It is normal to experience some hair fall while shampooing. Individuals can lose around 50-100 hairs daily during natural hair growth. This includes the strands that fall out during shampooing. If you notice a slightly higher amount of hair fall during showering, there's generally no cause for concern. However, you see a significant increase in hair fall or bald patches. In that case, seeking professional advice from a hair care specialist or dermatologist is advisable to rule out any underlying issues.
