Amino acids are the building blocks of protein in the body, yet protein is still required outside of our bodies. For example, the protein keratin makes up around 88 percent of our hair. We can’t make more of it without the right amino acid balance for hair development.

It is better to work from the outside instead of attempting to make your hair glossy and thick with oils, conditioners, and other items. These items clog up your scalp. Where to get this amino acid in your diet is also described here.

For muscle growth and strength there is a requirement of protein. Therefore it stands to reason that it is also required for hair growth.
Keratin, a protein, is the main component of hair. Hair keratin is made up of 16 amino acids that are ‘keratinized’ (or turned into keratin) in the scalp before hair emerges from the surface.

There should be the deliverance of amino acids to the scalp for the keratin to develop and hair to grow. So you would think that eating a lot of amino acids could help you develop more hair, thicken your hair, and even stop hair loss. Although it’s not quite that straightforward, ingesting large amounts of certain important amino acids can significantly and quickly enhance the health of your hair.

How Does Amino Acid Work For Hair Growth?

Amino acids have a variety of functions in the human body, but one of the most significant is hair development. For the formation of keratin, there is a requirement of amino acids. It is the fundamental building block of hair strands, as previously stated.

Sixteen different amino acids make keratin. Furthermore, amino acids assist in the production of red blood cells in the body. This red blood cell synthesis contributes to the transport of oxygen and nutrients to hair follicles on the scalp. It improves hair health and promotes healthy hair growth. It is critical to consume all of the needed amino acids each day to have healthy hair and a healthy hair development process.

If you could just add amino acids to your diet, you could stimulate hair growth effectively. Keratin, a specific type of protein, makes up the majority of hair. Amino acids make the majority of keratins in hair. There are a variety of meals to choose from. Focusing on those that contain amino acids appears to be gaining favor.

Amino acids are the building components of hair. Certain kinds of amino acids combine to produce keratin. Aside from that, amino acids have additional functions. They are the ones who make red blood cells. The more RBCs you have, the better. RBCs are important not just for hair development, but also for the body’s overall health.

The red blood cells give vital nutrients to the hair follicles, which encourage hair growth. While four of these amino acids are essential for hair development, there are 20 more that are essential for overall body health.

Some Top Amino Acids For Healthy Hair.


In our bodies, L-Tyrosine acts as a natural affiliate. It communicates with our thyroid and helps the thyroid, pituitary, and adrenal glands regulate important hormones. It’s in charge of producing melanin, which gives us our hair color.

It’s also one of the amino acids that aid in the regrowth of good hair. Lack of this hormone causes stress-related hair loss. Telogen effluvium, alopecia areata, and trichotillomania are all examples of stress-induced hair loss. Enhance your diet of L-tyrosine-containing foods such beef, pig, fish, poultry, tofu, milk, cheese, beans, seeds, nuts, and whole grains as a natural approach to increase this amino acid.

It is categorized as an essential amino acid, which means it cannot be synthesized by the body and must be obtained from the diet or herbal supplements. This vital amino acid also contains sulfur, which helps to prevent hair problems, as well as potent antioxidant properties.

Methionine, a lipotropic, breaks down fat in the bloodstream and keeps it from accumulating, making it beneficial for cardiovascular health and ensuring adequate blood flow to our scalps and hair follicles, both of which are essential for healthy hair development. Methionine is also required for the production of collagen, which is necessary for hair shaft strength.

Brazil nuts are a good source of protein. Fish, eggs, seeds of sesame, grains of cereal are some of the diets containing methionine.


The link between arginine and nitrogen oxide is significant because arginine aids in the production of nitrogen oxide. The opening of potassium channels in scalp cells is aided by this. There are a variety of additional events that occur within the body when these potassium channels activate.

The dilation of blood arteries is triggered by the activation of potassium channels within cells. This increases circulation by allowing blood to flow more freely through the blood vessels. This increase in blood flow and circulation ensures that hair follicles receive adequate blood supply. As a result, hair growth is stimulated.

Because arginine is a precursor to nitric oxide, it plays an important role in healthy hair development. Nitric oxide is required to increase blood flow to our scalps and to aid our immune system’s defenses against autoimmune illnesses, including those that might cause baldness.

Sesame seeds are a good source of protein. Coconut, hazelnuts cashew, sunflower seeds, fish, wheat grain are good sources of arginine.

Cysteine is also known as L-Cysteine and contributes to the protein production process that helps to produce hair strands through keratin, much like the other amino acids described above. Because of its propensity to generate disulfide connections in the body, cysteine is a unique amino acid.

This capacity to form disulfide bonds is significant when considering Cysteine’s role in hair development since disulfide bonds are what hold the keratin strands together. This mechanism is responsible for the fibrous qualities of human hair strands, which allow them to retain moisture and feed hair follicles. This helps to keep your scalp from becoming dry and irritated.

Furthermore, cysteine is important for maintaining the thickness and texture of the hair. To comprehend the significance of cysteine in hair growth, it is necessary to first comprehend how each hair is produced. A cuticle, cortex, and medulla are all present on each hair strand.

The cuticle is the hair follicle’s outermost coat, which protects the medulla and cortex. The cortex then surrounds the medulla, which is the hair shaft’s core. The medulla is the part of the hair that regulates the thickness of the hair. The cortex is the most visible layer, accounting for eighty to ninety percent of each hair strand.

The keratin molecules makes the cortex that has bonded together. It gives the hair strands their strength. Cysteine is found in around 75% of the fibrous filaments of bonded keratin molecules, making it an important element of the hair development process. Brussels sprouts, broccoli, chicken, and wheat germ are all good sources of Cysteine.



Glycine is vital for hair because it assists with collagen formation, as well as digestive health and the health of our central nervous systems, which means it can help prevent hair loss caused by nerve problems. Meat, fish, spinach, dairy products, soybeans, bananas, cabbage, and beans are all good sources of protein.

Collagen is the most prevalent protein in your body, and glycine is one of its key building elements. Supplementing your diet with the building blocks: vitamin C and glycine can provide strength for your muscles, skin, hair cartilage, blood, bones, and ligaments.

While ingesting collagen isn’t the best way to boost collagen levels in your hair, supplementing your diet with the building blocks: vitamin C and glycine can provide strength for your muscles, skin, hair cartilage, blood, bones, and ligaments.


Dietary amino acids and even external amino acid conditioning treatments are safe, natural, and caring ways to care for your hair’s keratin for increased hair development and follicle health. You can enrich and strengthen your hair without hurting it with a few dietary modifications, amino acid supplements, or amino acid treatments.
