KERATIN • BIOTIN - 30 CAPSULES

Keratin is an essential structural protein that makes up nearly 95% of the hair fiber, as well as the structure of the skin and nails.

With age, stress, deficiencies, hair coloring, straightening, pollution or blow-drying, its quality decreases: thinner, more brittle, dull hair; soft nails; drier skin.

A supplement based on Cynatine® HNS, a patented and scientifically studied bioavailable keratin, helps to:

• strengthen the hair fiber,
  
• reduce reactive hair loss and breakage,
  
• stimulate growth and density,
  
• improve resistance and shine,
  
• strengthen nails,
  
• improve skin hydration and elasticity.
  

It is today one of the most effective active ingredients to improve the overall appearance of hair, nails and skin.

Cynatine® HNS is a patented bioavailable keratin, obtained through an exclusive process that preserves the native structure of keratin (sulfur-containing amino acids such as cysteine).

This process makes it assimilable by the body, unlike most hydrolyzed keratins which are not effectively absorbed.

Clinical studies show that Cynatine® HNS:

• reduces hair loss,
  
• increases density and shine,
  
• improves resistance and reduces breakage,
  
• strengthens soft and brittle nails,
  
• improves skin hydration and elasticity.
  

It is today the most scientifically documented form of keratin.

Our formula combines three key active ingredients — patented Cynatine® HNS keratin, highly bioavailable biotin and zinc — which act in a complementary way on hair growth, hair fiber strength, skin quality and nail solidity.

Keratin, the main component of the hair fiber and nail structure, is essential to strength, shine and density. With age, external aggressions, stress, pollution, hair coloring or heat, its natural quality decreases.

Cynatine® HNS is a highly assimilable form, scientifically studied to improve hair resistance, reduce breakage, decrease reactive hair loss, increase density and restore shine. Clinical studies also show a positive effect on skin hydration, elasticity, suppleness and wrinkle reduction.

Biotin, essential for keratin synthesis, supports cellular metabolism, improves scalp vitality, stimulates growth and reduces hair loss. It also strengthens soft, fragile or split nails by improving their structure and resistance.

Zinc, in turn, acts on several levels: hair growth, reduction of oxidative stress, skin balance, scalp quality, sebum regulation and immune system support. It plays a major role in skin health (blemishes, inflammation, repair) and in preventing deficiency-related hair loss.

Combined, these three actives create a complete nutricosmetic synergy which simultaneously acts on:

• hair loss (seasonal, stress, deficiencies)
  
• breakage and fragility of lengths
  
• density, volume and shine
  
• faster and stronger growth
  
• brittle or split nails
  
• skin quality: hydration, elasticity, radiance
  
• the fight against skin aging

The first results are often visible from 30 days, then intensify after 2 to 3 months of use. Prolonged intake helps to maintain the benefits and to lastingly improve the appearance of hair, skin and nails.

Biotin, also called vitamin B8 or vitamin H, is one of the most essential nutrients for the beauty of hair, skin and nails. It plays a central role in:

• the synthesis of keratin, the main protein that makes up the hair fiber and nail structure;
  
• the metabolism of fatty acids, essential to the proper functioning of the scalp and to hair growth;
  
• the overall quality of keratin tissues (hair, nails, skin).
  

An insufficient biotin level can lead to:

thin, brittle hair, lack of volume, increased hair loss, soft or split nails, dull or irritated skin.

Biotin supplementation therefore helps to restore optimal functioning.

Its scientifically recognized benefits:

1. Naturally stimulates hair growth

Biotin promotes the activity of hair follicles, supports hair growth and improves regrowth speed. Hair grows faster, looks stronger and gains vitality.

2. Reduces hair loss and strengthens resistance

By improving keratin production and cellular metabolism, biotin helps to reduce reactive hair loss (stress, fatigue, season) and makes hair more resistant to breakage.

3. Improves thickness, quality and shine

A better-nourished fiber is a denser fiber: biotin helps to thicken the hair diameter, increase its suppleness and restore its shine and radiance.

4. Strengthens soft, brittle or ridged nails

By stimulating keratinization, it improves nail solidity, reduces breakage and limits splitting. Nails become more compact, smoother and more resistant on a daily basis.

Biotin + Cynatine® HNS + zinc: a clearly more effective synergy

Taken alone, biotin is already beneficial.

But combined with:

• Cynatine® HNS (patented bioavailable keratin): deep fiber reconstruction, resistance, shine,
  
• Zinc: anti-hair loss, antioxidant, sebum regulation, scalp health,
  

its effectiveness is clearly amplified.

This combination strengthens the hair fiber from within, optimizes growth, reduces breakage, improves density, and acts simultaneously on nails and skin.

Yes, in several cases:

• seasonal hair loss (autumn / spring),
  
• reactive hair loss (stress, fatigue),
  
• deficiency-related hair loss,
  
• fragility after coloring or aggressive treatments.
  

Cynatine® HNS + biotin + zinc act simultaneously on:

• hair strength (structure),
  
• the bulb (anchoring),
  
• growth,
  
• resistance,
  
• shine.
  

For severe hormonal hair loss (postpartum, hormonal imbalance), efficacy will depend on the individual context, but the improvement in resistance and regrowth speed is generally there.

Yes — and it is even strongly recommended.

Indeed, this type of treatment:

• weakens the fiber,
  
• increases porosity,
  
• damages natural keratin.
  

Cynatine® HNS helps to:

• repair the fiber,
  
• strengthen the structure,
  
• reduce breakage,
  
• protect from future aggressions.
  

It is the ideal cure for sensitized hair.

Yes, and clinical studies confirm it:

Cynatine® HNS:

• significantly increases resistance,
  
• reduces breakage,
  
• improves growth,
  
• strengthens the keratin structure.
  

It is one of the most effective ingredients for soft, fragile or thin nails.

Yes.

Thanks to its overall action:

• Cynatine® HNS increases hydration,
  
• improves elasticity,
  
• reduces the appearance of fine lines,
  
• strengthens the barrier function,
  
• improves overall radiance.
  

It is a true nutricosmetic synergy, acting from within for more supple and luminous skin.

Because:

• it is bioavailable (actually absorbed),
  
• it has published clinical studies,
  
• its efficacy is measured and reproducible,
  
• it contains the sulfur-containing amino acids necessary for the keratin structure.
  

Most keratins on the market have no clinical evidence.

Cynatine® HNS is one of the rare premium forms scientifically validated.
