My daughter has healthy Virgin hair. It's blonde and mostly straight, however in high humidity it will curl right up into ringlets. Since she's 8 she's obviously never smoked, drank or taken drugs. She eats very healthy. She rarely wears her hair up. We don't blow dry it use products or curling or flat irons on it. It's washed 3 times per week with natural shampoo.
She is wanting to cut off 10 inches. Her hair is about 3 inches thick.
