21 Best Prime Day Beauty Deals of 2026 (We Sifted Through Hundreds to Pick Them)
Beauty deals are among the few Amazon Prime Day sales that are great nearly across the board. Whereas some tech products are only on sale because they're old, or the deals are the same you can find year-round, the beauty deals we've spotted are almost always on new and trendy products or classics we wouldn't want to go without. We do test a lot of tech professionally, but we apply that same testing protocol to the beauty products we use in our everyday lives. Here are some deals on our tried-and-tested favorites.
Make sure to check our list of the Absolute Best Prime Day deals for more verified discounts on the gear we recommend.
Updated 10 am ET Thursday, June 25: We've added new deals from BaByliss, Conair, Revlon, and Tymo.
This is the best budget hair straightener I have ever tested, performing as well on my 3a curly hair as flat irons five times the price. This Prime Day deal is not the most dramatic discount, but you won’t find a better straightener for under 30 bucks. The 1-inch plates heat up to 410 degrees Fahrenheit in just 34 seconds, smoothing even the most recalcitrant frizz and leaving hair shiny and healthy-looking. —Kat Merck
The outer surface of this reliable, high-quality iron heats up as well, so you can use it as a curler.
Our favorite budget blow dryer, this Conair is not fancy, but it'll get the job done.
I love this lightweight, user-friendly diffuser and reach for it multiple times per week. It's especially good for curly hair. It isn't the fastest diffuser I've ever used, but it's gentle on my tresses and lets me dry them without feeling guilty. Goodness knows I put my hair through the wringer already, but I don't feel like I'm adding to the damage when I use this on wash days. —Louryn Strampe
This viral heated straightening brush is a hit every Prime Day. It won’t replace a straightening iron, and it did nothing for Kat's hair, but former WIRED reviewer Brenda Stolyar swore by it.
WIRED reviewer Nena Farrell gave this a solid 8/10 when she reviewed it last year, finding that it beat many of its pricier competitors in terms of performance.
What's better than an excellent blow-dry brush? Three blow-dry brushes in one! This set gets you Drybar's acclaimed Double Shot brush head (Nena's favorite), along with the paddle brush Smooth Shot (Boutayna's favorite) and smaller, easily maneuverable Half Shot for shorter styles or bangs. The Double Shot brush by itself usually costs more than this, so you're practically getting two extra brushes for free with this deal. —Kat Merck
