How Long Does It Take Human Ĥair To Decompose
Understanding What Human Hair Is Made Of: Human hair is made mostly of a protein called keratin. Keratin is strong and durable, which is why hair can handle heat, water, and daily wear. This strength also makes hair very slow to break down after it is shed or cut. Unlike skin or food, hair does not decompose quickly because it lacks moisture and nutrients that bacteria need to thrive.
