This under-$70 hair straightener works just as well as the pricier T3

If you’ve ever stared at your credit card statement after buying a high-end hair tool and thought, “Well… at least my split ends look fabulous,” allow me to introduce a little budget-friendly plot twist.

Because while my beloved (and admittedly bougie) T3 straightener has long held court on my vanity, I recently stumbled upon a shockingly good under-$70 option that’s giving it a serious run for its money.

And yes, I’m just as surprised as you are.

Kristin Ess 3-in-One Professional Titanium Hair Straightener

Amazon

Let’s talk about the internet-famous Kristin Ess 3-in-One Professional Titanium Hair Straightener. It comes in at less than half the cost of most T3 straighteners, which feels like a small financial victory in a world where everything — from coffee to conditioner — has decided to become a luxury item.

But unlike some budget-friendly tools that feel like they might short-circuit mid-blowout, this one brings the quality.

The titanium plates are the real stars here. They heat up quickly (we’re talking minimal impatient pacing around your bathroom) and maintain a consistent temperature, which means fewer passes over each section of hair. Translation: less heat damage, more shine and significantly less time spent questioning your life in the mirror.

And true to its “3-in-one” name, it’s not just a straightener. The curved edges make it surprisingly easy to create loose waves or bends, making it extremely versatile.

Look, I’m not breaking up with my T3 entirely (we’ve been through too much!), but if you’re trying to stay under $100, this under-$70 straightener is the kind of find that makes you feel like you’ve beaten the system.

How long is Big Spring Sale?

Amazon’s Big Spring Sale is a marathon compared to the retailer’s shorter deal events. Shoppers can take advantage of seasonal discounts running from Wednesday, March 25 through Tuesday, March 31.

Do you have to be an Amazon Prime member to shop?

Unlike Prime Day in July, this event is open to everyone who shops on Amazon. However interested shoppers can grab a 30-day free trial to try Prime, and its many benefits with no strings attached, and gain access to exclusive deals, special “Prime” badges on select items and the added convenience of fast, free shipping.

What are the best deals?

From reporting on Amazon sales for years, we can tell you for certain that Big Spring Sale is the ideal period to stock up on household essentials, refill your skincare empties, save on the best vacuums to save your spring cleaning projects, and comb through the massive catalog of Amazon best-sellers.

Is it worth it?

We certainly think so! Big Spring Sale is a great chance to score deals on thousands of best-sellers, seasonal favorites, big-ticket tech and appliances and every day essentials. Our team diligently sorts through all the offers to find you the very best items to grab on sale.

When is the next Prime Day?

Already wondering when Amazon’s next Prime Day is? Prime Day takes place in July each year, so it’s safe to assume it will take place in mid-July 2026 — similar to previous years.
