Question
A parent inquired about an 80-day-old baby who experienced hair growth on the top of the head after a haircut, but no growth was observed at the back of the head, worrying whether this was due to a calcium deficiency.
Answer
Based on the parent’s description, the baby may be showing signs of calcium deficiency. When children are deficient in calcium, they may exhibit restlessness during deep sleep, moving their heads back and forth, which can lead to hair loss at the nape of the neck. It is recommended that parents provide the baby with cod liver oil drops and expose them to sunlight moderately when it is not too strong, ensuring to shield the baby’s eyes during sun exposure.
