We're all familiar with keratin - it's the protein we find in our hair, skin, and nails. The hydrolyzation of it means that it is made more water soluble and slightly positively charged so we can use it in our products. When we use a protein in a product, we are looking for it to do a few things, including film form, moisturize, and condition our hair. We are using the keratin here to add some strength to our hair and help it remain pliable.
Trametes versicolor is a type of mushroom that is being used in this application as it contains an enzyme called laccase. It is claimed that this "enzyme is capable of annealing disulphide bonds which help enhance hair strength" (Annealing is when a heat treatment alters the structure of a material.) You might remember from the post on lycopene that disulphide bonds give hair its shape, so strengthening those bonds means we are less likely to see breakage or weakness at those points.
I'm afraid I can't find much about this trametes versicolor in all my searches. It sounds very interesting, which is why I used it in my products.
I've been using the kera straightening and curls at up to 10% in my cool down phase. It's recommended for use in leave in conditioners and other products you might use while drying, straightening, or curling your hair with heated devices.
