Hair oil thinning hair loss is considered to be seborrheic alopecia, which can be treated by topical medication, oral medication, hair transplantation and so on. 1. Topical medication: Minoxidil tincture is preferred, which can stimulate hair growth, but it needs long-term use, about 6 to 9 months to work. Some of them will aggravate hair loss and return to normal after a period of time. 2. Oral medication: male patients can take Finasteride orally, female patients can take spironolactone orally, which can antagonize androgens, thus improving hair loss. 3. Hair transplantation: Hair from non-hair loss areas such as the occipital region can be transplanted to the thinning areas. Hair loss may continue in the non-transplanted area, so medication is needed. If the above situation occurs, it is recommended to go to the hospital in time to receive standardized diagnosis and treatment, and the above medication should be used according to the doctor’s prescription.
