Research-based comparison. Exact-model and kit documentation. No drying-time, sound, handling, curl or hair-damage tests; manufacturer performance marketing is not a head-to-head result. Sources checked 2026-09-08.
Quick Verdict
Consider Shark HD542 if its folding design and styling tools cover your routine at a lower price. Pay more for Dyson HD07 only when its particular attachments are useful to you.
- You want a folding dryer and an attached smoothing brush Shark SpeedStyle Pro Flex
- You specifically want the Dyson attachment selection Dyson Supersonic

Compare the tools you will actually use
Choose the attachment set for the way you style your hair, then compare the complete-kit prices. Shark’s folding handle can be useful when storage is tight. The Dyson kit may be worth more to you if you specifically want its Gentle air attachment or wide-tooth comb. Neither brand name nor the total number of attachments establishes better results.
Match the dryer and the box contents
This is the original Dyson HD07 listing, not Nural or r. It lists five attachments, but the HD07 manual warns that some accessories may not be included in every package. Shark’s US HD542 page lists four styling tools. Recheck the retailer variant instead of carrying those contents over to every color, region or bundle.
For curls, both kits start with a diffuser
The earlier page assigned Dyson the curly-hair win from its accessory count. That skipped the question of which diffuser works for your routine. We have no matched styling test to answer it. If you only diffuse, the unused smoothing tools should carry little weight in your budget; if you switch styles, list the tools you need and compare the cost of the complete set.
For smooth styles and storage
Shark’s QuickSmooth Brush combines brushing and airflow in one attachment; decide whether that is how you want to style. Its folding handle is a documented storage difference. Dyson offers a different tool set. We have not measured frizz reduction, finish quality or time saved, so these are workflow choices rather than performance rankings.
What a price premium does not prove
We removed the claims that more watts ensure faster drying, that an isolated noise figure proves quieter operation, and that either dryer is the better option for damaged hair. If speed, noise, fatigue or hair results justify the extra cost for you, those questions still need comparable testing. Check seller, condition, regional voltage and returns before buying.

Who Should Buy Which
Shark SpeedStyle Pro Flex HD542
The HD542 kit includes a QuickSmooth Brush and folds for storage. If those features fit your routine and the full kit is cheaper, there is a practical reason to choose it. Higher wattage is not evidence it will dry your hair faster.
Dyson Supersonic HD07 Hair Dryer
The linked HD07 kit lists Gentle air and a wide-tooth comb alongside its other tools. Consider it when those are tools you expect to use. Check the actual box contents; some Supersonic kits include fewer attachments.
Frequently Asked Questions
Which is better for curly hair?
Both selected kits include a diffuser. We have not compared curl definition, frizz or drying time, so there is no tested curl winner here. Compare the diffuser and other tools you will use, then check the full kit price and return terms.
Does Shark’s higher wattage mean it dries faster?
No. Electrical power consumption alone cannot establish drying time on your hair. Our previous page incorrectly used wattage to declare Shark faster. A useful speed comparison needs the same hair, starting moisture, technique and finish criterion.
Is this the Dyson Supersonic Nural or Supersonic r?
Neither. This page covers the original HD07 listing. Nural and r are different products; do not assume a feature or accessory shown on those pages belongs to the linked HD07.
Which dryer is quieter or easier to hold?
We do not have comparable noise measurements or a handling test. The earlier 77 dBA recommendation and calculated weight advantage were not adequately supported and have been removed. A single number measured under unknown conditions does not settle either question.

Buying checks and offers
Before choosing a bundle
- Confirm original Dyson HD07 or US Shark HD542. Supersonic Nural, Supersonic r and other SpeedStyle versions are different products.
- Check the exact diffuser, smoothing brush, comb and other accessories in the selected offer. Compare the cost of the kit you need.
- Check voltage on the selected unit before travel or import. A folding handle does not establish dual-voltage compatibility.
- Confirm new/refurbished condition, seller, warranty eligibility and return terms. We do not maintain live prices.
