My 14-year-old daughter is selling her hair to raise money to buy a new horse. She has never dyed or treated her hair, she does not own a hairdryer or curling iron. Her hair is washed three times a week with well water and sulfite-free shampoo. It is shiny with a little bit of body and natural highlights. We eat an organic diet of farm-fresh meat and veggies. Regular professional trims.
