The all over same color of dyed hair looks so dyed! A super stylist showed me how to have natural looking dyed hair. If going darker, choose an ash shade of the color you want. Forget dark brown to black hair color, it never turns out natural. Streak the color on your hair and with a plastic brush, brush the color through your hair. Never saturate your hair with the dye like shampoo. Your hair should have many different shades of your hair color to look natural. It's easy to do and you don't need much color. In fact you'll throw away more then half the bottle if your hair is short. Don't be tempted to use it all just because you bought it.
