Quick Answer
Apply to roots only, hold the can 25–30cm away, let sit 1–2 minutes, massage firmly into the scalp, then brush through. Pro tip: apply the night before — it absorbs oil while you sleep for a freshly-washed look by morning.
How to Use Dry Shampoo — Step by Step
1
Apply to completely dry hair only
Dry shampoo does not work on damp or wet hair. The alcohol base cannot function and you end up with a chalky paste. Hair must be fully dry.
2
Section hair and spray only the roots
Part your hair into sections to expose the scalp. Shake the can well. Hold it 25–30cm from your head — much further than you think. Spray in short bursts directly at the oily roots. Do not spray the lengths — it will dry them out.
3
Wait 1–2 minutes
This is the step most people skip. Give the product time to absorb the oil. Rushing this is why white residue appears — the product has not had time to absorb properly.
4
Massage into the scalp with fingertips
Rub the product firmly into the roots with your fingertips. This distributes it evenly, aids absorption and breaks down any white residue.
5
Brush through
Brush from roots through to ends to remove any excess product. Hair should look and feel refreshed.
Apply the night before for best resultsApply before bed, massage in briefly, then sleep on it. The product absorbs oil all night and by morning your hair looks genuinely freshly washed. This is a complete game-changer.
Choosing the Right Formula for Your Hair Colour
Light or blonde hair: Standard white spray formulas blend invisibly
Dark brown or black hair: Use a formula specifically for dark hair — standard white formulas leave an obvious grey-white cast on dark roots
All colours: Invisible or translucent spray formulas work on all hair colours
Do not rely on it exclusivelyDry shampoo does not actually clean hair — it absorbs oil and adds volume. Using it daily for extended periods causes scalp buildup that can clog follicles. Wash hair at least every 3–4 days even with regular dry shampoo use.
Frequently Asked Questions
Three causes: holding the can too close, not waiting long enough before massaging in, or using a white formula on dark hair. Hold 25–30cm away, wait 2 minutes, massage firmly and brush. Switch to a tinted or invisible formula for dark hair.
Using it every day long-term causes scalp buildup. Use it 2–3 days between washes as a guide. If you wash infrequently and rely on it daily, gradually extend time between washes slowly — your scalp adjusts and produces less oil over 4–6 weeks.
