Can pregnant women use a hair dryer after washing their hair?
Generally speaking, pregnant women can use a hair dryer after washing their hair, but they should control the duration appropriately. The detailed explanation is as follows:

After washing their hair, pregnant women may require a long time for their hair to dry naturally. Using a hair dryer can help dry the hair quickly, preventing colds caused by prolonged dampness. Additionally, using a hair dryer promptly dries the hair, reducing the time the scalp remains wet, which minimizes the chance of bacterial growth and helps maintain personal hygiene. As long as precautions are taken—such as avoiding excessively high temperatures, not directing the airflow straight onto the scalp to prevent burns, and using a gentle airflow at an appropriate distance—a hair dryer can be used safely. The duration of hair dryer use should also be limited to avoid irritation to the scalp and potential adverse effects on hair follicle health.
During pregnancy, it is important to maintain personal hygiene and keep the hair clean by choosing suitable shampoo and hair care products, which helps support scalp health. Adequate rest, healthy lifestyle habits, and a light diet are also beneficial for overall health.
