Does a 2-month-old baby's hair grow more slowly on the part of the head that is pressed during sleep?

Generally speaking, whether a 2-month-old baby's hair grows more slowly in areas where pressure is applied during sleep depends on the development of the baby's hair follicles. If the baby's hair follicles are underdeveloped, this situation may occur; however, if the hair follicles are fully developed, such an issue typically does not arise. If any physical discomfort occurs, it is recommended to seek medical attention promptly and receive treatment under the guidance of a qualified physician. The detailed explanation is as follows:

When a 2-month-old baby’s hair follicles are not yet fully developed, localized scalp pressure may impair blood circulation, thereby restricting the supply of nutrients needed for normal follicle growth and development. In such cases, hair in the pressured area may grow relatively slowly.

If the hair follicles of a 2-month-old baby are already well-developed, even if certain areas of the scalp experience pressure, there is usually little impact on the rate of hair growth. This is because mature hair follicles possess strong self-repairing abilities and adaptability, enabling them to withstand temporary pressure and minor circulatory disturbances.

In daily life, regularly changing the baby’s sleeping position and improving the sleep environment can help reduce prolonged head pressure. Pay close attention to the baby’s hair growth patterns, and if any abnormalities are noticed, seek medical evaluation promptly.
