There is no such thing as the shaver baby hair is the better.
The rate of growth and the quality of the hair depends on the hair follicles. Shaving the hair cannot affect the follicles, so it cannot affect the quality of the hair.
There are many factors affecting baby hair, including external factors, such as hair growth environment is relatively poor, such as air pollution, air dryness, etc.; internal factors: including genetic factors, their own nutritional intake, etc. will also affect the quality of hair, as well as whether there is a scalp disease, etc.; human factors: such as frequent shampooing, poor-quality shampoo and so on will affect the quality of hair.
If infants need to improve the quality of hair, not by shaving more, but to eat a balanced diet, reasonable diet; at the same time to strengthen the scalp care.
