Will Keratin Treatment Make My Hair Straight? Exploring the Myth and Reality of Keratin Treatment

Hey there! Are you tired of battling your frizzy hair every day? Do you dream of having straight, soft, and manageable hair without having to spend hours in front of the mirror? Well, you might have heard about keratin treatments, and the big question that comes to mind is: will keratin treatment make my hair straight?

Keratin treatments have become a popular choice for people who want to transform their hair into a sleek and smooth look. But before we dive into the magic of keratin treatments, let’s get to know a little bit more about this hair treatment. Keratin treatment is a process where the natural protein in your hair (keratin) is infused with additional keratin to create a protective layer around each hair strand. This layer helps to reduce frizz, add shine, and make your hair more manageable.

Now the big question is, will keratin treatment make my hair straight? The answer is not straightforward. It depends on your hair type, texture, and the final look you are aiming for. Keratin treatment won’t make your hair pin-straight like a flat iron, but it will certainly reduce frizz and unwanted curls to give you a more natural, wavy, or straight look. The more keratin is applied, the straighter the hair will become, but be mindful it is still not a permanent solution, and the results depend on various factors.

Keratin Treatment Process

So, you might be asking, will Keratin treatment make my hair straight? The answer is more complex than a simple yes or no. But first, let’s dive into how Keratin treatments work.

Keratin treatment is a salon treatment that aims to smooth and straighten frizzy or curly hair. It is a chemical process that uses a protein called Keratin to replace the natural protein in your hair. During the treatment, a stylist will apply a formaldehyde-based solution to your hair, which will break the bonds that make your hair curly or frizzy. Then, the stylist will use a flat iron to seal the Keratin into your hair, making it smooth and shiny.

  • The treatment can take anywhere from 90 minutes to 4 hours depending on the length and thickness of your hair.
  • The results can last up to six months, depending on your hair type and how well you maintain your hair.
  • It is recommended that you don’t wash your hair or use any styling products for 72 hours after the treatment.

It’s important to note that not all Keratin treatments are created equal. Some treatments may use formaldehyde-free solutions, which are often labeled as “organic” or “natural” treatments. These treatments may be less effective at straightening your hair but are considered safer, as formaldehyde is a known carcinogen.

Additionally, the effectiveness of Keratin treatments in making your hair straight depends on your hair type. If you have very tight curls, a Keratin treatment may loosen them, but you may still need to use a straightening tool to achieve a completely straight look. If you have wavy or slightly curly hair, a Keratin treatment may be enough to achieve a straight look without additional tools.

Pros Cons
– Can make hair smoother, shinier, and more manageable – Formaldehyde-based solutions can be harmful if inhaled
– Can reduce frizz and curl in most hair types – Can be expensive
– Can last up to six months – Not all treatments are created equal

Overall, a Keratin treatment can be an effective way to make your hair smoother and more manageable. However, it’s important to consider your hair type and the potential risks before getting the treatment. Be sure to do your research and choose a reputable stylist who uses safe and effective solutions.

Hair Straightening Techniques

Hair straightening techniques have evolved over the years with the increasing demand for sleek and smooth hair. Some of these techniques are temporary, while others are more permanent and may require chemical treatments. Let’s take a closer look at two of the most popular hair straightening techniques: keratin treatment and Japanese Straightening.

Keratin Treatment

Keratin treatment is a semi-permanent hair straightening technique that involves applying keratin protein to the hair shaft. The treatment is designed to smooth out the hair’s cuticle, reducing frizz and leaving the hair shiny and sleek. Unlike chemical straightening treatments, keratin treatment doesn’t completely alter the hair’s structure or break down the bonds in the hair shaft. This means that the hair’s natural texture will still be intact but more manageable.

The application process usually involves washing the hair with a clarifying shampoo, blow-drying, and applying the keratin treatment. The hair is then straightened using a flat iron, and the treatment is left on the hair for a few days. During this time, it’s important to avoid washing the hair and tying it up to prevent kinks from forming.

  • Keratin treatment is suitable for all hair types, including chemically relaxed and colored hair.
  • The treatment is designed to last for several months, but the longevity will depend on the hair’s natural texture and how well it’s cared for.
  • Keratin treatment may also improve the hair’s overall health by strengthening and repairing damage.

Japanese Straightening

Japanese Straightening is a more permanent hair straightening technique that originated in Japan. It involves using chemicals to break down the hair’s natural bonds and restructure them in a straight pattern. The process usually involves applying a relaxer to the hair, which is then neutralized to lock in the straightened structure.

This technique is more invasive than keratin treatment and requires a longer application time. It’s also more damaging to the hair, and it can leave it dry and brittle if not done correctly. However, the results are more long-lasting, and the hair will remain straight until it grows out or is cut.

Pros Cons
The results are long-lasting The process is more invasive and damaging to the hair
The hair will be completely straight, with no frizz or curls The hair may become dry and brittle if not done correctly
It’s suitable for those with tightly curled and coarse hair textures The process can take several hours to complete

When choosing a hair straightening technique, it’s important to consider your hair’s natural texture, the level of maintenance you’re willing to undertake, and any potential damage the treatment may cause. With the right technique and proper care, you can achieve the sleek, straight hair you desire.

Difference between Keratin and Chemical Relaxers

Both keratin treatments and chemical relaxers are popular hair straightening methods. However, they have fundamental differences in their composition, application, and effects.

  • Composition: Chemical relaxers are alkaline and contain strong chemicals such as sodium hydroxide or guanidine hydroxide, which break the disulfide bonds of the hair strands, resulting in permanent straightening. In contrast, keratin treatments contain keratin protein, which is a natural component of hair, along with other ingredients such as formaldehyde or glyoxylic acid, which bond the keratin protein to the hair shaft, resulting in semi-permanent straightening.
  • Application: Chemical relaxers are usually applied to the hair roots first and then worked down to the ends. The process involves leaving the chemical on the hair for a specific time, then rinsing it off, and neutralizing it with a neutralizing shampoo. On the other hand, keratin treatments are applied to the hair in sections, and a flat iron is used to seal the protein and other ingredients into the hair strands. The process takes longer than chemical relaxers and requires the hair to avoid water and styling for a few days.
  • Effects: Chemical relaxers result in permanent straightening, with the hair growing out in its natural form. However, the chemicals used can damage the hair, and frequent application can lead to hair breakage, thinning, and scalp irritation. In contrast, keratin treatments offer semi-permanent straightening, with the effects lasting for 2-4 months. The treatment can improve the hair’s texture, shine, and manageability, but it can also cause damage if the hair is over-processed or if the ingredients used are not suitable for the hair type.


Both keratin treatments and chemical relaxers can make the hair straight, but they have different composition, application, and effects. It is essential to understand the differences and consult with a professional stylist to determine which method is suitable for your hair type and desired outcome. Moreover, it is vital to follow the aftercare instructions and use the recommended products to maintain healthy, shiny, and straight hair.

If you’re looking for a long-lasting solution, then chemical relaxers may be the right choice for you. But if you want to improve your hair texture and manageability without damaging your hair, then keratin treatments can be a great option. Remember, your hair is your crown, and it deserves the best care.

Chemical Relaxers Keratin treatments
Contain strong chemicals Contain keratin protein
Straighten hair permanently Straighten hair semi-permanently
Can damage hair and scalp Can improve hair texture and shine

Ultimately, the decision between chemical relaxers and keratin treatments depends on your hair goals, concerns, and preferences. Always consult with a professional stylist and educate yourself about the products and ingredients used in your hair care regimen.

Benefits of Keratin Treatment

Keratin treatment is a popular hair treatment that has been gaining a lot of attention in recent years. This treatment involves applying a keratin-based solution to the hair, which helps to smooth out the hair cuticle, making it softer, shinier, and more manageable. The benefits of keratin treatment are numerous, with the most common ones being:

1. Frizz Reduction: Keratin treatment is known for its ability to reduce frizz in the hair. This makes it an excellent treatment for people with curly hair or those living in humid environments. The treatment helps to smooth out the hair cuticle, making it less susceptible to frizz caused by humidity and heat.

2. Hair Straightening: While keratin treatment does not straighten the hair completely, it does help to relax the curls, making the hair appear straighter. This is an excellent option for people who want to reduce the curl in their hair but do not want to commit to chemical straightening treatments.

3. Hair Strengthening: The keratin used in the treatment is a protein that is naturally found in hair and nails. When applied to the hair, it helps to strengthen and repair the hair shaft. This makes the hair less prone to breakage and split ends, resulting in healthier-looking hair.

Benefits of Keratin Treatment: Maintenance

4. Low Maintenance: One of the best things about keratin treatment is that it is low maintenance. Once you have had the treatment done, you do not have to worry about spending a lot of time styling your hair. The treatment helps to make your hair more manageable, which means that you can easily style it with minimal effort.

  • Unlike chemical treatments, keratin treatment is not permanent. It typically lasts for 3-4 months, which means that you will need to have the treatment done on a regular basis to maintain the results.
  • However, even after the treatment has worn off, your hair will still be softer, shinier, and easier to manage than it was before the treatment.
  • Additionally, because the treatment helps to reduce frizz, you will find that you do not have to spend as much time blow drying or flat ironing your hair. This makes keratin treatment an excellent option for people with busy lifestyles who do not have a lot of time to spend on their hair.

If you are looking for a hair treatment that will make your hair more manageable, reduce frizz, and make it look healthier, then keratin treatment is an excellent option. With regular maintenance, you can enjoy the benefits of this treatment for months to come.

Keratin Treatment Side Effects

While keratin treatments are a popular option for many people looking to straighten their hair, it’s important to consider the potential side effects that may come with the treatment. Here are some of the most common side effects associated with keratin treatments:

  • Hair loss: Some people report experiencing hair loss or breakage after a keratin treatment. This is typically the result of excessive heat being applied during the treatment or the use of harsh chemicals in the process.
  • Scalp irritation: Burning or itching sensations on the scalp are another common side effect of keratin treatments. This can be caused by the chemicals used in the treatment or the high heat that is applied to the hair.
  • Allergic reactions: In rare cases, people may have an allergic reaction to one or more of the ingredients used in a keratin treatment. This can lead to symptoms like hives, itching, and difficulty breathing.

How to Minimize Side Effects

While there’s no way to completely eliminate the risk of side effects associated with keratin treatments, there are steps you can take to minimize your chances of experiencing them:

  • Choose a reputable salon: Look for a salon that has experience with keratin treatments and uses high-quality products to minimize the risk of side effects.
  • Be wary of at-home treatments: While it may be tempting to try an at-home keratin treatment to save money, these products can be dangerous if not used correctly. It’s best to leave the treatment to the professionals.
  • Follow the after-care instructions: To minimize the risk of side effects, it’s important to follow the instructions provided by your stylist after your keratin treatment. This may include avoiding certain products or activities for a period of time.

Comparison to Other Hair-Straightening Methods

While keratin treatments are a popular option for people looking to straighten their hair, there are other methods that may be safer or more effective:

Method Pros Cons
Japanese Thermal Straightening Results are long-lasting; less damaging than keratin treatments. Expensive; requires touch-ups every 6-8 months.
Chemical Relaxers Results are permanent; relatively inexpensive. Can be damaging to hair; may cause scalp irritation.
Blowouts Easily accessible; less expensive than other options. Results are temporary; can be time-consuming.

Ultimately, the best hair-straightening method for you will depend on your individual hair type and budget. Be sure to talk to your stylist about your options and the potential risks and benefits of each method.

Maintaining Keratin Treated Hair

After investing time and money into a keratin treatment, you want to make sure your hair stays healthy and glossy for as long as possible. Here are some tips on how to maintain your keratin treated hair:

  • Wait before washing: It’s crucial to wait before washing your hair after a keratin treatment. Avoid washing your hair for at least three days to allow the keratin to settle into your hair.
  • Use sulfate-free products: Sulfates are known to strip the hair of its natural oils and shorten the lifespan of a keratin treatment. Therefore, ensure that you use sulfate-free shampoos and conditioners to keep your hair healthy and prolong the effects of the treatment.
  • Avoid tying your hair: Tying your hair in a tight ponytail or bun can also shorten the longevity of the treatment. So, if you must tie your hair, opt for a loose hairstyle that won’t cause tension on your hair.

In addition to the tips discussed above, there are other things you can do to maintain your keratin-treated hair:

  • Avoid chlorine and saltwater: Chlorine and saltwater can be very harsh and dry out your hair. Therefore, avoid swimming in pools and oceans, or wear a swimming cap if you have to.
  • Avoid subjecting your hair to heat: Heat styling tools such as flat irons and blow dryers can also shorten the lifespan of a keratin treatment. Avoid using these tools as much as possible and if you must use them, ensure that you use a heat protectant spray.
  • Trim your hair regularly: Trimming your hair regularly will help get rid of split ends, which can dull the look of your hair. It’s advisable to trim your hair every six to eight weeks.

Products to Use on Keratin Treated Hair

Using the right products on your keratin treated hair is another critical aspect of maintaining the treatment. Here are some hair care products that you should include in your hair care routine:

Product Benefit
Keratin-infused shampoos To keep your hair smooth, shiny, and healthy.
Conditioners To add moisture to your hair and prevent dryness and breakage.
Leave-in conditioners To give your hair extra moisture and protect it from environmental factors.
Heat protectant sprays To prevent heat damage and prolong the lifespan of your keratin treatment.

Using these products will help you keep your keratin treated hair looking great for longer periods.
