Cornstarch & Cornflour: DIY Dry Shampoo Recipes
Cornstarch and cornflour are the same ingredient — “cornflour” is the UK name, “cornstarch” the US one — and it’s a popular DIY dry shampoo because it absorbs oil at the roots. It works the same way commercial starch-based formulas do, minus the propellant and fragrance.
Simple recipes
| Hair color | Mix | Note |
|---|---|---|
| Light / blonde | 1 part cornstarch | Use alone or with a pinch of arrowroot |
| Brown | 2 parts cornstarch + 1 part unsweetened cocoa powder | Adjust cocoa to match your shade |
| Dark / black | 1 part cornstarch + 1 part cocoa powder | Test on a small area first |
How to apply
- Use a clean makeup brush or shaker to dab a small amount at the roots; part hair to reach the scalp.
- Wait a minute or two so the powder can absorb oil.
- Massage with fingertips and brush through thoroughly to remove visible powder.
Cautions: Fine powder is easy to inhale, so apply away from your face and avoid generous puffs. Cocoa powder can transfer to pillowcases, towels and light clothing. Stop if you notice itching, redness or flaking, which may mean the starch or any additives are irritating your scalp or building up.
Limits of DIY
Homemade mixes aren’t tested for stability or hygiene, so make small batches and keep them dry and covered. Like commercial products, they only absorb oil; they don’t clean. If you’re comparing them to ready-made options, see our dry shampoo and alternatives guide or the dark hair dry shampoo guide.
Frequently asked questions
Is cornstarch the same as cornflour?
Yes. Cornflour is the British term for cornstarch.
Does cornstarch dry shampoo work?
It can absorb surface oil at the roots and reduce greasy appearance temporarily. It won't remove dirt, sweat or product buildup.
Is DIY dry shampoo safe for my scalp?
For most people, occasionally. Avoid heavy use and wash when you notice itch, flaking or buildup. See a dermatologist for persistent symptoms.
What can I use instead of cocoa powder for dark hair?
Cocoa is the usual DIY tint. Commercial tinted formulas are another option; see our dark hair dry shampoo guide.
