How much hair do hairstylist ingest?

On average, hairstylists can ingest a small amount of hair during their work due to hair clippings and styling products. While exact figures vary, studies suggest that hairstylists may ingest approximately 0.5 to 1 gram of hair per year. However, this amount is generally considered negligible and not harmful to health. Proper hygiene practices and workplace cleanliness can further minimize any hair ingestion.
