My 3-year-old daughter has had a beautiful head of blonde hair. In the last 3 months her hair color has brightened and thinned significantly. It’s not thinning in patches, but there is definitely less of it all over. She is otherwise healthy and takes multi-vitamins regularly. Do you have any idea what the problem may be?
Hair character does change. We see such changes from ‘baby’ hair in the newborn, to hair in the child, to teenagers, to adulthood, to older age. I would suspect if she is healthy, that she is just experiencing a change in hair thickness. It is not unusual for blonde children to see changes. My children started off blonde (my three boys) and ended brown. My oldest had fine, platinum blonde hair as a young child and now he has coarse, brown hair.
