Seborrheic alopecia is a common scalp problem, mainly caused by excessive oil secretion in the scalp. Here are some suggestions:

1. Keep your scalp clean: Wash your hair every day with warm water and mild shampoo, and gently massage your scalp to help remove excess oil and dirt.

2. Avoid over-stimulating the scalp: Try to avoid using overheated water to wash your hair, and do not over-comb your hair or use products that irritate the scalp such as essential oils.

3. Diet conditioning: Maintain healthy eating habits and take in balanced nutrition. It is recommended to increase foods rich in vitamins A, B, C, E, zinc, copper and other trace elements, such as fruits, vegetables, nuts, fish, etc.

4. Massage your head appropriately: Massaging your head moderately every day can promote blood circulation in the scalp and help regulate secretion.

5. Avoid using too much hair spray, styling spray and other chemical products to reduce irritation to the scalp.

6. If the above methods are ineffective, you can seek advice from a professional doctor or dermatologist. They may give further treatment options based on individual circumstances, such as scalp disease treatment, hormone therapy, etc.

It should be noted that seborrheic alopecia is a chronic disease with no cure, but with correct care and treatment, hair loss can be effectively controlled and slowed down.
