If you're looking for an affordable dry shampoo, Tresemmé has come out with an both an aerosol and foam product which are supposed to help refresh your hair, without the need for washing. The aerosol is for oily/normal to straight hair and the foam is for dry/wavy to curly hair. I recently bought and tried the aerosol. The can is of a pretty good size and it will probably last me a while before I repurchase.

I used the dry shampoo after the second day I washed my hair. It was looking limp and a little oily at the roots. After spraying this product, My hair doubled in volume and I noticed that it did not leave a white, powdery residue. It's scent is very fresh, like most of the Tresemmé products. It also got rid of the oily look and made my hair look so much better! To get the best results, shake vigorously and spray in short bursts over the oily areas. Do not spray like a hair spray all over your head. Keep shaking the can after every spray. I let it sit in my hair for about a minute and then brush through it and shake my hair up with my fingers.

I definitely recommend this product! It's cheap ($3.99 CAD) and will probably go on sale often and it delivers good results.
