What is the reason for the child's thin and yellow hair at the age of two?

Patient's question:

No discomfort, it's always been this way

Doctor's answer:

Just had the barber use the razor to shave it twice during a haircut, and then I stopped paying special attention to it. Now that I've grown up, I'm a handsome young man with thick, black hair. Surprisingly, my hair is even thicker and darker than that of other kids the same age.
Advice: Regarding your child's nutrition, we focus more on dietary supplements, such as feeding him pig ribs, large bone soup, seafood like shellfish, chicken soup, eggs, and milk. We rarely give him commercial nutritional supplements from pharmacies. I hope this information can be helpful to you. Wishing your baby healthy and happy growth!
