Biological hair shape change composition and kit, and method for changing hair shape

A biological hair shape change kit, comprising:

• a macromolecular component, comprising:
• a protease belonging to the class of alkaline proteases;
• a small molecular component, comprising:
• a peptide with reduction activity;
• an alkali agent component;
• and
• at least one packaging container for containing the macromolecular component, the small molecular component and the alkali agent component,
• wherein both the macromolecular component and the small molecular component are obtained from a fermentation product of Bacillus licheniformis and a keratin and/or keratin polymer-containing medium,
• wherein molecular weights of ingredients in the macromolecular component are greater than or equal to 3 kDa and are 3-1000 kDa, and molecular weights of ingredients in the small molecular component are less than 3 kDa and are 0.01-2.99 kDa, and
• wherein the biological hair shape change kit is used in the form of a mixture of the macromolecular component, the small molecular component and the alkali agent component.
