You have probably heard how Fusion Hair Extensions are the secret of the catwalk and red carpet looks from Milan to Hollywood. However, they are fast becoming the secret weapon of women everywhere. Traditional hair extension methods damage the natural hair and can be seen by the naked eye. They were heavy and limited the ways you could style your hair. All things considered, fusion hair extensions are a game changer. This guide will explain everything you need to know to decide if you want to take the plunge and become the best version of yourself.

We will cover everything from how much they cost to the best way to make them last and how to take care of your investment in yourself. So read on for an insider's guide to fusion hair extensions!

What are fusion hair extensions?

Fusion air extensions are also known as keratin bonds or pre-bonded extensions. You might also hear them called I-Tips, U-Tips, or keratin fusion extensions. Unlike traditional hair extensions, general fusion hair extensions come in stands instead of wider wefts. In addition, they are premade with keratin at the top of each strand. Keratin is a natural strengthening protein in hair that adheres to your hair better, creating less damage than traditional methods.

Hair extensions are attached with a heating element to fuse the keratin bond to the hair in hot fusion hair installations. With cold fusion extensions, the hair is attached using a bead which is clamped down to hold the bond in place. This method is considered to be safer for the hair as there is no heat involved.

Since human hair is 95% keratin, the fusion method is not as damaging to the natural hair as traditional hair extensions that use other glues.

What are the different types of fusion methods?


I-tip extensions have pointy or needle-shaped tips that are best for those with thinner hair as it doesn't cause pressure at the roots and they blend in easily with your natural hair, even if it's thinner. I-tip hair extensions are great for adding volume to your hair in a natural-looking way. In addition, the keratin-tipped end can be used for hot glue and cold fusion installations.


U tip extensions, also known as flat tips, are better suited for healthy, thicker hair. The bonding area is more extensive and tends to last longer for this reason. U-Tipped hair extensions have a curved fingernail-like end that wraps around your natural hair strands. They are attached by heating up the keratin glue and folding it around your own hair strand.

In addition, U- tip extensions are more resilient than I-tips. However, I-tips are more popular because of their flexibility and ease-of-use. For a more in-depth guide on the differences between i-tips and u-tips, click here.

Beaded Wefts

The beaded weft method can be considered a hybrid of the sew-in method and fusion hair extensions. Beaded wefts are fusion hair extensions that come in a long, continuous strip with small beads already attached. The beads are then clamped down onto the natural hair using pliers to secure them in place.

Are fusion hair extensions safe?

Even though heat is used to bond keratin to your hair, the process is very safe in the hands of a professional. The extensions are smaller and spread evenly over your head, so don't create as much weight or pressure on one point. In addition, the keratin bond is a naturally occurring substance and is less prone to causing allergic reactions. Also, if improperly applied, fusion extensions can damage your own hair and scalp. There have been cases of people losing patches of their hair or experiencing scalp burns from fusion extensions. Therefore, it is important to only have fusion extensions installed by a professional stylist who has experience with this method.

Will fusion hair extensions damage my hair?

Most beauty treatments like hair dye and perms will slightly damage the condition of your hair. Fusion hair extensions are not any different and will create a small amount of stress on the hair where it is bonded, but it is much less than traditional weft extensions. Fusion hair extensions are lighter, and the keratin is more gentle and natural than the traditional glues. In addition, the fusion keratin bond is more flexible. All of these things create less damage to your natural hair.

How long do fusion hair extensions last?

These extensions last 3 to 5 months, depending on how you treat them. If you use a special brush, only wash your hair every few days, and don't overdo the styling with heated tools, it will last much longer. 

They will have a much shorter life span if you swim a lot or wash your hair every day. It also depends on how fast your hair grows and how often you have your hair cut.

What hair types are they suitable for?

Every hair type can benefit from general fusion hair extensions. They come in every texture imaginable to suit every hair type and wave pattern. But are they better for thin hair or thick hair?

You should have at least 5 inches of hair to start with, and if your hair is significantly damaged, it is better to wait until it is in better condition.


Fusion hair extensions are lightweight and look natural when added to fine hair textures. In addition, they can thicken and add fullness to fine hair since they are not as heavy, and people report less irritation from fusion hair extensions.

Thin Hair:

Since the extension bond is almost invisible, you can have the extensions added around the face and hairline, adding volume everywhere and not just length. The bond is so natural and hard to see that this is an excellent option for people with thinning hair. The cold fusion method is better as the bond is even harder to see.

For Color Changes

With so many different shades and no limit on placement, you can get the effect of added highlights or lowlights without resorting to chemicals and dying the hair.

Short Hair

Fusion hair extensions come in every length and are suitable for even shorter hairstyles where more volume is desired. The hair lengths now available make getting extensions on shorter hair a viable option!

Curly or Wavy hair

There are almost no limits to wave and curl patterns available to match any texture!

Are tape-ins better than fusion hair?

Both methods have their own advantages and disadvantages, so it is important to consider your needs before making a decision. Fusion extensions are bonded to the natural hair using heat, making them very durable. However, they can be difficult to remove and may cause damage to the natural hair. Tape-in extensions, on the other hand, are attached using a special adhesive tape. They are much easier to remove than fusion extensions, but they may not stay in place as well for people with oily skin or fine hair. Ultimately, the best choice for you will depend on your individual needs and preferences.

What's the best type of human hair for fusion extensions?

Natural human hair is the best type of hair to use because real hair behaves just like your natural hair when you style it. Some of the many reasons natural hair is better than synthetic are:

  • It doesn't tangle as easily.
  • Frizz-free.
  • Looks more natural.
  • It takes and holds styling better.
  • Lasts longer.

Some of the types of natural hair extensions that you can buy are as follows: Slavic hair: This is the best choice for you if your hair is fine and soft. This premium quality hair usually comes from one donor. Russian hair: If you color your hair or it is a medium weight, you can use Russian hair. Indian hair: For really thick dark hair and curly styles, we recommend Indian hair. The installation of general fusion hair extensions.

There are two types of Fusion Hair Extension installation. One is called hot fusion hair extensions and is done with a heating element that melts the keratin and bonds it to the hair. This method is becoming slightly outdated as there are more efficient methods now available, but it is still a popular option among experienced hair stylists around the world. 

Cold fusion uses beads that are clamped onto the hair with no heat. These fusion extensions are more gentle on the hair and scalp. Cold fusion is sometimes referred to as MicroLink extensions.

How much hair do I need for an installation?

Keratin Fusion bundles contain 25 individual strands; for a full head installation, you usually need 5 to 6 bundles or more depending n the look you're after. For a partial installation, you usually need between 3 to 4 bundles.

Don’t forget when considering the cost to consider the upkeep. You will have to come in every three months or so for rebonding and reapplication, also known as touch-ups, which takes as much time as the initial appointment.

Taking into account the expense and extra time taking proper care of them, I would still say that general fusion hair extensions are worth it. 

As women, our hair is our crowning glory. So, whether you want extensions for a special occasion or just to boost your confidence, we would say it is worth it.

What is the cost of Fusion Hair Extensions?

As well as varying from salon to salon, the cost of your extensions depends on how many strands you need, how long the strands are, and what quality the hair extension is. Fusion hair extensions will give you a natural-looking yet stunning head of hair, but they are not inexpensive. Fusions extension can cost anywhere between $300 - $1000 plus the cost of the hair, which is roughly $200. And they have to be reset at the hairdresser every three months. Cold-fusion hair extensions last longer and are even better for your hair. However, these can cost between $1200 - $3000. Cost can vary greatly depending on your area and stylist.

Is fusion hair the right method for me?

Fusion hair extensions are a great way to add length and volume, but they may not be the best method for everyone. If you have any concerns about your scalp or hair, fusion extensions may not be right for you. Talk to your stylist about what will work best for you and your lifestyle. They may recommend tape-in hair extensions or another method that suits you better.

Can I do my own Fusion Hair Extensions?

While it is possible to do it yourself, we don't recommend it as a professional stylist can assess your hair to see what type and amount will give you the best results. They can also ensure that they attach the bond in the correct place and pattern to provide you with the best results. In addition, it is easy to burn yourself or place the extensions unevenly when you are not trained.

What tools are needed to install Fusion Hair Extensions?

If you are a professional stylist or have the know-how to install fusion hair extensions at home, you will find the following tools a big help:

  • Hot fusion protector shields
  • Ridged hair extension pliers
  • Glue Sticks
  • Keratin fusion glue pebbles
  • Fusion Hot Pot
  • Pulling Loop Needle
  • Fusion Hair Extension Iron

How long does it take to install fusion hair extensions?

Depending on the number of strands you need to be installed, it can take anywhere from three to six hours. Getting them taken out can take just as long! We suggest bringing a few good magazines and your earbuds!

What is the removal process of fusion hair?

Hot fusion hair extension removal is a long process that involves breaking down the keratin glue bond with a specially formulated bond remover and then gently sliding the hair extension off of the natural hair. If this is done correctly, it should not damage the natural hair.

The removal of cold fusion with beads involves gently sliding the bead off of the natural hair. The fusion hair extension can then be slid out of the bead. It is always best to have fusion extensions removed by a professional in order to avoid any damage to your natural hair. 

Caring for your fusion hair extensions

You're going to be so excited when you see what a significant difference fusion hair extensions make to your look. However, be prepared for a bit of discomfort for the first few days after getting your installation. You will have to get used to the extra weight, and they may pull or irritate your scalp at first. Don't wash your hair for at least 72 hours to let the bond set. Also, fusion hair extensions require you to be proactive with maintenance and proper care, more so than other hair extension methods.

Before sleeping:

It is a good idea to put your hair in a high ponytail, pigtails, or a braid before you go to bed. This will keep you from pulling on the extensions in your sleep and help keep your extensions from tangling.

Heat styling tools:

The most important thing to remember is that heat can loosen the bonds, so avoid blow dryers and curlers. If you must use them, put a thermal spray protectant first and avoid direct heat on the bonds. The less you pull on the bonds, the longer they will last, but you can otherwise style as usual. You will need to be careful with flat irons and curling irons as excessive heat can loosen the bonds.


Be sure to use a paddle brush or wide-tooth comb to avoid damaging the bonds. Gently brush your hair from the bottom up, starting with your ends. You may find that it is helpful to detangle your hair while it is still wet.

Shampooing and Conditioning:

You can shampoo and condition your fusion hair extensions just like you would your natural hair. Be sure to use products that are sulfate-free and avoid any harsh chemicals. When conditioning, apply the conditioner to the ends of your hair first and work up. Try to avoid getting the conditioner on the bonds as this can cause them to loosen.


Don't wash your hair every day or scrub your scalp. Wash it gently, and don't put shampoo or conditioner directly on the bonds. Instead, use a special hair extension brush to get rid of tangles. Don't fall asleep with your hair wet.


Avoid chlorine and bleach. In other words, swimming pools and bleaching your hair should be avoided. Instead, use a nourishing and gentle shampoo and avoid using oil-based products to break down the keratin glue bond.
