Product Overview

Transform your hair styling routine with the Shark FlexStyle Air Styling And Drying System in Stone. This clever 2-in-1 device works as both a powerful hair dryer and versatile multi-styler for all hair types - straight, wavy, curly or coily. Just twist to switch between drying and styling modes. The system measures temperatures 1000 times per second, minimising heat damage while you style. With 4 heat settings, 3 airflow speeds and a cool shot, you'll have complete control. The Coanda Technology uses two air streams to attract hair and tame frizz for a smooth, glossy finish. Weighing just 0.66kg without attachments, it's comfortable to use, and the 2.8m cord gives you plenty of movement. The package includes a styling concentrator, oval brush, two 3.5cm auto-wrap curlers for different directions, and a soft storage bag. Powered by 1650 watts, it delivers fast drying and precise styling in one compact device. Model HD421SL comes with a 2 year manufacturer's warranty.

    Recommended hair styler

    Such a good hair styler.. even as a dryer, it dries the hair very fast. Its not very loud compared to my old hair dryer. I originally got it for the brush, and I’m so happy with it! I bought during end of financial year for a very affordable price as well. I would definitely recommend it!

    Very good all in one styler

    It’s a very good all in one styler that has replaced my existing tools. The hairdryer is compact and powerful. I have super long hair and drying them would take hours but I was surprised this powerful beast could dry it in less than 10mins. The power is controllable, can be a bit noisy but given the powerful airflow it delivers I am okay with it. I used curlers and oval brush too and they have been easy to style with. Definitely satisfied with the price and quality.

    Best overall styler

    I upgraded from Speedstyle to Flexstyle and I genuinely thinks this is the best overall styler/hairdryer. Love this for myself and my kids.

    All rounder hair styler for a fraction of price

    I loved this product, came in as a bundle at a fraction of big brand prices. The tools are very easy to use and style hair. I have used both the oval brush and curlers and my long hair looked great. If you get a hang of it, you can have well styled hair at home. This is coming very handy and has already replaced my multiple other styling tools. Much recommended.

    Love my Shark Flex

    I was in the market to buy a Dyson but the Shark instead as it was a fraction of the price. I am so pleased with my purchase as I believe the Shark is better than the Dyson. It is really strong and because i have thick, curly hair, it's difficult to find a tool that works for my hair. This is is. I have highly recommend everyone I know to buy it!

    Affordable Results

    I use my shark Flexstyle everyday. It’s easy to set up and very easy to use. The results are great both for straightening and curling. I love it and the price was budget friendly.

Q: Can the Shark FlexStyle dry hair and style it from damp, or does hair need to be fully dry first?

A: Yes. It is designed to take hair from towel-dried to styled, but the best results usually come when hair is mostly dry before using smoothing or curling attachments. Very wet hair takes longer and can reduce curl hold.

Q: How is the Shark FlexStyle different from a traditional hot air brush?

A: The main difference is versatility. FlexStyle works as a hair dryer and a multi-styler, using different attachments for drying, smoothing or curling, while a standard hot air brush is usually built for one styling approach only.

Q: Is the Shark FlexStyle a good option for fine or heat-sensitive hair?

A: Yes, it can be a better fit than very high-heat tools because it styles with fast airflow rather than hot plates. Fine or fragile hair can still over-dry, so lower heat and speed settings are usually the safer starting point.

Q: Does the Shark FlexStyle curl hair using airflow rather than a clamp barrel?

A: Yes. Its curling system uses airflow to wrap hair around the barrel, so it feels different from a traditional tong with a clamp. It generally works best on smaller sections that are about 80 to 90 per cent dry.

Q: Can the Shark FlexStyle replace a separate hair dryer and curling tool?

A: For many people, yes. It can cover everyday drying, smoothing and soft curls in one system, but it may not fully replace a high-heat iron if the goal is very tight curls or longer hold on thick, resistant hair.

Q: Do all Shark FlexStyle versions come with the same attachments?

A: No. FlexStyle bundles can vary, so the included attachments are not always identical across every pack or colour. Check the exact box contents listed on this page if a diffuser, brush or curling barrel matters to your routine.
