What is the reason why baby’s hair is sparse and grows slowly?

Thinning and slow-growing hair in your baby may be a combination of many factors, which may include genetics, quantity and quality issues, poor nutrition during pregnancy, abnormal hormonal levels, and other health issues. Genes inherited from parents are likely to affect the amount and growth rate of your baby\’s hair. Certain genes may cause hair thinning by affecting the hair growth cycle and shortening the lifespan of hair. In addition, some diseases can also be passed on genetically, such as congenital hair defects and other hereditary hair-related abnormalities. Quantity and Quality Issues Before the hair follicle can produce new hair, the old hair must shrink and fall out. If a person\’s androgen levels are too high, this process is accelerated, causing more hair to shrink and fall out. Babies may also be born with lower hair follicle density and fewer hairs, causing their hair to look thinner. In addition, some external factors, such as chemicals (such as shampoo or conditioner, etc.), sun exposure, blow drying, combing, etc., may also damage the quality of hair and affect its growth. Malnutrition during pregnancy If the mother eats an unbalanced diet during pregnancy or lacks necessary nutrients (such as protein, vitamins, minerals, etc.), the baby\’s hair growth may be affected. Because hair is primarily made up of proteins and other nutrients, these elements are transported to the hair follicles and used to create hair. Without adequate nutrients, hair cannot grow properly. Abnormal Hormone Levels Some hormonal abnormalities may also lead to insufficient hair growth in your baby. For example, thyroid problems are often related to hair quantity and slow growth. In addition, endocrine disorders may also affect the levels of female and male hormones, thereby affecting hair growth. Other health problems Some health problems can also cause thinning and slow growth of baby\’s hair, such as immune system abnormalities, infectious diseases, autoimmune diseases, malabsorption of nutrients, etc. Thinning and slow hair growth in your baby can be a combination of many factors. Parents can keep their baby\’s hair healthy by paying attention to their baby\’s diet, sleep, and daily care, including chemical use, sun exposure, etc. If you are worried or think your baby is experiencing certain problems, please consult your pediatrician promptly for necessary examinations and diagnosis.
