What is the difference between Keratin hair extensions and other types of extensions?

April 25, 2022Feb 22, 2024

Keratin hair extensions and other types of hair extensions are popular choices for adding length, volume, and thickness to natural hair. However, there are significant differences between the two types of extensions. In this article, we will explore what keratin hair extensions are, how they differ from other types of extensions, and the various pros and cons of each.

Keratin hair extensions, also known as fusion extensions, are made from 100% natural human hair that has been treated with a keratin protein coating. The keratin coating on the hair allows for a strong bond between the extension and the natural hair. This bond is created through the use of a specialized heating tool which melts the keratin onto the natural strands of hair. This results in a seamless and natural look, making it difficult to detect that the individual is wearing extensions.

On the other hand, other types of hair extensions, such as clip-ins, tape-ins, and sew-ins, use different methods to attach the extensions to the natural hair. For instance, clip-ins use small clips to secure the extensions, tape-ins use medical-grade adhesive tape to bond the extensions to the hair, and sew-ins involve braiding the extensions into the natural hair. These methods tend to be less permanent and require more maintenance as they need to be removed and reattached, either daily or every few weeks.

Now, let’s explore the main differences between keratin hair extensions and other types of extensions.

Installation Process:

As mentioned earlier, keratin hair extensions are installed using a heating tool that melts the keratin onto the natural hair. This process takes approximately 4-6 hours, depending on the amount of hair being attached. On the other hand, other types of extensions usually require less time for installation, ranging from 30 minutes to 2 hours. This makes them a more suitable option for individuals who are looking for a temporary and less time-consuming option.


Keratin hair extensions require minimal maintenance as the bond is strong and durable, lasting for 3-4 months. They can be washed, blow-dried, and styled like natural hair without causing any damage. Other types of extensions, especially clip-ins, require frequent maintenance, such as daily removal and reattachment, or reinstallation every few weeks. This can be time-consuming and may cause damage to the natural hair if not done correctly.

Comfort and Versatility:

Keratin hair extensions are often considered the most comfortable and versatile type of extensions. The keratin bonds are flat and smooth, making them virtually undetectable and comfortable to wear. They also allow for various styling options, such as updos and ponytails, without revealing the extensions. Other types of extensions, especially clip-ins and tape-ins, can cause discomfort and may limit certain hairstyles due to the bulky attachment points.

Damage to Natural Hair:

One of the main concerns with any type of hair extension is the potential damage it can cause to natural hair. Keratin extensions, when installed and cared for correctly, do not cause any significant damage to natural hair. The keratin bonds are gentle on the hair and do not pull or tug on the natural strands. Other types of extensions, especially clip-ins and sew-ins, can cause tension and pulling on the natural hair, resulting in breakage and damage over time.


Keratin hair extensions tend to be more expensive than other types of extensions due to the high-quality human hair and the specialized installation process. Other types of extensions, such as clip-ins and sew-ins, are more affordable as they can be reused multiple times. However, the cost of maintenance and possible damage to natural hair should also be considered when comparing the overall cost of different types of extensions.

keratin hair extensions and other types of hair extensions have significant differences in their installation process, maintenance, comfort, potential damage to natural hair, and cost. It ultimately boils down to personal preference, budget, and desired results when choosing between the two options. Keratin hair extensions are a great choice for those looking for a more permanent and natural-looking option, while other types of extensions are more suitable for individuals who prefer a temporary and budget-friendly solution. Whatever the decision may be, proper installation and maintenance techniques are critical for the longevity of both keratin hair extensions and other types of extensions.
