A Hair Dryer for Sensitive Scalps

If you have a sensitive scalp like me, the Shark SpeedStyle Pro Flex is worth the investment. Shark’s Scalp Shield feature monitors heat 1,000 times a second to ensure it never exceeds 230 degrees Fahrenheit. It comes with four versatile attachments à la Dyson, and it's surprisingly light (1.57 pounds). Plus, it folds up for easy travel or storage. I’ve tested the Dyson Airwrap, and this gets you there for way less cash.

A Budget Blow-Dry Brush

We’ve tested a lot of blow-dry brushes, but the Revlon One-Step Volumizer Plus (8/10, WIRED Recommends) wins on value. It dries and styles at once, with a slimmer, 2-inch oval barrel that's detachable and easier to handle than the original. The ceramic titanium tourmaline coating cuts down on heat damage, and four settings (plus a cool shot) give you all the control you need. At $46 (down from $70), it's a steal.

A Water Flosser

I'm a devout flosser, and while this Waterpik isn't a replacement for string floss, it's a killer addition to my dental care routine. The rotating nozzle and three pressure settings blast gunk from places threads can't reach. One fill gives you 45 seconds of powerful spray, which is all I need. It's compact, waterproof, and cordless. It charges fast in just four hours and comes with a travel bag and tip case. Ideal for tight counters and travel. My gums have never been happier.

A Sonic Toothbrush

I've tested a lot of sonic electric toothbrushes, but I keep circling back to the Philips Sonicare 4100. It's gentler on gums than oscillating brushes, dead simple to use, and packed with features that matter. You get a pressure sensor, a two-minute timer, two intensity modes, and a two-week battery life. It even reminds you when it's time to change the brush head. At $40 for Prime Day (down from $50), it's the one I'd grab.

A Beard Trimmer

This is one of the most versatile beard trimmers thanks to the dozen or so attachments in the box. They're easy to swap, but you can also use the trimmer without the guard for the closest shave, and it doesn't nick or pull. You can use it plugged or unplugged (we rarely had to plug it in), and it's completely waterproof.
