The idea for Cyriac Lefort’s new startup, MyHairAI, came to him two years ago. The French native was sitting in a New York hair salon for a routine haircut when his hairdresser looked at him and said he was starting to lose a bit of hair. Lefort, who is 32, recalls that the hairdresser did not say this to his friend sitting next to him. In his mind, he was not balding, and he still does not think he is. But he noted that when someone tells you you are losing your hair, you buy whatever they suggest. He bought the shampoo the hairdresser recommended and left thinking that anyone could sell a man anything by telling him he is losing his hair. He said hair loss is such an emotional topic for men and women.
That interaction led him to research the hair loss industry, where he discovered a confusing landscape filled with misinformation and clinics with unverified reviews. He later went to a hair doctor who told him he was, in fact, not balding. This experience inspired him to create a product that uses AI to help men diagnose hair loss.
Lefort is a serial entrepreneur who has exited one company and is currently running two others with his partner, Tilen Babnik, who is 28. The duo decided to team up and build a third company called MyHair AI. They vibe coded the product in just a few weeks. It works by having users take photos of their heads and upload them to the MyHair app. The AI technology then analyzes those photos to measure hair density and detect early signs of hair loss.
Over time, as a user uploads more photos, the AI tracks the evolution of their hair loss. This allows people to build personalized hair loss protection routines. Users can also find specialists or discover clinics through the platform and read verified reviews to avoid being scammed.
Lefort explained that their AI tells you what is really happening with your hair, matches you with products that make sense for your hair type, and explains the science behind them, including possible side effects. He believes that by bringing transparency and medical accuracy to this fifty billion dollar market, they can completely reorganize how people understand, treat, and shop for hair health.
It took about a year of ideation, a few weeks of vibe coding on Cursor, a few months of scientific and clinical validation, and a few more weeks of building a consumer app for the duo to be ready to launch MyHair AI. The company launched this summer. Lefort said they did not hire anyone for the initial prototype, as it was fully vibe coded. Now that the product has grown, their engineers handle the code to ensure it is solid and scalable. MyHair AI is an example of how fast startups can build these days with the rise of vibe coding prototypes.
Lefort said the product already has more than one thousand paying subscribers and two hundred thousand user accounts. The app has analyzed more than three hundred thousand scalp photos. The company has partnerships that allow specialists and clinics to access the MyHair AI so they can evaluate their own patients faster. The company recently announced that Dr. Tess, a renowned dermatologist, is joining its board.
Other companies in the market notably include Hims. Lefort said MyHair is different because the product is one of the few that has built a dedicated AI model, trained on more than three hundred thousand hair images, to diagnose baldness, rather than using a more generic large language model.
Lefort said the company is now focused on expansion. It aims to build a booking platform and partner with more clinics. He hopes to build AI that works in the real world. He stated that men worry about two main things in their health, sexual dysfunction and hair loss, and that MyHair AI addresses one of the biggest day-to-day concerns.
