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. Density Amino Acid Booster has been Trichologically formulated to contain key nutrients, using a holistic approach to support healthy hair from the inside out. Each serving contains a blend of essential and non-essential Amino Acids, including Lysine (394.2mg), Leucine (492.5mg), Methionine (197mg), Valine (246.3mg) and Cysteine (170.7mg). - Improves hair condition - Vegan and vegetarian To use: Take two capsules, twice a day.

Philip Kingsley’s bottles and tubes are crafted from either sugarcane bioplastic or Post-Consumer Recycled (PCR) plastic. Sugarcane bioplastic is the first plastic ever made from a fully renewable origin, and, even better than this, to make it they actually reduce the world’s carbon in the process. PCR plastic reuses single-use plastics (such as drinks bottles and packaging) which would otherwise be disposed of in landfill sites, greatly reducing landfill waste and plastic pollution. It also uses less energy and fossil fuels, protecting the environment from excess pollution, greenhouse gas emissions, and overuse of resources.
