1. Observe the color and texture of hair: healthy babies' hair usually presents natural colors, such as black, brown or gold. If the hair color is abnormal or there is obvious color difference, further inspection may be needed. In addition, healthy baby's hair should be soft and shiny, while dry, fragile or dull hair may indicate malnutrition or other health problems.
2. Pay attention to the health of the scalp: A healthy baby's scalp should be clean, non-inflammatory and tasteless. If you notice scalp redness, itching, desquamation or abnormal secretion, it may be a sign of scalp problems, such as dandruff, eczema or infection.
3. Observe the growth rate of hair: The growth rate of normal baby's hair varies from person to person, but it generally increases by about 0.5- 1.5 cm per month. If you notice that your baby's hair growth rate is obviously slowing down or stagnant, you may need to consult a doctor to rule out potential health problems.
4. Pay attention to hair loss: healthy babies' hair usually doesn't fall off a lot. If you notice that your baby's hair is obviously thinning or falling off, you may need to consult a doctor to determine whether there is hair loss.
It should be noted that the above are just some common indicators and precautions, and cannot be used as a basis for diagnosis. If you have any questions or concerns about your baby's hair, you'd better consult a pediatrician or dermatologist for further evaluation and suggestions.
