Did you mean Mechanical Stress?

Glossary Mechanical Stress

physical forces exerted on hair or scalp causing damage

Mechanical stress refers to the physical forces exerted on hair strands or the scalp, which can lead to damage or hair loss. This can occur from actions like tight hairstyles, frequent brushing, or the use of harsh hair accessories. For professionals, understanding mechanical stress is crucial for advising patients on hair care practices to prevent traction alopecia and other forms of hair damage.
