat, always apply a heat protector beforehand and use the lowest heat setting possible.

Tip 6: Protect yourself from chlorine and saltwater

If you're swimming in a pool or at the beach, remove your clip-in extensions beforehand to avoid damage from chlorine and saltwater. If you must wear them, ensure they're well covered under a swimming cap and rinse them thoroughly as soon as possible after exposure.

Tip 7: Color with caution

If you want to color your extensions, consult a professional hairstylist. Keep in mind that lightening or bleaching can damage the hair, so stick to darker shades or semi-permanent dyes. By the way, the PU strip cannot absorb the color.

Tip 8: Replace clips as needed

Over time, your extensions may become loose or damaged. Replace them as needed to ensure they securely hold your extensions in place.

Tip 9: Be gentle when removing

Take patience when removing clip-in extensions to avoid damaging your hair or the extensions themselves. Gently unclip each weft one at a time and slowly slide them out of your hair.

Tip 10: Regularly trim and layer

To maintain a natural and seamless blend with your own hair, trim and layer your extensions as needed. It's wise to have a professional hairstylist do this for you to achieve the finest results.

By following these tips and tricks, you can extend the lifespan of your clip-in hair extensions and keep them looking pristine for many wears to come.

Seamless clip-in hair FAQs:

Q: Are seamless clip-ins better?

A: Seamless clip-in hair extensions are considered better than traditional clip-in extensions by many people due to their flexible design and natural appearance. However, they can be more expensive than traditional clip-in extensions. If you are looking for a more natural result, choose seamless clip-ins. If you desire a budget-friendly option, the classic style is for you. Ultimately, it's essential to weigh the pros and cons, and consider your desired look and budget when deciding which type of clip-in extensions are best for you.

Q: How long do seamless clip-in extensions last?

A: Generally, good-quality seamless clip-in extensions can last anywhere from 8 to 12 months, or even longer. The lifespan of seamless clip-in hair extensions depends on a few factors, such as the quality of the extensions, how often you wear them, and how well you take care of them. 

Q: How to make seamless clip-ins look more natural?

A: To make seamless clip-in hair extensions look more natural, follow these tips:

  1. Choose the right color and texture: Pick extensions that closely match your natural hair color and texture. This will help the extensions blend in easier with your own hair.
  2. Opt for high-quality extensions: Invest in high-quality clip-ins made of human hair, as they tend to look more natural and can be styled just like your own hair.
  3. Trim and layer the extensions: Have your extensions cut and layered by a professional hairstylist to match your hair's natural shape and style. This will help them blend in seamlessly with your own hair.
  4. Apply them correctly: Part your hair horizontally and apply the extensions starting at the nape of your neck, working your way up. Make sure the clips are firmly attached to your hair and hidden beneath the layers. Space the extensions evenly and avoid attaching them too close to your hairline, as this can make them more visible.
  5. Style your hair and extensions together: Once the clip-ins are in place, style your hair and extensions together. This will help them blend in and create a more natural look. Use a curling iron, flat iron, or any other styling tool to achieve the desired look.
  6. Blend the extensions: Use a wide-tooth comb or brush designed for extensions to gently blend your natural hair with clip-ins. This will help create a seamless appearance.

Q: Are seamless clip-ins good for thin hair?

A: Seamless clip-in hair extensions can be an effective option for people with thin hair, as they are designed to lay flat against the scalp and blend in more naturally with your hair. 

Q: Can I sleep with seamless clip-in extensions on?

A: While it is possible to sleep with seamless clip-in extensions, it is generally not recommended. Sleeping with clip-in extensions can cause discomfort, tangling, matting, and potential damage to both the extensions and your natural hair.

To protect your hair and ensure your extensions' longevity, it's advisable to remove them before sleeping. If you absolutely must sleep with extensions in, consider using a silk or satin pillowcase to minimize friction and potential damage. Additionally, you can braid or tie your hair in a loose, low ponytail to minimize tangling.

Q: Do seamless PU clip-ins damage natural hair?

A: Clip-in extensions are generally considered less damaging than other hair extension methods since they are lightweight and require no glue. However, there are still some factors that may contribute to damage when using seamless PU clip-ins. These factors include incorrect installation, too much hair extension, or lack of proper care. To minimize the risk of damage when using seamless PU clip-ins, follow the proper installation and care instructions we mentioned above, and choose high-quality extensions made of 100% human hair.
