How to Use Dry Shampoo Correctly (No White Cast, More Volume, Longer Between Washes)
Spray dry shampoo on dry hair, at the roots only, holding the can about 6 to 8 inches away and working in small sections. Leave it for a minute or two so it absorbs oil, then massage with your fingertips and brush through. It works best applied the night before, and it never replaces washing.
“Most people use dry shampoo as an emergency spray when their hair already looks flat. Use it before the oil wins, the night before or the morning after a wash, and it keeps a blowout looking fresh for another day without the gray haze.”Her take
How dry shampoo works
Dry shampoo is a fine powder, usually a starch or clay, that soaks up oil at the roots so hair looks cleaner and has more lift. It doesn't remove oil or clean the scalp; it hides oil until your next wash.
It comes as aerosol sprays, non-aerosol sprays and loose powders. Sprays are easiest to spread evenly. Powders give more control for small areas like the hairline and part, and are handy if you dislike the feel of aerosols.
Step by step: how to apply it
Do this on completely dry hair, with clips, ties and pins out.
- Shake the can well.
- Part your hair into sections about 1 to 2 inches apart, starting at the part and the crown, where oil shows first.
- Hold the can 6 to 8 inches from your head and spray in short bursts directly at the roots, not the lengths.
- Do the hairline and the area behind the ears, which get oily quickly.
- Wait one to two minutes so the powder can absorb oil.
- Massage the roots with your fingertips, then brush through from roots to ends.
- Finish with a cool shot of a hair dryer for extra lift, if you like.
The night-before trick
Dry shampoo works best on hair that isn't oily yet. Apply it lightly at the roots the night before you'd normally wash. Your scalp's oil mixes with it overnight, and by morning it's invisible and the roots have lift.
This works especially well on the second night after a blowout. Sleep with your hair loosely gathered on top of your head in a soft scrunchie, then shake it out in the morning.
How to avoid the white cast
White residue nearly always comes from spraying too close or using too much. Hold the can farther away than you think, spray less, and give it time to absorb before you brush.
If you have dark hair, a tinted dry shampoo for brown or dark hair helps, and so does brushing with a boar or mixed-bristle brush, which spreads the powder out. If you do see a cast, a blast of warm air from a dryer and a firm brushing usually removes it.
How often can you use dry shampoo?
Use it for a day or two between washes, not as a replacement for washing. Powder builds up at the roots if you use it day after day, and that buildup can leave hair dull and the scalp feeling itchy or heavy.
When you do wash, shampoo the scalp thoroughly, and wash twice if you've used a lot of dry shampoo. If your hair feels coated even after washing, a clarifying shampoo every so often helps remove buildup.
Using dry shampoo for volume and styling
Dry shampoo is also a texturizer. A light spray on clean roots gives grip for updos, half-up styles and ponytails, so pins and claw clips hold better.
For a sleek ponytail on second-day hair, spray the roots, brush everything back, and then smooth the surface with a little cream. To revive flat roots under a hat, spray, flip your head upside down and massage.
Questions people ask
Can I use dry shampoo on wet hair?
No. It needs dry hair to absorb oil. On wet hair it clumps and leaves a paste.
Should I spray dry shampoo on the lengths of my hair?
Not for oil, which sits at the roots. A tiny amount on the mid-lengths can add texture for styling, but most of it belongs at the scalp.
How long should I leave dry shampoo in before brushing?
One to two minutes is usually enough. Applied the night before, it's ready by morning.
Why does my hair look worse after dry shampoo?
Usually too much product or too little blending. Use less, spray from farther away, wait, then massage and brush thoroughly.
The takeaway
Dry hair, roots only, 6 to 8 inches away, wait, massage, brush, ideally the night before, and a proper wash after a day or two.
