Hair Stops Growing: Causes and Solutions

Hair stops growing when the anagen growth phase shortens, leaving strands stuck at one length; most follicles become dormant rather than die, so regrowth is often possible. Key causes include nutritional gaps in iron, zinc, biotin, and protein; chronic stress; hormonal shifts; scalp inflammation; and over-processing. Blood tests and a root-cause approach are recommended before topical treatments. A healthy scalp with good circulation supports growth. Reducing tight hairstyles, heat, and chemical use, plus managing stress and protein intake, can help restore the cycle.
