The Benefits Of Amino Acids For Your Hair

Everybody sheds a small amount of hair every day. This normal cycle allows hair cells to generate themselves.

Keratin, a protein that consists of amino acids, is responsible for promoting hair growth.

Amino acids are not just found in hair cells—they are in every cell of our body. However, the body cannot produce some types of amino acids. These can only be obtained from certain foods.

Read on to find out about the benefits of amino acids for your hair.

Who Is Amino Acids For?

Everyone requires amino acids. The cells in the body consist of proteins and amino acids play a critical role in the creation of proteins.

While there are hundreds of amino acids, only 20 are found in the body and nine out of those amino acids are obtained from our diet.

Because of the important role amino acids play in the proper functioning of the body, it is important to obtain enough amounts from the food we take or from supplements.

How Do Amino Acids Help With Hair Growth?

Amino acids can be particularly helpful if your hair usually grows slowly or if you have thinning hair.

Methionine and lysine are the essential amino acids concerned with hair growth—they are the building blocks of the protein keratin.

Lysine also promotes the production of collagen. At the same time glutamine and arginine, both non-essential amino acids are important for hair growth.

The human body only produces a small amount of these amino acids and production slows further with age. Taking supplements of all four amino acids can boost hair growth.

In addition to being major building blocks for the protein keratin, amino acids also play a key role in creating red blood cells. Red blood cells transfer oxygen to the hair follicles to promote healthy hair growth.

While amino acids can help with hair growth, some conditions may not benefit from these building blocks. For instance, amino acids cannot help with male baldness.

Intake of amino acids may help with temporary hair loss caused by factors such as pregnancy, genetics, hormonal changes, and stress. However, it is important to note that this is not a miracle cure.

What amino acids will do is promote natural growth of your hair to its maximum potential.

How To Increase Amino Acid Intake

Your diet can help boost the amount of amino acid the body requires for healthy functioning and for hair growth.

Consider including leafy greens, legumes, seeds, cheese, lean meats, eggs, fish, and nuts into your diet. These foods are rich in essential amino acids lysine and methionine.

Amino acid supplements can also help to support hair growth.

How To Choose an Amino Acid Supplement

There are numerous brands of amino acid supplements available on the market. The first thing to look out for is a supplement that specifically promotes hair growth.

Amino acid supplements come in liquid or capsule form. Both types work equally well and your choice will depend on personal preference.

When choosing amino acid supplements for hair growth look for those containing ingredients such as vitamins and biotins.

Others contain herbs, which also support hair growth. What’s really important is to go for an amino acid that is simple, pure, and is as natural as possible.
