I. Reminder on what is Collagen?

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

There are several types of collagen, with 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 ( found in skin, tendons and bones ) and type III ( found in skin and blood vessels ) 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 approximately 30% of the body's total proteins and plays a crucial role in maintaining the structure and integrity of various tissues, including skin, bones, tendons, ligaments and hair fibers.


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


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


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

Type III collagen, on the other hand, is mainly found in the skin and blood vessels. It helps maintain elasticity and 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 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 building blocks necessary for keratin production, maintains scalp elasticity and hydration, and protects hair follicles from environmental damage.


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