Scraping is a diagnostic as well as therapeutic procedure in obstetrics and gynecology, where the endometrium is scraped to provide diagnostic and therapeutic results. There are no significant restrictions on hair washing after curettage. In general, you can wash your hair after a curettage. However, it should be noted that patients may experience a weakening of the body resistance for a short period of time after curettage. Therefore, during this period, if washing hair requires the patient to pay attention to the following points: First, it is necessary to take good warmth measures to avoid catching a cold. If you catch a cold during this period, it is easy to have an upper respiratory tract infection. Second, pay attention to the temperature of the water used to wash hair. Too hot or too cold water temperature can cause discomfort and further weaken the patient’s resistance. Fourth, shorten the hair washing time. The patient will have slight lower abdominal pain symptoms after the curettage, so washing the hair for too long will trigger the aggravation of lower abdominal pain symptoms. And some patients are weak, poor physical fitness, long time hair washing may even cause the occurrence of shock. Finally, after scraping, patients can routinely take oral anti-inflammatory drugs to prevent infection treatment. Therefore, there is no obvious time limit for hair washing during curettage, and patients only need to pay attention to avoid getting cold.
