Hair health can be impacted by multiple factors, such as poor nutrition, nutritional deficiencies, hereditary influences, stress, medication, over-styling, and chemical treatments, amongst others. Amino Acids are an essential component of healthy hair as they combine to form proteins used by the body to build tissue cells, including those of your hair, skin, and nails. These proteins form the building blocks of your hair, keeping it strong and healthy. In fact, up to 85% of your hair is composed of a protein called Keratin. Amino Acids are divided into two groups, essential and non-essential. Essential Amino Acids cannot be created by the body and must be continually obtained from your daily diet. Non-essential Amino Acids on the other hand, are synthesised by the body, mostly in adequate amounts.
