Difference Between Keratin, Rebonding, and Extenso

Does your hair need a transformation, but you don’t know where to start? Do terms like Keratin, Rebonding, and Extenso seem a little confusing? Don’t worry — we are here to break it all down for you! Understanding the different hair treatment services available on the market can be complicated and intimidating, but with a little bit of knowledge, you can make an informed decision. This blog post will discuss the difference between keratin, rebonding, and extenso to help guide your decision-making process. Continue reading to learn more about these three processes.


Keratin treatments are designed to smooth and soften your hair while also adding a bit of shine. The process is semi-permanent and can last up to three months, depending on hair type and maintenance.

The treatment works by coating the hair with a protein-based solution, which helps seal each strand’s cuticle layer. This helps to reduce frizz and make the hair look smoother and more manageable. The keratin treatment is best for those with wavy or curly hair.

Our hair naturally contains keratin, but it can be damaged or depleted over time. Therefore, a keratin treatment is designed to help replenish the natural protein in your hair. If you’re looking for a treatment that will help your hair look smoother and softer without any major changes, a keratin treatment is a way to go.


Rebonding is a more intense hair treatment process involving using chemicals to straighten your hair permanently. This technique works by breaking the disulfide bonds in the hair and then reforming them to create a straight finish. This process is best for those with naturally curly or wavy hair, as it will help create a smooth and sleek look.

The results of rebonding can last up to 6 months to one year. However, this may vary depending on how well you take care of your hair. It’s important to note that this process is not recommended for those with severely damaged hair, as the chemicals used can cause further damage.

People with thick, coarse, or curly hair will benefit the most from this treatment. Your hair will be left looking extremely straight and glossy, but it’s essential to take note of the maintenance required if you want to keep your hair looking good for longer.


When you’re looking for a dramatic change, Extenso is the best option for you. It’s similar to rebounding, using chemicals to permanently restructure your hair’s shape. However, Extenso is more intense as it helps to create curls and waves in addition to straightening.

With this technique, you can get anything from subtle waves to tight ringlets depending on your desired look. This treatment is best for those with naturally straight hair as it can help to create beautiful, voluminous curls.

Like rebounding, the results of this treatment can last up to 6-8 months. However, this may vary depending on hair type. Extenso can be used on all hair types. However, it is important to note that this technique is not reversible.

Keratin vs. Rebonding vs Extenso

1. Duration

Keratin lasts up to 3 months, while rebonding and extenso can last up to 6-8 months. The duration may vary depending on hair type and maintenance. Hair treatments should be repeated after a certain period of time in order to maintain the desired results.

If you’re looking for a semi-permanent solution, keratin is the best option. If you’re looking for something, more permanent, rebonding or extension is the way to go.

2. Hair Types

Keratin treatments are best for those with less wavy and weak hair. Rebonding is best for those with thick, coarse, or curly hair. People who do not want volume or curls but a straight finish should go for rebonding.

Extenso is best for those wishing for straight hair but with a natural volume. People with naturally straight hair who want to add curls or waves should go for extenso.

3. Results

Rebonding and extenso are more dramatic, as they help to create a permanent change in the hair. The results of these treatments will last for a more extended period of time as compared to keratin, but it’s crucial to maintain the hair with good haircare products.

Keratin is more subtle and helps to replenish the hair with natural protein. The results are usually softer, smoother, shinier, and more manageable.

4. Safety

Keratin treatments are generally considered safe, and the chemicals used in them are mild. Rebonding and extenso treatments use strong chemicals that can cause damage to the hair if not done correctly. It is important to consult with a professional before opting for these treatments, as they can have severe consequences for the hair.

5. Duration of Process

Rebonding takes about 4-5 hours, while extenso takes about 2-3 hours. Keratin treatments are usually done in one session and take around 1-2 hours, depending on the length of the hair. So, if you’re looking for a quick fix, keratin is the best option.

6. Cost

Many of us are conscious of our pocket, so the cost can be a significant deciding factor when choosing between these treatments. Keratin treatments are usually the cheapest, followed by extenso and rebonding being the most expensive. The cost usually depends on the length of the hair, but they all offer great value for money. If you are on a budget, keratin is best for you.

7. Past Hair Condition

You can go for any of the three if you have absolutely virgin hair with no past treatments. However, if you have already had keratin or other hair treatments, it is essential to consult a professional before opting for rebonding or extenso. These treatments can cause serious damage to the previously treated hair, so it is important to be careful.


These treatments offer great value and can help transform your hair in just a few hours. The best treatment for you will depend on your hair type, desired results, and budget constraints. It is essential to do your research before deciding which treatment to go for, as each has pros and cons. Whichever you choose, make sure that it’s done by a professional and that the right after-care products are used. Good luck!
