7 Top Amino Acids for Faster Hair Growth

Sharing is caring!

The Most Important Amino Acids for Hair Growth

Our hair today is just not what it used to be. Dry, fragile strands that simply refuse to stay on your head are the norm. Men and women everywhere are resorting to radical measures to make their hair better but in vain. There are many known causes of hair loss, however, the commonest culprit seems to be the food we eat. The usual diet of an average person today lacks major nutrients that are required for hair growth. One of the essential constituents is the amino acid group. The importance of these nutrients can be realized by the fact that hair is basically made up of protein, which is of course made by amino acids. There are more than 20 amino acids, but research has proven the role of 7 of these for hair growth and repair.

The different amino acids include:

  1. Cysteine
  2. Lysine
  3. Arginine
  4. Methionine
  5. Glycine
  6. Proline
  7. Taurine

Each of them has their own role in promoting hair growth. Some can be made by the human body itself, but some like methionine and lysine are not. These amino acids are the essential amino acids, which need to be provided in the diet. If they are not included in food, the body enters a deficient stage with varied effects that include restarted hair growth, dry and brittle hair and dry skin.

Hair is basically made of the protein keratin and collagen. Both of them are actually proteins made up of a range of amino acids. Collagen is basically made up of lysine, methionine, glycine and proline. As collagen is essential for the strength of the hair, these 4 amino acids are definitely vital for strong hair and hence for promoting good hair growth. Collagen is also necessary for the scalp, for anchoring the hair in its follicle. Inadequate consumption of these amino acids leads to poor anchoring of hair and ultimately frequent hair fall. It also affects the strength of the individual hair strand leading to breakages and the horrible split ends that everyone dreads.



Aside from this, each amino acid also has its own individual functions. Coming to the first one, cysteine is by far the most important amino acid for hair growth. This is because it has a number of functions associated with promoting healthy hair. This includes:

  • Stimulates new hair growth, to increase the quantity of hair
  • Potent antioxidant protects the hair from damaging radicals in the air and also from the damaging rays of the sun
  • Source of Sulphur, which functions to increase the strength of hair and also adds texture

Due to these roles, cysteine is necessary for maintaining healthy hair growth and can be easily found in foods like broccoli, chicken, and dairy products like milk and yogurt.


2. Lysine

One of the important amino acids worthy of separate mention is lysine. This amino acid cannot be made in the body and hence, is an important constituent of the diet. Its role in collagen formation highlights its importance in healthy hair growth. However, there are other ways in which this amino acid promotes healthy hair. The many different functions of lysine in favor of hair growth include:

  • Building block of collagen – the important hair protein needs lysine as one of its important constituents. Besides this, lysine also acts a stimulator of collagen, hence playing its role in strengthening hair.
  • Promotes absorption of iron from the intestine – iron plays an important role in promoting hair growth. Iron also increases the oxygen carrying capacity of blood, which helps deliver better oxygen to the scalp to promote hair growth.
  • Promotes zinc absorption from the intestine – zinc is necessary for the production of many enzymes and plays a vital role in the maintenance of healthy strong hair.
  • Nourishes hair follicles – making the base of the hair strong to allow for less breakage. The stronger base means stronger strands which will lead to healthier hair.

There are many sources from where you can get abundant quantities of lysine. These include fish such as salmon, sardines, and cod, milk products like cheese, butter, and yogurt, red meat, and nuts, legumes, and pulses making it extremely easy to include in your diet.


3. Glycine

Glycine, on the other hand, has its own story to tell. It plays a significant role in hair growth and is one of the easily accessible amino acids in the body. This is because it can be made by our bodies and is the simplest amino acid as well. Being simple doesn’t mean it has any fewer functions. On the contrary, glycine plays its part in a number of places to promote healthy hair growth, which include:

  • Component of collagen – the amino acid is used to make collagen, which is necessary for strengthening hair.
  • Reduces hair loss associated with nerve disorders – this can be attributed to its function in the nervous system where it helps replenish neurotransmitters and prevents many adverse effects of nerve disorders.
  • Stimulates growth hormone secretion – the hormone has a central role in the promotion of overall growth and hair production. The hormone maintains the critical balance necessary for great hair growth.

Although glycine can be made by the body, nutritionists advocate its presence in a balanced diet. For hair growth, you need to make sure that your diet contains abundant quantities of this amino acid. You can do this by eating lots of spinach and cabbage, pumpkins, bananas, high protein foods and dairy products, all of which house abundant quantities of this amino acid.


4. Proline

Moving on, proline deserves special mentioning in our list of necessary amino acids for healthier hair. This is because, like the others mentioned, proline also has its own role to play in promoting hair growth. This includes:

  • Constituent of collagen – the amino acid is one of the 3 necessary constituents of collagen, making it necessary for the promotion of strong and healthy hair.
  • Necessary for repair – it helps to repair any damage to the skin and scalp. It also functions in replacing and renewing the day to day damage in tissues. This allows it to promote a healthy environment for hair growth.
  • Healthy skin – proline is A necessary constituent of healthy skin. It makes the skin thick and elastic and also adds to its ability to resist infection. This promotes healthier hair by providing better conditions for hair growth.

Proline can be made by the body, however, for good hair growth, it is advisable that you include it in your diet. Reliable dietary sources of the amino acid include meat, dairy products, and eggs.


5. Methionine

Methionine is another critical amino acid involved in promoting luxurious hair growth. Aside from its role in forming collagen, methionine is also

  • Strong antioxidant, working to rid the scalp of harmful bacteria and promoting scalp health. It Serves as a shield against the damaging rays of the sun, rejuvenating hair wherever necessary.
  • Sulfur content, which is needed to prevent a variety of hair disorders and promote healthy strands.
  • Increases blood supply to the scalp, which helps provide nutrients to the hair, promoting healthy hair strands.

The amino acid is clearly one of the key ones involved in hair growth and is abundant in fish, eggs, sesame seeds, Brazil nuts and cereal grains. This goes to show how easy it is to incorporate these nutrients into your daily diet.


6. Arginine

One other amino acid that is essential is arginine. This miraculous amino acid has great benefits for the hair. It has multiple roles in the body that work together to promote hair growth which include:

  • Increased blood supply to the scalp, as it is a nitric oxide precursor it results in increased levels of nitric oxide that in turn stimulate potassium channels. These channels cause dilatation of blood vessels and hence an increased blood supply to the scalp, resulting in the delivery of nutrients to the hair.

The amino acid can be produced by humans, but it is also present in a number of nuts including cashews, hazelnut, coconut, as well as sesame seeds, sunflower, and fish.


7. Taurine

Besides these, a special and somewhat different amino acid is taurine. The amino acid plays its role in promoting hair growth by its features that include:

  • High content of sulfur, that is necessary for hair growth and healthy functioning of enzymes. It also prevents the breakdown of hair follicles so that the hair roots keep strong and healthy.
  • It is concentrated in hair bulbs and works to strengthen the strands to ensure that hair does not end up being weak and thin.

Although it can be produced by the human body, its increased demands may result in as relative deficiency. To avoid these times, it’s better to have a good source of the amino acid included in your diet. Good sources of taurine include marine animals, meat and breast milk. Energy drinks and infant supplements are also fortified with this amino acid.

All in all, correcting one’s diet is an essential step towards healthier hair. Yes, our body can make most of these building blocks, but the increased demands of our systems shift us towards a relative deficiency. This is why it is important to not only include the essential amino acids in your diet but all the rest as well. Come to think of it, when they are so readily available in the usual foods, it isn’t hard to get your hands on them. All you need to do is revamp your diet, and you are good to go. So, before you run off trying radical measures to Promote hair growth, give your diet a review. Maybe, the real problem can be corrected by just a diet change.
