Cutting your own hair at home is tricky. Many people struggle to get an even length, especially around the back and sides. Without professional tools, DIY haircuts often end up uneven or messy. This frustration led Tony Litwinowicz to invent the HairFin, a simple yet clever tool designed to help people achieve salon-quality haircuts at home.
The HairFin is a small, hand-held measuring guide that attaches to clippers. It ensures each stroke cuts hair to the exact same length, eliminating guesswork. No more uneven patches or awkward self-barbering angles. Tony created this product after his own failed attempts at cutting his hair. He wanted a foolproof solution for anyone who prefers trimming their hair at home.
In Shark Tank Season 13, Tony pitched HairFin, asking for $25,000 in exchange for 20% equity. He shared that the product had already made $41,000 in sales through Amazon. While most Sharks weren’t convinced, Daymond John saw potential and struck a deal.
HairFin Net Worth Shark Tank Update 2025
Tony was looking for an investment of $25k in exchange for 20% equity in the company. At the time of the episode, he valued his company at $125k. Tony successfully secured a deal with Daymond for an investment of $25k for 30% equity in the company. The investment adjusted the company’s net worth to around $83k. After the show was aired, the company saw a big increase in website traffic, sales, and social media exposure. As per my rough estimate, the current net worth of HairFin is around $600k.

Tony Litwinowicz Backstory + Their Initial Pitch
Tony Litwinowicz is an engineer with 11 patents to his name. His background in product design helped him create the HairFin. The idea came from personal experience. As a kid, his mom cut his hair. As an adult, he struggled to do it himself.
After several botched haircuts, Tony decided to invent a solution. He designed the HairFin—a small, lightweight tool that clips onto hair clippers. It acts as a measuring guide, ensuring every cut is the same length. The tool is especially useful for fading and trimming the back of the head, where mistakes are common.
Before appearing on Shark Tank, Tony had already launched HairFin on Amazon. Sales were decent, reaching $41,000. However, he needed funding and expertise to scale the business. His pitch asked for $25,000 for 20% equity, hoping a Shark could help with manufacturing, marketing, and retail expansion.
Tony’s demonstration impressed the Sharks with its simplicity. He showed how the tool could help anyone, even beginners, cut their hair evenly. Despite the strong pitch, most Sharks hesitated due to the product’s niche market.
Queries + Shark’s Responses, and Final Deal
Robert Herjavec was the first investor to exit the conversation. He believed that the market for a product called HairFin was too small and that while it had some usefulness, it didn’t represent a significant business opportunity.
Mark Cuban also decided not to invest. He liked the HairFin product but thought it wouldn’t grow into a large business.
Lori Greiner, who specializes in gadgets for the home, turned down the opportunity because she felt HairFin didn’t match her typical product line.
Kevin O’Leary appreciated the engineering behind the product but didn’t see how it could grow into a bigger business, so he also chose to pass on the investment.
The only investor still interested was Daymond John. He had previously invested in a similar grooming item called Scrub Daddy and recognized potential in HairFin. Daymond made an initial offer of $25,000 for 40% ownership of the company. However, the creator, Tony, thought that was too much of a stake to give away and countered with $28,000 for 25% ownership.
Daymond declined that offer, but after some negotiation, they reached an agreement of $25,000 for 30% equity. Tony accepted this deal, gaining Daymond as a partner, which could help his business grow.
Product Availability
After being featured on Shark Tank, HairFin, a product designed to help people trim their hair at home, became more widely available. You can now buy HairFin from their official website, Amazon, Etsy and Walmart.
Tony, the creator, has also introduced new sizes for HairFin, ranging from 1 inch to 6 inches. This means there are different options available to suit various hairstyles and trimming needs. The kits are priced between $14.99 and $29.99, depending on which one you choose.
Customers have been giving positive feedback about HairFin, particularly praising how easy it is to use. Many reviews mention that it helps people achieve the right haircuts, like even trims and fades, without needing to go to a salon.
What Happened To The HairFin After Shark Tank?
As of today, HairFin, a company offering a hair-cutting tool, is still operating successfully. HairFin is selling its products on well-known online stores like Amazon, Walmart, and Etsy, which helps it reach many customers. Many users are pleased with HairFin, with some saying it has significantly improved their DIY haircut experience, labeling it a “game-changer.”
Although HairFin hasn’t expanded into brick-and-mortar retail stores, involvement from Daymond (likely a well-known business figure or investor) could lead to changes in that area.
Tony, who seems to be one of the co-founders or key figures in the company, is actively working on product improvements using his engineering background. While sales growth hasn’t been extraordinary, HairFin has a dedicated group of fans who continue to support the brand.
HairFin is maintaining a steady presence in the market, supported by customer satisfaction and potential future growth opportunities.
Conclusion
HairFin entered Shark Tank Season 13 as a clever solution for DIY haircuts. Though most Sharks doubted its potential, Daymond John invested $25,000 for 30% equity.
Since the show, HairFin has expanded its product line and availability. While it hasn’t become a household name, it remains a useful tool for at-home barbers.
With Daymond’s support, HairFin could grow further. For now, it’s a solid option for anyone tired of uneven self-haircuts.
