My teenage daughter has been using this organic leave-in hair treatment full of vitamins on her hair the past month. She is a runner with a long, wavy ponytail. We live in Florida and her hair gets tons of sun exposure because she runs after school every day.
I have watched her hair improve while using this product. She sprays it in while her hair is damp less than 1 hour after washing her hair. Then she lets her hair airdry all night. In the morning her waves are bouncier and fuller than they have been since she started running. (Which means since she started washing her hair every single night after running in sun almost every single day.)
