If you are a dry shampoo user you know it can help on those days you are too lazy or lack time to shampoo. To get better results when you need them, apply your dry shampoo product to your hair’s roots immediately after shampooing and blow drying. By using dry shampoo on just-washed hair, the product is able to absorb the oils as soon as your scalp releases them. This will minimize grease and prevents the build-up that weighs down your hair. You’ll have that fresh, just-washed look longer.
