If you have flat hair, you needn’t spend a fortune on products looking for the perfect volumising shampoo or styling product. Dry shampoo will work wonders, and you can get it for just a few pounds. It needn’t be used just to clean up greasy roots, it works wonderfully as a styling product for fine flat hair. Simply tie your hair back into a ponytail and lightly mist the dry shampoo over the head and crown, so that you get the roots. Untie the ponytail and brush through. Voila! Bouncy, voluminous tresses.
