Is your hair limp and weak? Does it break and easily fall off? You could be low on amino acids! While we usually focus on iron, vitamins and nutrients, the role of amino acids for hair growth is lesser-known to us. These are called building blocks of hair, which are crucial to maintaining a healthy and voluminous mane.

In this article, we shall uncover the names of essential amino acids required by your hair, and also find out how each of them contributes to hair growth. But before that, lets’ understand the link between amino acids and human hair.

What Are Amino Acids and How Do They Benefit Our Hair?

To understand if Amino acids are good for hair, we need to understand what these agents are. Our hair is largely composed of a protein called Keratin. Absence or reduced levels of this agent can destroy the structure of your hair and cause hair loss due to breakages. Keratin is made up of amino acids, which can be sourced from different foods and supplements. These nutrients play a critical role in strengthening your hair, improving its elasticity and also aid in better blood circulation. By doing so, they prevent loss of hair due to damages.

Top 6 Amino Acids for Hair Growth:

Amino acids are categorised into two groups – essential and non-essential. The essential amino acids are those who cannot be generated by the body and must be derived from external sources. Non-essential amino acids can be produced internally from other nutrients. Among them, certain amino acids are critical for hair regrowth. Here are the details:

1. Glutamine:

Glutamine is one of the key amino acids which contributes to steady hair growth in humans. Although it is produced naturally by the body, the production gradually declines with age. This is the reason why the rate at which our hair grows slows down for middle-aged and older people. It is advised to increase the intake of protein foods like eggs, vegetables, lentils, etc., to balance the levels of Glutamine.
