Oh, those flourishing, healthy strands. All of us spend so much of time touching our hair, looking at it, taking care of it. We strive to choose the best shampoo, conditioner, hair oil. We wish for the best-looking tresses and resort to styling, coloring, blow-drying, perming and straightening. We assume the secret to long and lustrous hair is that fancy shampoo or the expensive salon treatment. Well darling, it is all about your diet.
