Discover why amino acids are the foundation of healthy hair. Learn how they restore structure, enhance shine, and renew hair fibers from within.
Amino acids in hair care – the building blocks of healthy hair
Healthy, strong, and shiny hair starts with the foundation – amino acids . These microscopic molecules form the building blocks of keratin , the main component of our hair. In modern hair science, amino acids are considered the key to repair, hydration, and long-lasting protection. But what exactly do they do, and why are they essential in professional hair care?
What are amino acids anyway?
Amino acids are organic compounds that combine to form proteins —including keratin, collagen, and elastin. Our hair consists of over 90% keratin, made up of 18 different amino acids. The most important are:
✔ Cysteine – strengthens disulfide bonds and increases elasticity.
✔ Arginine – stimulates microcirculation and hair growth.
✔ Serine & Threonine – help retain moisture and smoothness.
✔ Glycine & Alanine – improve hair flexibility.
Together they provide strength, shine and resilience to each hair strand.
How Amino Acids Work in Hair Care Products
When hair is damaged by heat, chemicals, or the sun, the keratin bonds break. Amino acids can rebuild this structure from within .
✔ They penetrate into the cortex (the inner layer of the hair).
✔ They fill in open spaces in the hair structure.
✔ They restore the natural moisture balance.
✔ They close the hair cuticles, making the hair shinier and stronger.
That's why amino acid-based treatments – such as Nanoplastia or Amino Hair Therapy – are so effective for deep restoration.
The Benefits of Amino Acids in Hair Care
✔ Deep repair – replenishes damaged parts of the hair fiber.
✔ Hydration – attracts and retains moisture.
✔ Protection – strengthens the hair’s natural barrier.
✔ Elasticity – prevents breakage and split ends.
✔ Color retention – helps retain pigments for longer.
They work not only superficially, but at the molecular level – exactly where damage occurs.
Amino acids in professional treatments
In salon treatments, amino acids are often combined with other active ingredients such as keratin, oils and plant extracts.
✔ In Nanoplastia they provide steepness and reconstruction without damage.
✔ In Hair Botox they strengthen the fiber while smoothing.
✔ In Bioplastia they provide a restorative and moisturizing effect at the same time.
These treatments transform hair from within – without harsh chemicals.
Conclusion: Amino acids are the basis of healthy hair
Without amino acids, hair can't repair, grow, or shine. They form the DNA of hair health. Whether you choose a salon treatment or home care, products with amino acids are the essential fuel for strong, supple, and vital hair.
