Don’t Spray too close to your scalp.
To evenly distribute your hair and avoid getting a chalky white look, spritz the dry shampoo about 10 inches away from your roots.
Don’t use too much product.
When your hair is greasy, a good dose of dry shampoo can make it look fresher, but apply too much and your hair can will dull and discolored. As with all products, it’s easier to add more later than remove excess, so use a little dry shampoo, then wait a few minutes, and add more if you feel like your hair is still too greasy.
Don’t apply it to the wrong part of your hair.
Don’t spray dry shampoo all over your head — just stick to the top couple inches. Chances are that the bottom of your hair isn’t greasy, so applying an oil absorber all over can just make your hair stiff and lackluster.
Use Your Fingers
If you don’t, the dry shampoo just sits on top of your hair and isn’t able to do its job. So use your fingertips to massage it into your roots and scalp.
Wait… Let it Work
Don’t just spray and go — give the product a chance to work into your hair and really absorb the oil at your roots by letting it sit for a couple minutes before you massage it in and brush or comb it through.
Don’t Rely on it every day.
As somebody who shampoos a couple of times a week at most, I always use dry shampoo between washes and it works great at keeping my oiliness at bay. But doing this too often can actually be detrimental because the built-up residue can eventually clog your follicles. So try to do it only once between hair washes so your scalp has a chance to breathe.
