What is the reason for the hair standing upright on the baby's head?

Patient's question:

No

Doctor's answer:

There are several reasons why a baby's hair stands up:
1. Babies with straight-up hair often have a neurotic temperament, they tend to cry frequently, struggle to establish regular biological rhythms like sleep, eating, and bowel movements, sometimes constipated, sometimes diarrhea, often restless at night, crying in the middle of the night, varying milk intake, and easily getting agitated during caregiving such as diaper changes and bathing. For such babies, it’s important to start by cultivating a good daily routine, such as establishing regular sleep and bowel movement schedules, providing easily digestible and non-irritating foods, and being patient with the baby when they don’t do well. Through this loving care, the baby’s neurotic behavior will gradually improve or even disappear, and their hair will also become smoother.
2. Some babies’ hair stands up due to hair texture. If the hair is too coarse, it’s also more prone to standing up.
3. The contraction of arrector pili muscles in the scalp can make hair stand up. One possible cause is calcium deficiency. You can give your baby calcium and vitamin D supplements and let them get more sunlight. Try it and see. Give your baby calcium and vitamin D supplements and let them get more sunlight:
