Amino Acids For Healthy Hair And Its Benefits

Healthy hair is like a crown that adds a touch of beauty to every woman's appearance. Healthy hair not only enhances a woman's physical beauty but also boosts her confidence and radiance. Moreover, healthy hair reflects overall well-being, signaling to the world that she takes care of herself from the inside out.

One of the most effective hair care supplements in the market are amino acids for hair growth supplements. But have you ever wondered what these amino acids are and what they do to your hair? How effective are amino acid hair products? Today, we will help elaborate on what, why, and how amino acids are important for hair growth and hair health.

What are Amino Acids?

Amino acids are the fundamental molecules that constitute proteins, vital for various biological functions like muscle building and enzyme production. There are 20 standard amino acids, categorized into essential (not synthesized by the body) and non-essential (synthesized internally). Essential amino acids include lysine, valine, and tryptophan, while non-essential ones include alanine and glutamine. The best source of amino acids varies but includes animal products like meat, fish, eggs, and dairy, as well as plant-based sources like beans, nuts, seeds, and grains. Consuming a diverse diet ensures adequate intake of all essential amino acids for optimal health.

Best Amino Acids for Hair Growth


Cysteine plays a vital role in promoting hair growth as it aids in the stimulation of new hair growth. Additionally, cysteine acts as a powerful antioxidant, protecting the hair from damaging effects caused by sunlight and other harmful radiation. Research indicates that cysteine may be effective in alleviating symptoms associated with alopecia. Moreover, cysteine contributes sulfur to hair cells, resulting in improved texture and strength.

Tyrosine is responsible for the creation of melanin which is responsible for hair colour. It is also responsible for regrowing stronger hair. Deficiency of tyrosine can cause stress induce hair loss. L-Tyrosine functions as a natural ally within our body, facilitating communication with the thyroid and assisting in the regulation of crucial hormones in the thyroid, pituitary, and adrenal glands. (2)


Methionine, a crucial amino acid for promoting hair growth, is known for its antioxidant properties and high sulfur content. Sulfur is essential for addressing hair disorders, while the amino acid's ability to enhance blood circulation to the scalp and hair follicles aids in stimulating hair growth. Additionally, there are anecdotal accounts indicating that methionine contributes to collagen synthesis, which strengthens the hair shaft. (3)


Proline is an important amino acid for hair growth. Proline helps in collagen formation. Collagen is a vital part of protein structure that forms the structure of our hair strands. Proline also aids in wound healing and maintaining the health of the scalp, fostering an optimal environment for hair growth. (4)


Lysine plays a crucial role in the creation of collagen by absorbing calcium. Collagen is essential for the development of the foundational structure of hair follicles, enhancing hair strength, and promoting hair growth. Additionally, Lysine is believed to hinder the conversion of testosterone into DHT by inhibiting 5-alpha reductase, which is the primary cause of androgenetic alopecia (male pattern baldness). (5)


Arginine, also known as L-Arginine, is a precursor to nitrogen oxide. Arginine helps to open potassium channels within cells which facilitates the movement of blood vessels and improves circulation. Enhancing blood circulation has the additional benefit of increasing the supply of blood to the hair follicles, thereby promoting hair growth. This amino acid, although not essential, can be found in various food sources like fish, coconut, sesame seeds, hazelnuts, and cashews. (6)


Glycine, a non-essential amino acid, supports hair growth by aiding in the synthesis of collagen, a key structural protein in hair follicles. Collagen strengthens hair strands and improves elasticity, promoting healthy growth. Additionally, glycine helps maintain the health of the scalp and supports the production of antioxidant enzymes, fostering optimal conditions for hair growth. (7)


Amino acids play a crucial role in enhancing hair health and promoting hair growth. They are the building blocks of proteins, which are essential for strong and healthy hair. Certain amino acids, such as cysteine, methionine, and lysine, are particularly important for hair growth and can be obtained through a balanced diet or supplements. Including foods rich in these amino acids, such as eggs, fish, legumes, and nuts, can help improve the quality of your hair.


What amino acid helps hair grow?

Amino acids like cysteine, methionine, arginine, lysine, proline, tyrosine and glycine helps in hair growth.

Can a deficiency of amino acids cause hair loss?

Yes, amino acids are essential to produce keratin, the protein that makes up hair. A deficiency in certain amino acids, such as cysteine and methionine, can lead to weakened hair strands and increased hair loss.

Which amino acid helps hair grow faster?

Amino acid cysteine plays a crucial role in hair growth and strength. It promotes the production of keratin, which is essential for faster hair growth and improved hair quality.

How to get thicker hair?

To promote thicker hair, maintain a balanced diet rich in vitamins, minerals, and proteins. Use gentle hair care products, avoid excessive heat styling and chemical treatments, massage your scalp regularly, and consider supplements like biotin or collagen to support hair health.

How to increase hair volume?

To increase hair volume, use volumizing shampoos and conditioners, avoid heavy products that weigh hair down, blow-dry hair upside down for added lift, consider using volumising styling products, and incorporate regular haircuts to remove split ends and add shape and fullness.
