What Are the Key Causes of Thinning Hair?

The key causes of thinning hair include various nutritional deficiencies, hormonal changes, and environmental factors.

• Nutritional Deficiencies: Lack of essential vitamins and minerals like iron, zinc, and vitamins D and B12 can lead to hair thinning. These nutrients play crucial roles in hair health, and their deficiency can disrupt the hair growth cycle, leading to shedding and reduced hair density.
