Can you cut your hair during pregnancy?
In general, it is safe for pregnant women to cut their hair. The detailed explanation is as follows:

Cutting hair involves only trimming external hair and does not affect the health of the pregnant woman or fetal development. Hair growth and health are primarily determined by genetics, nutritional status, and hormone levels, rather than whether the hair is cut short. Moreover, as pregnancy progresses, a woman's mobility gradually decreases, making washing and managing long hair more difficult. Cutting hair short can help maintain personal hygiene and reduce cleaning difficulties. Additionally, during pregnancy, long hair may absorb more nutrients—although this effect is relatively minor—shortening the hair can somewhat reduce its nutritional demands, thereby helping the mother better allocate nutrients to the developing fetus.
Pregnant women should also take precautions when cutting their hair: avoid sitting for prolonged periods, use safe hairdressing tools, and refrain from chemical treatments such as hair dyeing or perming to prevent any adverse effects on the fetus.
