You can work as a hairdresser if you have hepatitis B. Daily contact does not lead to the transmission of hepatitis B. Hepatitis B is transmitted through sexual intercourse, blood, and vertical transmission from mother to child. Therefore, people with hepatitis B can work in the barber industry, but they should try to avoid any close contact with clients, such as shaving, tattooing, etc., so as not to cause hepatitis B transmission. If you are suffering from hepatitis B, it is also recommended that you should take active treatment to minimize the number of replication of the hepatitis B virus. You can use medication, such as entecavir and interferon, which can inhibit the virus in your body, but you should use the medication correctly when using the medication under the guidance of your physician. Patients should also improve their lifestyle, eat more fresh fruits and vegetables, exercise moderately, and get enough sleep. Regularly go to the hospital for follow-up, under the guidance of the doctor, improve the relevant examination, clarify the condition, and be systematic and regular treatment.
