Many people ask me what proteins are most appropriate for hair growth . People with hair loss often turn to protein and amino acid supplements as part of their treatment regime . Although it is rare for a lack of protein to be a primary cause of hair loss , there is no harm in taking extra protein or amino acid supplements if you wish for your hair growth . If you take a blood test your serum total protein should be between 60 – 80 grams per liter . Less than this suggests a problem with protein intake . And you may take some of the protein supplements now available either as powder protein supplements or liquid protein supplements . Soya bean protein is considered good for hair growth but takes care not to take it in excess otherwise it can have some negative effect .
Much importance has been given to proteins for hair growth . Protein serves as the major structural component of all cells in the body , and functions as enzymes , in membranes , as transport carriers , and as some hormones . During digestion and absorption dietary proteins are broken down to amino acids which serve as the building blocks for the formation of structural proteins and functional compounds of protein such as enzymes and precursors of hormones etc . There are 20 amino acids in all which are required for the synthesis of proteins .
But out of which some of the amino acids cannot be synthesized by the body and are therefore are required to be taken as dietary amino acid supplements if you wish to take them to stimulate your hair growth . The amino acids : Phenylalanine , Valine , Tryptophan , Threonine , Isoleucine , Methionine , Histidine Arginine , Lysine Leucine are considered to be essential amino acids . But the distinction between essential and non-essential amino acids is not very clear , as some amino acids can be produced from others . For example , the sulfur-containing amino acids , methionine , and homocysteine can be converted into each other but neither can be synthesized de novo in humans . Likewise , cysteine can be synthesized from homocysteine , but not otherwise . So , for convenience , sulfur-containing amino acids are sometimes considered a single pool of nutritionally-equivalent amino acids .
Hair follicles require a constant supply of amino acids via the bloodstream to maintain hair growth . Hair follicles contain some of the fastest-growing and dividing cells in the body so their energy , vitamin , mineral , and amino acid consumption is high . If amino acids are lacking ,
