This DIY dry shampoo is a homemade powder you apply to your roots to soak up oil and make hair look freshly washed again. The simplest default approach is to mix a plain starch base, apply it lightly with a makeup brush, wait 2 minutes, then brush or shake it out.
Basic DIY Dry Shampoo Recipe
1. Mix A Simple Base That Works For Most Hair
Use 4 tablespoons cornstarch or arrowroot powder as your starting base.
This is the “no-drama” version that is easiest to apply, easiest to adjust, and easiest to wash out later.
2. Add Tint Only If Your Hair Is Medium To Dark
For light brown hair, start with 1 teaspoon unsweetened cocoa powder mixed into your base.
If you are darker than that, you can add more cocoa in 1/4 teaspoon increments until it disappears at the roots.
3. Store It In A Dry, Easy-To-Use Container
Put your mix into a clean spice jar, shaker jar, or any small container with a tight lid.
If your bathroom gets steamy, store it in a drawer so the powder does not clump.
4. Apply With A Makeup Brush For The Most Natural Finish
Dip a fluffy makeup brush into the powder, tap off extra, and press it onto your roots along your part.
This keeps you from dumping too much in one spot, which is what usually causes a dusty look.
5. Use A Simple Timing Rule For Better Results
Let the powder sit for 2 minutes before you massage or brush it through.
That short wait gives it time to absorb oil so you need less product overall.
6. Blend It Out Without Flattening Your Hair
Massage lightly at the scalp, then brush through, or use your fingers to shake at the roots if you have curls.
If you accidentally used too much, a quick blast of cool air from a blow dryer helps lift extra powder fast.
Variations That Solve Common Problems
7. Make It Feel Lighter By Switching To Arrowroot
Use arrowroot powder instead of cornstarch if you hate a heavy or chalky feel at the roots.
This swap is also useful if cornstarch makes your scalp feel itchy or “coated.”
8. Boost Oil Control With A Small Amount Of Kaolin Clay
Add 1 teaspoon kaolin clay to your 4 tablespoons base if your roots get oily quickly.
Keep it light if your ends are dry, because clay can make the finish more matte than you want.
9. Add Odor Help With A Tiny Pinch Of Baking Soda
Add a very small pinch of baking soda if you need odor control after workouts.
Skip this entirely if your scalp is sensitive, because baking soda can be drying when used often.
10. Make A Softer Blend With Finely Ground Oat Flour
Replace 1 tablespoon of your base with finely ground oat flour if you want a softer, more calming feel.
Make sure it is powder-fine, because gritty oat bits can cling to hair and show near the hairline.
11. Make A Blonde-Friendly Version That Stays Bright
Stick with pure cornstarch or arrowroot, and apply in thin sections only at the roots.
If it looks too matte, use less next time and rely on the 2-minute wait to do more of the work.
12. Make A Light Brown Version That Does Not Look Muddy
Use 4 tablespoons base plus 1 teaspoon cocoa, then adjust slowly.
If it looks warm or orangey, reduce cocoa and consider a small pinch of plain base back in to lighten it.
13. Make A Dark Brown Version That Does Not Look Dusty
Use 4 tablespoons base plus 2 teaspoons cocoa for deeper brunette hair.
Test it in daylight after your first application, because indoor lighting can hide a slightly too-light mix.
14. Tint For Very Dark Hair With Activated Charcoal Carefully
Add a tiny pinch of activated charcoal to your dark brown mix if you have near-black hair.
Be extra careful with collars and pillowcases, because charcoal can transfer if you overapply or do not blend well.
15. Warm Up Auburn Tones With Cinnamon Cautiously
Add a tiny pinch of cinnamon if your hair has warm auburn tones and cocoa looks too cool.
Patch test first, because cinnamon can irritate some scalps even when diluted.
Extras That Make DIY Dry Shampoo Easier To Use
16. Use A Sectioning Pattern So You Apply Less Product
Part your hair in 3–5 quick lines across the crown and tap powder only where oil shows.
This makes your jar last longer and keeps your hair from feeling coated.
17. Fix The “Too Much Powder” Mistake With Cool Air
Use a blow dryer on cool for 10–15 seconds at the roots to lift extra powder.
This is the fastest way to remove the gray cast without re-washing your hair.
18. Make A Night-Before Routine For The Most Invisible Results
Apply a small amount before bed, then let it absorb overnight.
In the morning, you usually need only a quick shake at the roots and you are done.
19. Keep A Travel Mini For Emergencies
Pour a small amount into a mini jar so you can refresh bangs, your part, or your crown on the go.
A dedicated small brush stored with it is the upgrade that makes it actually usable outside your bathroom.
20. Add A Very Light Scent Only If Your Scalp Tolerates It
Add 1–2 drops of lavender or rosemary essential oil to the jar and shake well.
Avoid adding more than that, because too much oil can make the powder clump and feel greasy.
21. Use A Clean Brush Routine So It Never Smells Weird
Wash your application brush every 1–2 weeks if you use dry shampoo often.
A dirty brush can hold oil and old product, which defeats the whole point of refreshing your roots.
22. Set A Simple “How Often” Limit To Avoid Buildup
Try to cap DIY dry shampoo use at 1–2 days in a row before you do a real wash day.
If your scalp gets itchy or flaky, reduce how often you use it and apply less each time.
Key Takeaways
The basic DIY dry shampoo recipe is 4 tablespoons cornstarch or arrowroot powder, tinted only if needed.
Apply with a fluffy brush in thin sections for the most natural finish.
Let it sit for 2 minutes before you blend for better oil absorption.
Arrowroot feels lighter, and kaolin clay boosts oil control.
A cool blow dryer blast removes excess powder without rewashing.
Limit use to 1–2 days in a row to reduce buildup.
FAQ
Can you use flour instead of cornstarch or arrowroot?
Yes, but it is not ideal because it can feel heavier and look more visible at the roots. If you do use it, choose a very fine flour and apply less than you normally would.
Will DIY dry shampoo clog your scalp or cause dandruff?
It can if you apply too much or use it too many days in a row. Use a lighter hand, focus on roots only, and wash your hair regularly to prevent buildup.
How do you keep DIY dry shampoo from looking gray?
Apply less, wait 2 minutes before blending, and brush thoroughly. If you have darker hair, tint the mix with cocoa and adjust gradually.
Is DIY dry shampoo cheaper than store-bought?
Yes, it usually is because starch bases are inexpensive and last a long time. A single jar of base powder can make multiple batches for just a few dollars.
