Is Keratin Treatment For Hair Worth It?

Keratin Treatment

In the pursuit of strong and healthy hair, keratin has emerged as a vital protein that plays a crucial role. Found in hair, skin, nails, and other parts of the body, keratin acts as a protective shield while also providing structural support. It is no wonder that keratin treatments and products have gained popularity in the beauty industry. In this comprehensive guide, we will explore the power of keratin, its benefits, and the various methods of incorporating it into your hair care routine.

What is Keratin?

Keratin is a fibrous structural protein that forms the building blocks of hair, nails, feathers, and the outermost layers of the skin. It is known for its remarkable strength and resilience, making it less prone to damage and breakage compared to other types of cells in our body. The composition and structure of keratin can vary, depending on the tissue in which it is found and its function.

There are two main types of keratin: alpha-keratins and beta-keratins. Alpha-keratins are predominantly found in mammals, including humans, and exhibit a fibrous and helical structure. On the other hand, beta-keratins are found in birds and reptiles, characterized by parallel sheets of polypeptide chains. These different types of keratins contribute to the unique properties of various organisms.

The Benefits of Keratin Treatments

Keratin treatments have gained popularity for their ability to transform frizzy and unruly hair into smooth and manageable locks. These semi-permanent hair straightening treatments work by breaking and resealing the bonds in the hair, resulting in straighter and shinier hair. The effects of a keratin treatment can last anywhere from three to six months, depending on individual hair type and maintenance.

One of the significant benefits of keratin treatments is their ability to reduce frizz and increase shine. By smoothing down the hair cuticle and sealing it, keratin treatments make the hair more manageable and less prone to frizz. This, in turn, gives the illusion of longer and healthier hair, as the ends are protected from splitting.

Keratin treatments are suitable for various hair types, including natural curls. For individuals with curly hair, keratin treatments can significantly reduce frizz and add shine. Curly hair tends to reflect less light, but after a keratin treatment, the increased shine becomes noticeable.

Keratin and Hair Growth

While keratin treatments may make hair seem to grow more quickly, their primary role is to strengthen the hair. Keratin helps add shine, reduce frizz, and temporarily bond the hair strands together, making them appear longer and stronger. However, the actual rate of hair growth remains the same. By reducing breakage and split ends, keratin treatments create the illusion of enhanced hair growth.

Keratin Treatments for Color-Treated Hair

In addition to their straightening effects, keratin treatments can also benefit individuals with color-treated hair. The treatment helps seal in the color, making it last longer and appear more vibrant. For optimal results, it is recommended to have the color refreshed right before a keratin treatment. This ensures that the color is locked in and protected, preventing premature fading.

Keratin Treatment Process

A keratin treatment typically takes several hours, depending on hair length and type. The process involves several steps to achieve the desired results. First, the hair is washed to remove any impurities. Then, the keratin treatment solution is applied to the wet hair, allowing it to penetrate the strands. After a designated period, the solution is blow-dried and sealed with a flat iron. This heat activation ensures that the treatment is locked in, providing long-lasting results.

Maintenance Keratin-Treated Hair

To maintain the effects of a keratin treatment, it is essential to follow specific guidelines. After the treatment, it is recommended to avoid getting the hair wet or using ponytails for at least three days. Water or bending of the hair can disrupt the newly straightened structure. Additionally, using sulfate-free shampoos and conditioners on hair wash days helps prolong the treatment’s efficacy. These products are gentler on the hair and do not strip away the keratin coating.

For individuals with natural curls, it is advised to refrain from wetting the hair for three days after a keratin treatment. Using hair products that are free of sodium chloride and wrapping the hair in a silk or satin scarf can help retain moisture and prevent dryness. While keratin treatments can last up to six months, it is important to note that they may alter the natural curl pattern permanently.

The Debate Surrounding Keratin Treatments

Despite their popularity, keratin treatments have faced scrutiny due to the ingredients used in traditional salon formulas. Many treatments contain formaldehyde derivatives, which are known to be harmful if exposed to high levels over time. Formaldehyde can cause various health issues, ranging from minor irritation to more severe conditions such as respiratory problems and cancer. Some hairstylists choose not to perform keratin treatments due to these potential risks.

To address these concerns, alternative formulations containing glyoxylic acid have been introduced. These formaldehyde-free treatments provide similar smoothing effects while minimizing health risks. It is crucial to discuss any concerns with your stylist and choose a treatment that aligns with your health and safety preferences.

At-Home Keratin Treatments

While professional keratin treatments yield the most effective and long-lasting results, there are options for at-home treatments. At-home treatments typically provide temporary results, as they coat the hair rather than penetrate the shaft. These treatments can be a cost-effective alternative but may not offer the same level of transformation as salon treatments. It is important to carefully read and follow the instructions provided and ensure proper ventilation during application.

The Future of Keratin in Hair Care

As the demand for safe and effective hair care products continues to rise, the beauty industry is exploring innovative ways to incorporate keratin. Researchers are constantly studying the properties and potential applications of keratin in hair care. From shampoos and conditioners to serums and supplements, keratin-infused products aim to enhance hair strength, reduce damage, and promote overall hair health.


Keratin, the mighty protein that forms the foundation of our hair, nails, and skin, has revolutionized the hair care industry. From professional salon treatments to at-home alternatives, the power of keratin in transforming frizzy and unruly hair into smooth and manageable locks is undeniable. However, it is crucial to consider the potential risks associated with certain formulations and choose treatments that prioritize both beauty and safety. With ongoing research and advancements, the future of keratin in hair care looks promising, offering endless possibilities for strong, healthy, and beautiful hair.
