Obviously healthy hair requires a lot of keratin and, to a lesser extent, collagen. In order for the body to produce these structural proteins, it must have sufficient access to certain amino acids.

There are four major amino acids needed for keratin production: cysteine, lysine, arginine and methionine. Collagen production relies on access to the amino acids lysine, methionine, glycine and proline.

Of these amino acids, methionine and lysine are classified as essential, meaning they must come from our diet. The other important amino acids for healthy hair growth can be synthesized by the body, although they may be at low concentrations if the diet is poor.

By increasing the availability of key amino acids involved in the production of keratin and collagen, you can fight hair loss and stimulate new hair growth.

In addition to helping keratin production, arginine is a very important amino acid. Among any critical health benefits, it has improved immune function and helps minimize disease-related hair loss. Studies have shown that this amino acid can help protect hair from the harmful effects of hair dye and bleaching.

Arginine is also essential for the production of nitric oxide (NO). This is essential for improving blood flow and providing nutrition for hair follicles. This allows for healthy hair growth.

Although not essential amino acid, there are cases where arginine becomes conditionally essential. When the body is stressed, such as recovering from a disease or it is exposed to inadequate nutrition, the requirements for arginine are increasing and the body cannot produce enough.

Raising arginine concentrations through a diet can help treat hair loss. This is especially valid if it is a symptom of a basic health problem.

Good sources of food for arginine include milk, fish, beef, chicken, oats, sesame seeds, chick peas, soy, granola, pumpkin seeds, sunflower seeds and nuts.

About a quarter of keratin is produced from this cysteine.

Several studies have confirmed that cysteine ​​supplementation can reduce the symptoms of androgenic alopecia 3.

It is also an essential amino acid in the production of antioxidant glutathione.

Thus, cysteine ​​indirectly helps protect hair follicles from oxidative stress.

Like arginine, the body produces its own cysteine.

However, including cysteine-rich foods in your diet will ensure that this important amino acid is not lacking.

Ideal food sources include poultry, pork, milk, legumes, broccoli and whole grains.

The other major component of keratin is methionine. This amino acid is also essential for the synthesis of a collagen precursor known as procollagen.

As an antioxidant, methionine also helps protect hair follicles from oxidative stress. Studies have shown that low concentrations of methionine cause a decrease in hair health and their growth decreases4.

Other studies show that this amino acid can also play an important role in slowing down the hair’s gray as well as hair thinning.

Because the body is unable to produce this essential amino acid, you must include in the diet high in methionine.

Good food options for methionine include fish, eggs, seeds, leafy vegetables, broccoli, zucchini, pumpkin and nuts.

This essential amino acid helps stimulate collagen and is important for repairing damaged hair. The hair follicles also require the proper functioning of lysine. Studies have shown that hair loss can be reduced with the addition of lysine 6

Ideal sources of food for lysine include fish (mainly salmon, sardines and roast), dairy, poultry, red meat, pork, legumes, nuts, spirulina and legumes.

Glycine helps fight hair loss

One of the smallest and most common amino acids, glycine is very important for the digestive and central nervous system.

More importantly, it also helps in the production of collagen.

The body can produce this amino acid itself. You can also get protein-rich foods like fish, meat, milk, soybeans, spinach, cabbage, beans, kale, banana and kiwi fruit.


This non-essential amino acid helps in the production of collagen and cartilage, as well as the maintenance of muscle tissue. The best sources of food for proline include meat, milk, eggs, asparagus, avocado, beans, broccoli, spinach, legumes and soybeans.

The 9 leading amino acids for hair growth

Here’s a weird thing I’ve noticed about people – they will attack their hair with any oil, hair mask, shampoo and conditioner that they can grab from their pharmacy or kitchen to get long, shiny hair. But the only thing they won’t notice is their diet. What most of us fail to understand is that good nutrition plays just as important a good hair care routine when it comes to hair growth. And one range of nutrients we need to keep our hair healthy and increase hair growth is amino acids. Read on to know how amino acids for hair growth work.

Amino acids for hair growth – amino acids corner

What are amino acids, you ask? Well, amino acids are organic compounds composed of believers, carboxylic acid, and a side chain specific to each amino acid. Simply put, they are the building blocks of the protein that makes up the fifth of the human body. It is therefore not surprising that amino acids play a vital role in all our biological processes, one of which happens in the case of hair growth.

How Do Amino Acids Improve Hair Growth?
To understand how amino acids improve hair growth, we must first understand the composition of the hair itself. About 88% of your hair is made up of keratin protein. For our bodies to produce keratin, it needs 18 different types of amino acids. While some of these are produced by our bodies, others should be added to our diet. A proper level of these amino acids in our bodies leads to optimal production of keratin, which in turn increases hair growth. Furthermore, amino acids play a major role in the production of red blood cells that provide nutrients and oxygen to the hair follicles, thereby facilitating hair growth.

Now you’re probably wondering exactly which amino acids you need to add to your diet to boost your hair growth. So, without paying any further attention, let’s jump right into it!

The 9 leading amino acids for hair growth
Although there are about twenty different types of amino acids that play an important role in the healthy functioning of your body, here are the top 9 essential for hair growth.

1. Cysteine

Cysteine ​​is by far the most important amino acid for hair growth. Not only does it facilitate healthy hair growth, this amino acid also helps stimulate new hair growth. Cysteine ​​is a powerful antioxidant that protects hair from sun damage and other harmful radiations. Furthermore, it has been found to treat alopecia symptoms. And as if that were not enough, it also provides sulfur for hair cells to enhance their texture and strength.

Best sources of cysteine: The main sources of nutrition for cysteine ​​include broccoli, chicken, wheat germ, Brussels sprouts, and some dairy products such as milk and yogurt.

2. Methionine

Methionine is another essential amino acid for hair growth. This amino acid is a strong antioxidant and a storehouse of sulfur, a key component in the fight against hair disorders. Methionine is a good lipotropic as it helps break down fat and prevents fat accumulation in specific arteries and body areas. This methionine functionality increases the blood supply to the hair follicles and scalp, further leading to hair growth. This amino acid also plays a role in the collagen synthesis responsible for strengthening the hair shaft.

Best sources of methionine: Fish, eggs, Brazil nuts, grains and sesame seeds are good sources of methionine.

3. Lysine
Lysine helps to create collagen by absorbing calcium. This collagen, as it is known, is essential for creating the basic structure of hair follicles, for strengthening hair shafts and for strengthening hair growth, in general. Lysine also stops lowering testosterone for DHT, which is the main cause of androgenic alopecia (male pattern baldness).

Best sources of lysine: Chicken, eggs, fish, red meat, legumes, nuts, legumes, red meat, pork and dairy are excellent sources of lysine.

4. Glycine
Glycine is another amino acid that plays an important role in the production of collagen necessary for hair growth. Glycine also plays a vital role in the effective functioning of the digestive and central nervous system. This means it protects the body from nerve disorders that can cause hair loss.
