Temporary early hair fall that can occur after starting minoxidil.
Minoxidil shedding is a common anxiety trigger. Some people notice increased hair fall during the first few weeks of treatment. This can happen because hairs that were already near the end of their cycle are shed as follicles shift towards a new growth phase. It is usually temporary and does not mean the treatment has failed. That said, not every shed is harmless: severe shedding, scalp inflammation, patchy loss, or shedding that continues for months should be reviewed. Clear expectations help patients avoid stopping treatment too early.
