Your article on composting human/animal hair does not address the possible contamination by chemicals on hair treated with chemicals, or hair from drug users. Can you tell us if those things can cause any problems?

Yes, you can compost human hair. Human hair is a rich source of nitrogen, which is an essential nutrient for plants. However, when it comes to composting hair that has been treated with shampoos and other hair products, it is important to consider the chemicals present in these products.

Most shampoos and hair products contain chemicals such as sulfates, silicones, and synthetic fragrances. These chemicals can potentially harm the beneficial microorganisms in the compost pile and affect the overall composting process. Additionally, some chemicals may persist in the compost and could potentially be harmful to plants when the compost is used as fertilizer.

To ensure safe composting, it is recommended to use hair that has not been treated with chemical products. If you do decide to compost hair that has been treated with shampoos and other products, it is advisable to use it in small quantities and mix it well with other organic materials in the compost pile. This will help dilute any potential harmful chemicals and minimize their impact on the composting process.

Ultimately, it is important to be cautious when composting hair that has been treated with chemical products and consider the potential risks to the compost and plants.
