The benefits of ceramides for hair.

Besides water, keratin, melanin pigments and mineral salts, the hair shaft also consists of oily substances that ensure the hair's barrier function (≃ 3% of the total hair composition). Within the cuticle, they notably help to seal the keratin scales to each other by forming an intercellular cement, thereby ensuring the protection of the cortex located at an intermediate level and providing a certain impermeability to the hair.

The lipids of this intercellular cement, produced at the bulb level, are composed of cholesterol sulfate, ceramides, sterols... Lipids are also present in the intercellular spaces of the cortex between the long fibrous cells and a monomolecular layer of a unique branched fatty acid, the 18-methyl eicosanoic acid, covers the surface of the hair. The texture and shine of the hair then directly depend on its condition. Indeed, when healthy, the scales are firmly linked, and the cuticle presents a smooth aspect allowing the reflection of light: the hair then appears shiny, flexible and silky.

Indeed, the cuticle is the first to suffer and endure all the daily aggressions (shampoos, repeated brushing, hairdryers, colouring/bleaching, UV, perming/relaxing...). It gradually loses its protective envelope and becomes fragile, thus becoming permeable: the structure of the hair is consequently weakened. Damaged, the scales separate, and the interior of the hair fibre (cortex) is therefore exposed to external aggressions.

On the other hand, when the scales of the cuticle are detached due to a lack of lipid cement, the water retained within the hair evaporates, which dries it out and makes it more fragile (loss of elasticity and plasticity). Although perceived as an aesthetic issue, the dry hair can eventually represent a hair health problem. They then appear fragile, porous, dull and tend to become brittle.

• Ceramides nourish the hair.

  If your hair is dehydrated and lacks lustre, treatments formulated with ceramide are a solution. They prevent water from evaporating and nourish your hair. Moisturising, they help you regain smooth, split-end free hair.

• Ceramides to maintain the radiance and shine of hair.

  Applying a ceramide treatment to the scalp helps to keep it radiant. It allows your hair to maintain its shine.

• Ceramides, a protective element of the hair fibre.

  Applying a treatment containing this active ingredient helps to protect the hair fibre from external aggressions. Ceramides assist you in combating and preventing breakages. Ceramides are lipids that can be found on the scales of the hair. Their function is to strengthen the hair fibre. They fortify the roots and enhance the cohesion of the hair cells. They act like a protective cement.

• Ceramides to improve hair texture.

  If you desire smooth, soft, and supple hair, opt for treatments containing ceramide. They assist you in achieving smooth, frizz-free hair. They also allow you to tame unruly hair and thus create a hairstyle according to your wishes.
