KERATINE FORTE SERUM PACK

A keratin hair serum is designed to deeply repair damaged hair by directly strengthening the hair fiber. Keratin, the main protein in hair, acts as a structural element capable of filling weakened areas and restoring internal cohesion. This action improves hair's resistance and elasticity, thereby limiting breakage and progressive degradation of the fiber.

Beyond repair, a keratin serum also helps to smooth and tame hair. By coating the fiber, it visibly reduces frizz and improves the flexibility of the lengths, making daily styling easier. Finally, it acts as a protective shield against external aggressions such as heat, UV rays, or pollution, which are responsible for the progressive weakening of hair. This global approach corresponds to the Biocyte vision: a targeted and synergistic action to sustainably restore hair quality.

Keratin is an essential protein that makes up to 95% of the hair fiber. It ensures the hair's strength, cohesion, and impermeability. When supplied via a keratin serum, it strengthens the existing structure by filling gaps in the fiber and consolidating its internal architecture.

The hair fiber is made up of several layers: the cuticle, which protects and provides shine; the cortex, which provides structure and elasticity; and the more central medullary part. When hair is damaged, particularly by chemical or mechanical aggressions, internal bonds such as disulfide bridges weaken. As a result, the fiber becomes porous, brittle, and dull. Keratin helps gradually restore this cohesion, thereby improving the hair's appearance and hold.

A keratin hair serum like Biocyte’s Keratine Forte Serum provides an immediate coating effect that instantly improves hair texture. The hair fiber becomes smoother, more even, and visibly stronger. This results in softer, shinier hair that is easier to style.

Its formula is based on a synergy of innovative active ingredients: keratin to strengthen the hair fiber, PQQ to stimulate cellular activity, ANAGAIN™ to support hair growth, and LEGACTIF™ to enhance scalp microcirculation. This combination helps deliver measurable results, including improved hair density and overall quality over time. The serum’s lightweight texture also allows for easy application without a greasy or heavy feel, making it suitable for all hair types, even the finest.

A keratin hair serum is suitable for all damaged hair, whether it is dry, fine, thick, or sensitized. It is also suitable for straight, wavy, curly, coily, or kinky hair, as its action is based on the internal structure of the fiber and not on the hair's nature. Its objective is to strengthen and protect, regardless of hair texture.

It is particularly beneficial for color-treated or bleached hair, which is often weakened by chemical treatments. Similarly, gray or white hair, which is naturally more porous and drier, benefits from keratin to improve its strength and shine. This versatility makes it a versatile treatment, suitable for a wide variety of hair profiles.

Using a keratin hair serum involves regular application on dry hair to optimize its effects. Daily use is generally recommended to maintain a constant supply of active ingredients and support long-term hair fiber quality. For optimal application, a few drops are sufficient.

A keratin serum is part of a complete hair care routine to maximize its benefits. The protocol begins with a suitable shampoo to cleanse the scalp and prepare the hair fiber to receive the treatments. It is then recommended to apply a conditioner or mask to moisturize and smooth the cuticle.

The keratin serum then acts as a targeted treatment, working deeply to strengthen the hair fiber. If necessary, a styling product can complete the routine to structure the hairstyle and extend the serum's effects. This multi-step approach optimizes the penetration of active ingredients and maintains visible results over time.

A keratin hair serum primarily acts on the lengths and hair fiber. It aims to repair, strengthen, and protect the hair by improving its internal structure and external appearance. Its action is therefore focused on the quality and resistance of the fiber. Conversely, a serum containing peptides or specific plant extracts acts more at the scalp level. It targets mechanisms related to the hair life cycle, particularly growth and shedding.

The Biocyte Keratin Forte Serum stands out with a hybrid approach, combining keratin with active ingredients like ANAGAIN™ and LEGACTIF™, which act on both the fiber and the scalp environment. This dual action allows for combining hair strengthening and growth support, in a logic of overall and measured performance.

A well-formulated hair serum does not weigh down fine hair. Its light texture allows for rapid penetration into the hair shaft without leaving a greasy film on the surface. Keratine Forte Serum has been specifically designed to provide a strengthening effect without compromising the hair's natural volume. On the contrary, by improving the internal structure of the hair fiber, it can help give a feeling of thickness and density, without a stiff or flat effect.

It is not mandatory to wash your hair before applying a serum. It can be used on clean hair or between washes, depending on your needs. However, applying it after shampooing can improve the penetration of active ingredients, as the hair fiber is more receptive. In the case of Keratine Forte Serum, it is recommended to apply it preferably after washing on dry hair to optimize its effectiveness.

Yes, a keratin hair serum can be used daily. This regularity ensures a continuous supply of active ingredients and achieves visible results in hair quality. In the case of Keratine Forte Serum, regular use is part of a structured protocol with an initial attack phase followed by a maintenance phase, in order to optimize results in terms of hair strength, density, and vitality.
