Bleeding during a haircut does not usually lead to AIDS. This is because there is no possibility of HIV transmission as long as the haircutting tool does not carry HIV on it. But haircutting tools are generally recycled, so if the last person is a person with AIDS and also made him bleed, then this haircutting tool is covered with fresh blood, and then cut your own hair and also bleed, then there is a possibility of getting AIDS. But this possibility is relatively small, if such a situation arises, it is purely coincidental, so this belongs to a small probability event, from daily life, do not think this situation will occur. So bleeding during a haircut is not something to worry about. If you are worried, you can take an AIDS antibody test in three months’ time, and if you can test negative, you can rule out the possibility of infecting yourself with AIDS.
