We recently sat down with Dr. Ivan Cohen, physician at the Center for Hair Transplantation, to talk about why the decisions men make about hair loss in their 30s often determine how many options they have later. Dr. Cohen practices at Connecticut's most experienced hair restoration practice, with more than 30 years in business and 10,000+ procedures performed, and the first practice in New England to offer robotic follicular unit extraction (FUE) with the ARTAS® System.
At Thesis, we think a lot about how people take a proactive approach to their own biology. That might mean sharpening focus with a personalized nootropic, or catching a health change early, before it becomes a bigger decision. We wanted to hear how Dr. Cohen sees that same mindset play out with hair loss.
Q: A lot of men notice thinning or a receding hairline in their 30s but don't do anything about it right away. What keeps them from acting sooner?
A: Mostly the assumption that they're an outlier, or that looking into it means something is seriously wrong. Neither is true. By age 35, a large share of men have noticeable thinning, and that number climbs by 50. If you're seeing changes in your 30s, you're closer to the norm than the exception. The men who wait usually just don't know there's already a clear next step available to them, not that they're scared of the answer.
Q: When someone does look into it, what's the biggest mistake you see?
A: The biggest mistake is guessing at the cause. A confirmed diagnosis always comes first. Thinning hair can come from genetics, hormonal changes, stress, thyroid conditions, or certain medications, and each of those points to a different treatment. Someone who diagnoses themselves off a forum thread often ends up treating the wrong problem for months before seeing a specialist. A proper evaluation from a board-certified dermatologist or hair restoration specialist always comes first.
Q: Once someone has a real diagnosis, why is timing still so important?
A: Because a lot of what we can offer works best on hair that's still thinning, before it's gone for good. Medical therapies like finasteride and minoxidil are most effective early. If you wait five or ten years to see if it gets worse, you usually lose follicles you could have preserved. On the procedural side, robotic and minimally invasive FUE techniques have also changed what's possible: the scarring, downtime, and unnatural results people picture from older hair transplants are largely outdated. But none of that changes the basic math that earlier action means more options later.
Q: Thesis's audience tends to already be proactive about their health and cognitive performance. What would you tell someone with that mindset about applying it here?
A: Treat it like anything else you're already optimizing. The men who handle hair loss best monitor it the same way they'd track any other long-term health metric, with something like an annual check-in in their 30s, well before they're deciding whether it's become a problem worth solving. Set expectations early too: results from treatment or a procedure typically take several months, sometimes closer to a year to fully show. Men often stop too soon simply because they expected a faster payoff, even when the plan is working.
Q: If someone reading this is on the fence, what's the one thing you'd tell them to do this week?
A: Get evaluated. That's it. No commitment to treatment required yet. Hair loss is rarely urgent, but it is time-sensitive, and a single consultation is what turns a vague worry into an actual plan with actual options.
