If you are tired of fighting frizz in your hair, if you notice that your hair is dry, dull or with split ends, then keratin is the solution you are looking for. In this article, we will explore everything related to keratin, what it is, how it works and even the benefits it offers for healthier hair.

What is Keratin?

Keratin is a fibrous protein that is found naturally in our body, especially in hair, skin and nails. It is responsible for providing resistance and structure to these elements. Focusing on hair, it is its main component and is essential to keep it strong, healthy and resistant to damage. Simply put: keratin acts as a protective shield, strengthening and protecting the hair shaft from within.

How does this protein work in hair?

When hair is damaged due to factors such as sun exposure or the use of heat tools, the amount of keratin decreases, leaving hair weaker and more prone to breakage . It is at that moment when many people decide to apply a keratin treatment .

When applied to the hair, keratin penetrates the hair shaft, replenishes lost protein and repairs damage caused by the aforementioned external factors. And what is more interesting: it forms a protective layer that protects the hair from further damage while restoring its natural shine, softness and strength .

It is also important to point out that keratin is a protein resistant to water and heat, which makes it an ideal ingredient to protect hair from damage caused by thermal tools, such as straighteners and dryers .

Another cause of keratin loss is the passage of time. As we age, the activity of the cells responsible for producing keratin in the hair follicle can decrease, which can lead to less production of this protein. This can result in thinner , less dense hair with less vigor.

Benefits of keratin for hair

Keratin offers a wide range of benefits for the health and appearance of hair. These are some of the main ones:

• Restoration and repair . Keratin penetrates the damaged hair fiber, filling in gaps and repairing damage. This helps restore hair’s natural softness and shine.
• Elimination of frizz . One of the most common problems if we talk about hair care is frizz. Keratin acts as a protective barrier that prevents the absorption of moisture from the environment, keeping hair soft and frizz-free 
• Reduction of styling time . With hair treated with this protein, styling time is significantly reduced. Hair becomes more manageable and easier to comb, simplifying your daily routine.
• Strengthening . As the main component of hair, the addition of keratin strengthens the hair, making it more resistant to breakage, preventing hair loss .

Conclusion

As you have read, keratin is a powerful ally to obtain healthy, soft and radiant hair . With its numerous benefits and treatment options through different products, it is possible to transform the appearance and texture of your hair effectively.
