Our Personal Wax Warmer Guarantee awaits.

Waxing magic happens every day at our Flatiron studio. Picture this: when you walk through our doors, you’re greeted by our staff, who has your wax prepared for you and you alone. It’s our Personal Wax Warmer Guarantee! Your waxing experience is all about you, with your very own personalized wax warmer ready to roll. No sharing, no double-dipping, just pure pampering perfection. We take cleanliness and hygiene very seriously because we care about you.

Uni K Natural Wax Flatiron’s natural waxing tops all other methods of hair removal

Sure, waxing removes hair. But did you know it also leaves your skin absolutely silky smooth? You get a long-lasting exfoliation too! For no extra cost! That’s why waxing is so popular, and natural waxing in particular. Shaving simply cuts the hair, and then the next day, it’s back. The battle rages on every day. Messy, chemical-filled creams aren’t any better, and they’re certainly not good for your skin or your health. Do you really want your skin absorbing those chemicals? Instead, wax with Uni K’s pine resin-based natural wax; there are no chemicals like in other waxes, and the hair is gone for weeks. It’s a healthy choice. Be consistent, and you’ll see your hair grow finer and slower. Get that glow practically maintenance-free. Keep your skin healthy when you wax naturally at Flatiron Uni K. It’s a natural choice.

Some hair removal processes can really stress your beauty budget, but not at Uni K. If you’re a first-timer, you’ll love this. At Uni K Natural Wax Studio Flatiron, you get 50% off your very first service. We really want you to experience the natural wax difference, so we’re making this incredible offer. The thing is, once you try us, you’ll want to come again and again. It’s just smart to choose a natural process, right? And there’s no other wax that is more effective at removing hair more comfortably. You’ll be pleasantly surprised.

Once you fall in love with us, and we’re sure you will, don’t pay full price to maintain your silky smooth skin.

Join the K Club and get as many bikini waxes as you want all month long. That means you can come in for touch-ups anytime. Did we mention our natural wax allows for touch-ups? Other waxes don’t.

Buy a K Pack—our packages of 6 or 10 of the same waxing service—and use them whenever you like. The best part is that K Packs include free waxes that save you money. Here’s another idea.

Uni K is your beauty ally, so that means we take care of you! One more thing: maintain and nourish your skin every day with our line of natural skin care K Beauty. You’re going to love that too.

Men, a whole new level of grooming awaits you at Uni K Natural Wax Flat Iron!

Thanks to our unrivaled natural wax and expert waxers, you’ll experience long-lasting results and reduced regrowth with every session. Yes, you can have that youthful groomed look that is always in style.

Our wax is as natural as can be, free from harmful plastics found in waxes elsewhere. With our natural and proprietary pine resin-based wax, which is also gluten and paraben-free, your skin is treated to a gentle and effective hair removal session, leaving you feeling super smooth, super happy, healthy, and hair-free! Concerned about sensitive skin? Rest easy! That same natural wax ensures a comfortable experience, free from irritation. Say so long to the shaving struggle and stubborn stubble. Swing by Uni K Natural Wax in Flatiron and let the grooming begin!

Refer your friends, and you both get rewarded.

If you are super happy with the Brazilian, bikini, leg, back, chest, underarm, leg, or other hair removal service you just had (and we will make sure you are), tell your friends. When they come in for a service, they’ll get a big discount, and you’ll get $15 in your account. It’s our way of welcoming newcomers to our natural waxing and thanking fabulous folks like you who share the love!
