1: Understanding Keratin

1.1 What is keratin?

Keratin is a fibrous protein found naturally in the human body , playing an essential role in the structure and health of hair and skin. It is mainly made up of amino acids, such as cysteine, methionine and tyrosine, which combine to form strong, strong protein chains.

Structure and composition of keratin:

Keratin looks like long twisted threads in the shape of spirals. This special shape gives it its strength and its ability to hold up well. It's a bit like the springs that keep our mattresses in good condition. These keratin threads serve as strong foundations and protective barriers wherever they are in our body, such as our hair, skin and skin appendages.

Role of keratin in the human body:

Keratin performs various essential functions in the human body. In the hair, it constitutes the majority of the hair fiber, ensuring its resistance, flexibility and shine, in particular by sealing the scales of the hair which thus reflects the light better. On the skin, this protein helps maintain its structural integrity by forming a protective barrier against external aggressions, while promoting cell regeneration. Finally, in the nails, this molecular spring provides strength and resistance, helping to prevent breakage and cracking.

Origin and manufacture of keratin used in cosmetics and nutricosmetics:

The keratin used in cosmetic and nutricosmetic treatments can have different origins. It can be of animal origin, generally coming from sheep's wool or bird feathers,

The animal keratin extraction process begins by collecting animal by-products, such as feathers, hair or claws, from slaughterhouses or other sources. These raw materials are then processed to clean, disinfect and break them into smaller pieces to facilitate the extraction process. Next, the raw materials undergo hydrolysis, a chemical or enzymatic process aimed at breaking protein bonds and separating the keratin from other components. Once the keratin is extracted, it is purified to remove impurities and residue, resulting in a solution containing keratin peptides. Finally, these keratin peptides are processed into final products such as powders, gels or liquids, suitable for use in various industries such as cosmetics or pharmaceuticals. This process makes it possible to valorize animal by-products by extracting and using keratin efficiently.


But it can also be of plant origin, extracted from sources such as wheat, soy or corn. The extraction process of plant keratin differs from that of animal keratin due to the origin of the raw materials. Unlike animal keratin, which is extracted from animal by-products such as feathers, hair or claws, plant keratin comes from plant sources such as wheat, sea algae or quinoa seeds. The plant keratin extraction process begins with the selection of protein-rich plant raw materials, which are then processed to release the proteins and beneficial compounds. Then, plant proteins are extracted from the raw materials using specific techniques such as solvent extraction or water extraction. The extracted proteins are then purified to remove impurities and contaminants, resulting in a high-quality final product. Finally, plant keratin proteins are processed into various finished products suitable for use in various industries such as cosmetics, nutrition and health. In our Absolu+ Hair , we use a unique and patented plant-based keratin, grown in France in the Chambord region and extracted using an environmentally friendly process.

This process highlights the importance of choosing the right raw material sources and extraction methods to achieve high-quality keratin care, whether animal or plant-based.

1.2 The different types of keratin

Keratin exists in different forms and can be classified into several categories depending on its origin and its properties. Here is an overview of the main existing types:

Alpha and beta keratin: what are the differences?

Keratin can be classified into two main categories: alpha and beta. The alpha form is the most common in the human body, especially in the appendages and skin. It is responsible for the strength and structure of these tissues. The beta form, on the other hand, is less common and is mainly found in the hair, feathers and claws of animals.

Animal keratin vs. plant keratin: advantages and disadvantages

Keratin can be extracted from animal or plant sources. When animal, it is usually derived from sheep's wool, bird feathers, or animal hooves. It is appreciated for its similarity to that which is naturally present in the human body, but can pose ethical and environmental problems. On the other hand, when it is plant-based, it is obtained from sources such as wheat, soy or corn, offering a more sustainable and environmentally friendly alternative, although its similarity to the human form may vary.

Importance of the quality and purity of keratin in care

Whatever its origin, the quality and purity of keratin used in hair, nail and skin care are crucial to guarantee their effectiveness and safety. High-quality protein, obtained from controlled sources and carefully purified, is essential to providing the nutrients needed for healthy skin and hair. It is therefore important to choose products containing a quality form, formulated with safe and beneficial ingredients for health.

1.3 The importance of keratin for aesthetics

Keratin plays a crucial role in preserving and enhancing the natural appearance, particularly of hair, skin and nails. Its importance lies in several key aspects:

Health impact of keratin on hair, skin and nails:

Keratin is an essential part of the structure of hair, skin and nails.

Additionally, using keratin on hair and skin helps maintain its hydration, ensuring it looks clear and vibrant.

Relationships between keratin deficiencies and aesthetic problems:

Keratin deficiency can lead to various aesthetic problems, such as repairing damaged, brittle and dull hair, hydrating dry and dehydrated skin , as well as strengthening weak and crack-prone nails. These signs often indicate a weakening of tissue structure, caused by a lack of this molecule and other essential nutrients. Therefore, it is important to maintain adequate levels of this key molecule for healthy skin and hair.
