I. Reminder on what Collagen is?

Collagen is a structural protein that forms connective tissue throughout the body.

There are several types of collagen, types I, II, and III being the most common, and the benefits of collagen are numerous. 


The benefits of marine collagen for hair are found in type I (present in the skin, tendons, and bones) and type III (present in the skin and blood vessels), which are particularly important.


II. Importance and role of collagen for hair

Collagen is a fundamental structural protein that forms connective tissue throughout the human body.


It constitutes about 30% of the total proteins in the body and plays a crucial role in maintaining the structure and integrity of various tissues, including the skin, bones, tendons, ligaments, and hair fibers.


There are at least 28 types of collagen identified, but types I, II, and III are the most common and the most studied.


For the hair, type I and III collagen are particularly important.


Type I collagen is mainly found in the skin, tendons, and bones. It contributes to the strength and resilience of hair fibers by providing the amino acids necessary for the production of keratin, the main protein constituting hair.

Type III collagen, for its part, is mainly found in the skin and blood vessels. It helps maintain the elasticity and the structure of the scalp, promoting a healthy environment for hair growth.


Collagen also acts as an antioxidant, protecting hair follicles from damage caused by free radicals.

These free radicals are unstable molecules generated by various factors, such as pollution, stress, and UV rays, which can damage hair cells and weaken the hair structure.


By neutralizing these free radicals, collagen helps prevent damage and maintain hair health.


In summary, collagen is not just a structural protein, but a key element for hair health.


It provides the basic elements necessary for keratin production, maintains the elasticity and hydration of the scalp, and protects hair follicles against environmental damage.


Its multifunctional role makes it an essential ingredient for those looking to improve the quality and strength of their hair fibers.

1. The benefits of collagen for hair

Hair Strengthening

Collagen provides essential amino acids, such as proline, necessary for the production of keratin, the protein that mainly makes up hair. An increase in keratin production thanks to collagen can lead to stronger hair that is more resistant to damage.

Prevention of Hair Damage

The antioxidant properties of collagen help fight free radicals that can damage hair follicles. By protecting these follicles, collagen helps prevent brittle hair and split ends.

Hydration and Elasticity

Collagen helps maintain hydration of the scalp and hair. A well-hydrated scalp promotes more elastic hair that is less prone to breakage.

Hair Growth Stimulation

By improving blood circulation in the scalp, collagen can stimulate hair growth. Better circulation means that hair follicles receive more nutrients and oxygen, essential for hair growth.

Hair Loss Reduction

By strengthening hair structures and improving the overall health of the scalp, collagen can help reduce hair loss due to breakage or follicle weakness.

2. How to integrate it into your hair care routine

  • Collagen dietary supplements: Collagen supplements, available in powder, tablet, or capsule form, are an effective way to increase your collagen intake. They can be added to your daily regimen for internal benefits that are reflected in your hair, as well as your body in general.


  • Foods rich in collagen: Incorporating foods rich in collagen such as bone broth, fish, poultry, and leafy green vegetables into your diet can also help increase collagen production in the body, and your hair will thank you.


  • Hair products based on collagen: many shampoos, conditioners, and hair masks now contain collagen. These products can provide additional hydration and protection directly to the hair and scalp. You can find ready-made hair products or buy collagen concentrates to add to your hair preparations.


  • Vegetable oils: use vegetable oils such as argan oil, broccoli oil, or rocket oil, which contain beneficial properties for hair, in combination with collagen to further enhance the benefits and stimulate hair growth while protecting it.


3. Biotin and collagen: a winning combination

Biotin, also known as vitamin B7, is an essential nutrient for hair health. When combined with collagen, it can offer synergistic benefits. Biotin helps strengthen hair and prevent hair loss, while collagen improves elasticity and hydration. Together, they form a powerful combination for stronger and healthier hair.

4. Its impact on hair and nails

Collagen is not limited to improving hair health; it also has a positive impact on nails. By strengthening the nail structure, collagen can help prevent breakage and promote faster growth. Nails become stronger and less prone to cracking.

5. Use in powder form

Collagen powder is a popular option for those looking to incorporate this protein into their daily routine. Easy to add to smoothies, drinks, or even cooking recipes, collagen powder offers flexibility of use while providing the same benefits for hair and skin.

6. The importance of natural collagen

Natural collagen, extracted from sources such as fish or beef, is often preferred for its bioavailability and effectiveness. Natural collagen products are better absorbed by the body, which helps maximize the benefits for hair and skin. Choosing natural collagen sources also ensures better compatibility with the body.

7. What are the health and beauty benefits of hair?

The benefits of collagen for the health and beauty of hair are numerous. It helps to strengthen the hair structure, prevent damage, maintain hydration, and stimulate growth. By protecting hair follicles and improving blood circulation, collagen contributes to healthier and shinier hair.

8. Is it good to take it every day?

Taking collagen daily can be beneficial for hair health. Regular consumption helps maintain a constant level of this essential protein in the body, thus promoting lasting results. However, it is always recommended to consult a healthcare professional before starting any new supplement.

9. Which type is best suited for hair?

Type I and III collagen is particularly beneficial for hair. Type I, found in the skin, tendons, and bones, helps strengthen hair and improve its resilience. Type III, found in the skin and blood vessels, maintains the elasticity and structure of the scalp, promoting a healthy environment for hair growth.

10. What is the best collagen for hair?

The best collagen for hair depends on individual needs and preferences. Marine collagen, extracted from fish, is often considered one of the best sources due to its high bioavailability. However, bovine collagen is also a popular option for its similar benefits. Choosing a high-quality product from natural sources ensures the best results.
