It takes a baby at least a week to grow eyebrows. Of course, different babies have different physical conditions, so the time for the baby's eyebrows to grow is not fixed. If you accidentally hurt the growth part of your baby's eyebrows when trimming your baby's eyebrows, it may also affect the growth of your eyebrows, leading to changes in the growth position and shape of your eyebrows, or even ugly? The eyebrows are upside down, and it is best not to shave the baby's eyebrows.
It is wrong to say that the baby will get thicker when shaving his eyebrows, and there is no scientific basis. The thickness of baby's eyebrows is mainly influenced by genetic factors. Generally, mom and dad's eyebrows are thick, but the baby's eyebrows are thick. If mom and dad's eyebrows are not thick, the baby's eyebrows are not thick.
Parents should be careful not to trim their baby's eyebrows casually, because the eyebrows will automatically fall off when the baby is three to six months old. This is a normal metabolism, and then new eyebrows will slowly grow.
