Want to find dense and vibrant hair? Whether in shampoo, professional care or food supplements for hair , discover the benefits of keratin, a natural protein essential to hair health.
What is keratin?
Keratin is a natural, insoluble and fibrous protein, present in large quantities in the integuments, that is to say the nails, hair, hair, both in humans and animals. It is also responsible for the strength, flexibility and shine of the hair.
Chemically, keratin is made up of amino acids, including cysteine, methionine, lysine and arginine, which give it its strength and strength.
However, over time, natural keratin production decreases, which can weaken hair and make it more susceptible to breakage. This is why it is important to maintain a good level of keratin to maintain healthy hair.
The benefits of keratin for hair
Keratin is a valuable ally for hair, and here's why:
Strengthens and sheaths the hair fiber
By forming a protective layer around the hair, keratin protects it from external aggressions such as the heat of styling appliances, the sun's UV rays or pollution.
Repairs damaged and brittle hair
Keratin penetrates deep into the hair fiber and helps repair damaged and brittle hair. It is also responsible for the elasticity of the hair, which prevents it from breaking when brushing, for example. Hair is visibly healthier and more resilient.
Smoothes and reduces frizz
Keratin also has smoothing properties that help to permanently straighten hair, reduce frizz, and improve hair shine and suppleness.
Hydrates and adds shine
By sealing moisture inside the hair, keratin helps lock in moisture and prevent dryness. Well-hydrated hair is not only softer and more manageable, but also reflects light better, making it look shinier and healthier.
Accelerates growth
Keratin is a natural protein that strengthens hair and stimulates its growth. It acts by filling gaps in the hair fiber, protecting it from external aggressions and stimulating blood circulation in the scalp.
Using keratin-based products can improve hair strength, and thus promote optimal growth.
How to use keratin?
Keratin is a versatile ingredient that can be used in different ways to benefit from its benefits.
Keratin-based hair care
Hair masks, shampoos and conditioners enriched with keratin aim to strengthen the hair and restore its health by filling in gaps in the fiber.
However, this care has its limits. Indeed, since they act on the surface of the hair, their impact remains superficial. Good practice would be to use them occasionally after attacks such as bleaching, straightening or exposure to the sun.
