When it comes to hair care, there are many “hot ticket” ingredients: shea butter, glycerin, ceramides, and so much more that would come up instantly. Less notable but just as important are amino acids for hair. They are fundamental in increasing moisture, strength and overall hair structure.

Amino acids are vital nutrients that contribute to good hair development. A deficiency in some of these compounds can lead to significant hair problems, including flat, dull tresses and hair loss.

Anyone looking for more well-built yet easy-to-manage locks should consider including amino acids in their hair care routine. These crucial building blocks will strengthen the scalp and hair for more sustainable hair growth and overall wellness.



Amino acids are fundamental building blocks that contribute to strong, well-hydrated hair. They are crucial for the formation of keratin, a key protein in hair structure.

Amino acids promote hair growth by improving blood circulation and nourishing hair follicles, making them essential for preventing hair loss and enhancing overall hair wellness.

Different amino acids have distinct benefits, such as cysteine for treating alopecia, methionine as an antioxidant, and lysine for inhibiting male pattern baldness.

Scandinavian Biolabs incorporates a blend of essential amino acids in their products to support healthy hair. Whether you're dealing with hair loss, thinning, or simply want better hair, amino acids play a vital role in maintaining strong and lustrous hair.

What are amino acids?

Amino acids are the molecular compounds that make up proteins, which are what we need to maintain life. In the human body, amino acids play various essential roles, but it's widely known that they're one of the main components of healthy hair.

The primary function of amino acids is to form keratin—a protein which helps make up your hair. Amino acids in the hair give it fullness, moisture, and shine.

Put simply: if you risk lacking amino acids, your hair will not grow at its fullest potential or retain its most appealing features. Instead, it might suffer from dryness, breakage, frizziness, and even hair loss.

How do amino acids benefit healthy hair?

The amino acids occur in your hair in the form of keratin. If you're looking for a way to make your hair look and feel better, consider adding amino acid-rich haircare to your routine. This one-of-a-kind ingredient can do much more than just keep your hair strong. Amino acids help promote growth by boosting blood flow and promoting healthy circulation to follicles, whether you are fighting off baldness or only want healthier locks.

Using hair products containing protein and amino acids together with other ingredients for nurturing, strengthening, and hydrating can help tremendously in both hair quality and retention.

Certain amino acids can add to the hair body, while others can strengthen it depending on which ones are used and the formulation. Hair care products containing amino acids have been shown to increase strength in damaged hair by improving overall thickness and durability.

Amino acids also bind with the cuticle to seal cracks and create a shinier appearance while giving it a silkier texture - no wonder some people call them silk vitamins!

If you want a healthier scalp, certain types of amino acids might help. It has been proved that these organic compounds can help manage Pityrosporum Capitis (dry dandruff) and Pityrosporum Steatoides (greasy dandruff), along with other assistance for scalp health!

Expected benefits of amino acids in your hair care routine:

  • Add hydration: Amino acids draw moisture into the hair, creating a barrier that prevents moisture loss and encourages healthy hair hydration.
  • Boost keratin formation: The protein that makes up 95% of our hair shaft is made of over 18 types of amino acids. Thus, utilizing amino acids boosts the production of keratin.
  • Provide protection: Amino acids fill damaged gaps in the outer hair cuticle, your hair’s protective layer.
  • Luxurious shine: Amino acids often include silk proteins that add an elegant shine to previously lacklustre hair
  • Stronger tresses: When amino acids fill in damaged gaps and boost keratin and moisture retention, the result is much stronger hair from root to end.
  • Volumise strands: Certain proteins in amino acids that are used in hair care add texture and volume to strands without adding weight and bulk.

How can I incorporate them into my hair care routine?

Not all amino acids are the same. There are many types of amino acids, and each one affects your hair differently. When it comes to preventing hair loss or aiding its growth, certain types of amino acids have been shown to be more effective than others. For instance, L-lysine (among other things) has been proven through extensive testing to significantly improve hair quality and lustre. Checking the ingredient list for these specific amino acids can help you find a product that will work best for your personal needs.

Below are some common types that have proven to assist hair wellness and support the treatment of hair loss.

  • Cysteine: has been proven to treat alopecia and other hair loss. Cysteine also enhances the texture and strength of existing hair.
  • Methionine is a potent antioxidant and key ingredient in battling hair disorders. Methionine increases blood supply to hair follicles and scalp, which is widely acclaimed among those with hair diseases like male pattern baldness, alopecia, and Hypotrichosis.
  • Lysine: aids in forming collagen, strengthening hair, and inhibiting 5 alpha-reductase from converting testosterone into DHT, the leading cause of male pattern baldness (androgenetic alopecia). Lysine absorbs calcium to encourage additional collagen production.

Amino acids in Scandinavian Biolabs hair care products

Each amino acid has its own unique function, but at Scandinavian Biolabs, we work to ensure a crucial complex that helps support and maintain healthy hair shafts. Our blend encompasses the amino acid complex, which is formulated with glycine, alanine, arginine, serine, valine, isoleucine, proline, threonine, histidine, and phenylalanine.

The benefits of these amino acids include:

  • Arginine is an amino with a strong affinity towards hair;
  • Histidine and phenylalanine can help improve your hair tensile strength;
  • Alanine in a hair conditioner has been proven by research to improve the hair surface hydrophobicity of bleach-damaged hair.

Also, our Hair Nutrient Tablets contain a blend of amino acids in combination with apple extract, horsetail extract, amino acids, B vitamins, vitamin C, and zinc to provide specific nutrients that support healthy skin, scalp, and hair.

The bottom line

In your hair, amino acids occur naturally in the form of keratin—the structural protein from which hair is made. Amino acids help promote growth by speeding up circulation in the scalp and encouraging healthy blood flow to follicles.

Whether you’re struggling with hair loss, alopecia, or just want a healthier head of hair; amino acids are the ticket. They are the building blocks of your body’s tissues, organs, and hair and are necessary for the strength and growth of every part of your body. Today, these proteins are also found in hair care products to benefit those experiencing hair loss, hair thinning, or hair that has become lacklustre, dull, and flat.

Using shampoos, conditioners, and treatments that contain certain amino acids helps to promote moisture retention and keep hair from breaking. Hair care products formulated with amino acids positively impact all hair types and textures to help give anyone who chooses to add them to their hair care routine smoother, silkier hair.
