Most of us have tried a DIY haircut at some point—often with mixed results. That’s the problem Tony Litwinowicz wanted to solve. HairFin is his answer: a plastic measuring tool that makes giving yourself a trim a whole lot less scary. It’s simple, precise, and doesn’t try to do too much.
At the time Tony invented HairFin, he wasn’t some big-name stylist or tech guru. He was just an engineer and a dad who wanted an easier way to cut hair at home. The idea started with trying to give decent haircuts to his own kids.
Shark Tank Appearance: An Offbeat Pitch That Worked
When HairFin showed up on Shark Tank in Season 13, Tony walked in asking for $25,000 in exchange for 20% of the company. That valued the business at about $125,000. The pitch was a little awkward and didn’t exactly set the stage on fire—most of the Sharks were confused by the product and its target market.
To be fair, home haircutting tools aren’t exactly flashy, and HairFin didn’t pretend to be revolutionary. Some Sharks wondered if the consumer base would be too small, or if professional barbers would bother with it at all. Tony rolled with all the questions, demonstrating how HairFin guides scissors to create straight, even haircuts without a complicated process.
Most of the Sharks bowed out. But toward the end, Daymond John saw something he liked. Maybe it was the tool’s everyday practicality, or maybe it was Tony’s genuine, straightforward style. Either way, Daymond offered $25,000, but he wanted 30% of the company.
Tony accepted. And with that, HairFin secured one of the smallest deals on the show that season—but also one of the more memorable ones for its niche appeal and how much it reflected the heart of the homegrown inventor.
Closing the Deal and the First Wave of Success
People always wonder: Did the Shark Tank deal actually go through after filming ended? In HairFin’s case, things moved quietly at first. For a while, there were no public updates, and fans weren’t sure if Daymond and Tony closed their agreement.
Then, about a year later, it became clear that Daymond and Tony both followed through. Not only did Daymond invest, but by July 2024, he’d earned back five times what he put in. That’s a nice payday for a small investment, and a sign that HairFin’s business was stronger than it looked on TV.
The real proof came in the numbers. In the first year after Shark Tank aired, HairFin racked up $600,000 in sales. That’s a lot of haircuts, especially for a product most people didn’t know existed until Tony was on the show.
By summer 2024, HairFin had crossed the $1 million mark in lifetime sales. For a no-batteries-required plastic tool, that’s nothing to sneeze at.
Expanding the HairFin Line and Finding New Fans Online
Originally, HairFin was one size: a simple comb-like guide for making one length of cut. But soon after Shark Tank, Tony acted on feedback and added more options. Now, HairFin comes in sizes from one inch to six inches, letting you pick the length you want—even for layered looks.
People can buy HairFin on the company’s own site, but also on larger online marketplaces. You’ll find it on Etsy, Walmart, and Amazon. That made it easier for people doing their own haircuts—or cutting a child’s hair in the kitchen—to stumble across the product where they shop anyway.
A big part of the company’s appeal comes from where HairFin is made. Tony has stuck with manufacturing in the USA—a detail that gets a lot of support from buyers, especially families and barbers who like to keep things local.
The Business Gets Real: Performance and Reputation in 2025
Shark Tank can create a brief burst of buzz, but most products fade away after that spike. Not HairFin. As of 2025, the business is still shipping orders, updating its tools, and keeping up website sales.
The brand has picked up plenty of positive reviews online. Customers say HairFin is simple to use—even for people who’ve never cut hair before. Some folks use it to give themselves pixie cuts. Others stick with trimming bangs or keeping a kid’s hair neat between trips to the barber.
Tony’s approach is no-nonsense. The tools don’t come loaded with fancy extras, and they’re not meant to replace a pro stylist. Instead, people like that HairFin slots into real family routines. You want a quick haircut before school picture day? Or do you just need a trim without the hassle? That’s where this tool shines.
Word-of-mouth and the visibility from Shark Tank both helped. Searches for HairFin surged for months after the episode. The company’s social media accounts filled with videos and satisfied customer photos, and the reviews reflected real-world success rather than overnight hype.
The Money: Net Worth, Growth Rate, and Where Things Stand
By early 2025, HairFin’s estimated net worth was around $213,000. That’s factoring in sales, manufacturing costs, a growing online retail presence, and annual growth averaging 10%. For something born from a parent’s frustration with home haircuts, those numbers show a steady pace—not a runaway viral hit, but a decent business.
Daymond John’s investment turned out to be a smart move. Earning back five times his original stake is a solid result, especially when the upfront risk looked so high. Most people tuning into Shark Tank probably wouldn’t have guessed this product would outlast some flashier pitches from that same episode.
If we step back and look at the bigger picture, HairFin has found a place in the do-it-yourself haircare market. While it’s definitely a niche—I mean, not every household is going to cut hair at home—it serves the folks who do, and it makes their lives easier.
HairFin has managed to keep its product affordable and accessible, competing with gadgets that cost way more and promise results they seldom deliver. Right now, it has a corner of the DIY space—not huge, but loyal.

Looking Back—and Ahead—at HairFin’s Journey
So what’s the takeaway with HairFin? Tony came to Shark Tank pitching something basic: a tool for ordinary people who want more control over cutting hair at home. His pitch didn’t immediately wow the Sharks, but his persistence (and a product that actually works) gave him staying power.
Getting Daymond on board provided more than just a bit of cash. It gave HairFin a shot at online retail deals, ongoing advice, and nationwide visibility. The brand’s simple focus—do one thing well—never changed, and customers noticed.
The fact that it’s still in business in 2025, with good customer feedback, steady online sales, and clear signals of continued growth is impressive for something that started as a parent’s kitchen solution. HairFin isn’t trying to take over haircare or disrupt anything. It’s simply stuck with making a decent tool for a specific kind of shopper.
Looking forward, HairFin’s not suddenly going to show up in every salon, but it probably doesn’t need to. As long as people out there are looking for a better way to trim hair at home—whether to save a few dollars, avoid a trip to the barber, or just have more control—a straightforward product like this has a job to do.
Tony Litwinowicz and Daymond John have built a small but sturdy partnership. HairFin keeps improving, slowly expanding, and carving out a corner in a crowded market. Not every Shark Tank deal leads to a headline-grabbing empire. Sometimes, it’s about finding a simple idea that works, connecting with customers who care, and staying in it for the long haul.
