Video transcript

Hair does not know it has been cut. Hair is composed of dead cells and lacks nerves or a feedback mechanism to the brain. Cutting hair doesn't cause pain or alter its growth cycle. Hair growth originates from follicles beneath the scalp, which remain unaffected by cutting. To maintain a desired style, consider trimming hair every 6-8 weeks, promoting healthy ends without influencing how hair behaves or grows. Regular trims can maintain hair health and appearance.
