Keratin is not a biotin. Keratin is a protein that makes up the structure of hair, skin, and nails. Biotin, also known as vitamin B7, is a vitamin that plays a role in the production of keratin.
In other words, biotin is a building block for keratin. It helps your body make keratin, but it's not the same thing as keratin.
Think of it this way: You need bricks to build a house, but bricks aren't the house itself. Biotin is like the brick, and keratin is like the house.
In conclusion: Keratin and biotin are not the same thing, but they work together to promote healthy hair, skin, and nails.
