Diet Impact: the Importance of Protein

25 Oct

Hair is composed of keratin proteins. Amino acids are the building blocks of proteins. Hair is composed of 20 amino acids. A poor diet can potentially still allow your hair to grow at a normal rate, but a lack of protein in your diet can slow down or stop your hair growth altogether; your hair could even start to shed.

There are four key amino acids needed to produce keratin protein (i.e. produce hair): cysteine, lysine, arginine and methionine. Methionine and Lysine must be sourced from our diet. Arginine and Cysteine can be synthesised by the body. But if your nutrition is poor, their levels will be low. A quarter of our keratin is made of Cysteine. By increasing the availability of those 4 amino acids, it’s possible to combat hair loss and stimulate new hair growth.
