Stock up and save on your favourite hair treatment with this value double pack. Utilising a holistic approach to support healthy hair from the inside out, Density Amino Acid Protein Booster has been Trichologically formulated to contain key nutrients that support in the maintenance of healthy hair. Each serving contains a blend of essential and non-essential Amino Acids, including Lysine, Leucine, Methionine, Valine and Cysteine. Density Amino Acid Protein Booster is designed for those wanting to ensure they receive the correct daily quota of Amino Acids to support the maintenance of healthy hair. It is especially beneficial for those following vegan or vegetarian diets, as some Amino Acids can be more difficult to obtain through non-animal food sources. Hair health can be impacted by many different factors, including poor nutrition, hereditary influences, stress, medication, over-styling, and chemical treatments. 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. Formulated to contain key nutrients, using a holistic approach to support healthy hair from the inside out.* *This statement has not been evaluated by the Food and Drug Administration.
