Eyebrow tattooing is not allowed during menstruation because during menstruation, the body’s resistance decreases, the blood clotting function is poorer than that of non-menstrual period, and bleeding is easy to occur, so if you tattoo your eyebrows during menstruation, it is easy to cause localized bleeding or swelling, which will affect the effect of tattooing, and it is easy to increase the recovery period of tattooing your eyebrows in the future. In addition, if you are going to have surgery, such as abdominal surgery or tooth extraction, you should avoid the menstrual period. During the menstrual period, you should pay attention to rest, avoid labor, and pay attention to a light diet, avoid cold, spicy and stimulating food. Pay attention to the vulva clean and dry, avoid gynecological inflammation, avoid menstruation period coitus, so as not to cause the uterine cavity infection.
