If hair loss resumes after a period of improvement, it is recommended to first analyze the possible causes and then take corresponding measures based on the findings. These measures may include maintaining a healthy lifestyle, keeping a positive mood, and using proper hair care methods.

Here are some possible reasons for hair loss and corresponding treatment methods:

  1. Normal Physiological Hair Loss: Hair growth is cyclical, with each strand having a lifespan of about 2 to 6 years before naturally falling out and being replaced by new hair. Therefore, even after a period of hair growth recovery, new hair may start to fall out. This situation usually does not require special treatment. Maintaining a healthy lifestyle and proper hair care practices should suffice.

  2. Nutritional Deficiency: Hair growth requires adequate nutrition. An unbalanced diet or a lack of certain key nutrients can lead to hair falling out again after a period of recovery. In such cases, it is recommended to continuously use hair loss prevention products (such as anti-hair loss shampoos and hair growth serums).

  3. Dietary Adjustments: It is advisable to adjust your diet to include more foods rich in protein, vitamins, and minerals, such as lean meats, fish, beans, nuts, and leafy green vegetables.
