    Glossary Irritation

    state of inflammation or discomfort in body tissues

    Irritation refers to a state of inflammation or discomfort in a part of the body, often caused by external factors like chemicals, physical abrasion, or allergens. In the context of the scalp and hair, irritation can manifest as redness, itching, or a burning sensation, potentially leading to conditions like dermatitis or exacerbating hair loss issues such as alopecia.
