What Are Fusion Hair Extensions?

Fusion hair extensions (also referred to as keratin or pre-bonded extensions) are semi-permanent extensions that are impossibly lightweight and unbelievably undetectable, making them a top-notch option for ladies that want thick, full, and luscious manes.

How Are Fusion Hair Extensions Applied?

Fusion hair extensions are applied in strands rather than typical wefts. The strands are infused with keratin and are pre-bonded, which means they contain the necessary glue – no additional product is required. 

To apply the fusion hair extensions, the stylist will need to section your locks into small portions. They will place the extensions near a few strands of your natural hair, close to the root. Then, they will use a unique tool – a fusion hair iron – to melt the u-tip extension into your mane. 

By melting the product, the stylist creates a strong bond that is not clunky and lasts an impressively long time.

Pros and Cons of Fusion Hair Extensions

Are fusion hair extensions suitable for you? To help you make the right decision, I’ve included some must-know pros and cons of these hair extensions. Let’s dive in!

Pros of Fusion Hair Extensions

There are many pros associated with fusion hair extensions. So much so that you might find that they’re genuinely a “unicorn” in the hair care biz. 

  • They’re long-lasting (up to three months or more)

While other extension options, such as tape-ins and micro-rings, can deteriorate in as little as two months, fusion hair extensions can easily last up to three months or longer. It really depends on how well you take care of your extensions and their quality.

  • Blend seamlessly

When it comes to disguising hair extensions, some options are pretty tricky (we’re looking at you, clip-in hair extensions!). 

Fusions, on the other hand? Since they’re bonded to the hair strands, they’re hardly noticeable. You can wear your hair however you want without fear of your extensions showing. This gives you ultimate hairstyling freedom and peace of mind!

  • Very lightweight

Nobody likes to feel like they’re wearing a mop on their head or that their extensions are tugging their natural strands in every direction. Well, fusion hair extensions do neither. They’re incredibly lightweight – you might even forget they’re in your head!

  • Great for all hair types

Some hair extensions aren’t suitable for everyone, but fusion hair extensions are. Whether you have a thin and straight mane or have a bouncy, thick head of hair, fusion hair extensions can work with your hair type.

  • They’re safe and effective

One of the biggest perks is that they’re entirely safe and effective. The extension is designed with keratin glue, a hypoallergenic material that can be used near even the most sensitive scalps without worry. And, since your hair is mainly made up of keratin, it won’t damage your mane.

Cons of Fusion Hair Extensions

Although there is a lot to love about fusion hair extensions, it’s not all glamorous! Here are some of the drawbacks to consider before taking the plunge.

  • Application takes a while

Since fusion hair extensions are strands and not wefts, they take longer to apply. While application time will vary depending on the experience of your hairstylist and the number of extensions, you should expect the application to take three hours or longer.

  • Requires professional application

Don’t try to cut corners or shorten the time frame by applying yourself! While there’s no rule saying you can’t apply fusion hair extensions on your own, you will run the risk of damaging your natural hair and/or scalp. Leave it to the professionals, queen.

  • Must be used with care

This isn’t much different from any other hair extension type, but it’s still worth noting. You won’t want to be rough with these beauties or use excessive hot tools, especially near the root of your mane, as this can hinder the glue’s effectiveness. 


At this point, you probably know if fusion hair extensions are right for you. But why stop there? Here are a few more questions to ask yourself before calling your hairstylist!

Are fusion extensions damaging?

Fusion hair extensions are not damaging, which is one of their most significant advantages. However, that doesn’t mean they can’t cause damage. If you apply them or try to remove them on your own, you can cause significant damage. Avoid this by opting for a professional!

How much does it cost to install fusion hair extensions?

Every hair stylist will charge a different amount. However, the typical going rate is around $500 plus the cost of the hair, which is typically about $200. So, you’re looking at about $700 (but no more than $1,000, in most cases).

Can you wear your hair up with fusion extensions?

You can wear your hair however you want with fusion extensions; in fact, that’s another one of their perks! With fusion hair extensions, you’re given absolute freedom to style your locks without the fear of clips, tape, or other “common” extension pieces playing peek-a-boo.

How do you wash your hair with fusion extensions?

When washing your fusion hair extensions, it’s best to use a natural shampoo (no sulfates!) and to be very gentle. Roughly scrubbing your scalp and mane can have a negative impact on the longevity of your fusion hair extensions. Follow up with some conditioner for superb glossiness!

Fusion Hair Extensions Are Some of the Best in the Biz!

When it comes to hair extensions, it’s clear that fusions are some of the best in the hair business. They’re long-lasting, lightweight, and undetectable, making them a superior option to consider. Just keep in mind that they must be installed by a professional, and the appointment isn’t cheap and will likely take longer than three hours.
