A man in his late thirties walked into the Columbus clinic last month holding a photograph of himself at twenty-five. He pointed to the temples and the crown — the two areas where his hair had visibly thinned over the past four years — and asked the same question I get from a few patients every week: is this hormones, and if so, what do I do about it. He had already tried over-the-counter minoxidil, two different DHT-blocking shampoos, biotin, collagen peptides, and a saw palmetto supplement his neighbor recommended. None of it had moved the needle. He was about to spend several thousand dollars on a hair transplant consultation, and he wanted to know whether there was anything to address upstream first.
The answer to his question is the same answer I give most men in his position. Yes, the hair loss is hormonal in mechanism. No, the answer is not as simple as blocking DHT. And the workup that determines what to actually do has very little to do with the hair itself and almost everything to do with what is happening in the rest of his endocrine system.
What DHT actually is and what it does to a hair follicle
Dihydrotestosterone is a metabolite of testosterone. The conversion happens through an enzyme called 5-alpha reductase, which sits in several tissues — prostate, skin, scalp, and the sebaceous glands attached to hair follicles. DHT is roughly three to five times more potent than testosterone at binding the androgen receptor. In tissues that need a strong androgen signal, that potency is useful. In a genetically susceptible scalp follicle, it is the mechanism that drives miniaturization.
Miniaturization is the actual problem in androgenetic alopecia. The follicle does not die in the early stages — it shrinks. Each successive growth cycle produces a thinner, shorter, less pigmented hair, until the follicle eventually produces only vellus hair (the fine, colorless hair you can barely see) and then stops producing at all. The terminal hair you started with becomes a vellus hair becomes nothing, over a span of years. The pattern follows a recognizable distribution — temples and crown in men — because those follicles carry the highest density of androgen receptors and the highest local 5-alpha reductase activity.
What people often miss is that the systemic testosterone level has very little to do with this. I have evaluated men with total testosterone in the low 200s ng/dL who are losing hair aggressively, and men with optimized levels above 800 ng/dL who have full heads of hair into their sixties. The variable is not how much testosterone is circulating — it is how much DHT is being produced locally at the follicle and how sensitive that follicle's receptors are. That is genetic. You cannot change the receptor sensitivity. You can change what is happening to the signal.
Why the conventional approach disappoints so many men
When I evaluate someone for hair loss, I find that most men have already tried the consumer-grade interventions — minoxidil, biotin, saw palmetto, the various scalp serums — and arrived frustrated that nothing worked. There is a reason for that, and it is worth being honest about.
Topical minoxidil is a vasodilator that extends the anagen (growth) phase. It works for some men, partially, and only as long as you keep using it. It does not address DHT. Saw palmetto is a weak 5-alpha reductase inhibitor with inconsistent clinical evidence — it is not in the same league as a prescription DHT blocker, and treating it as such sets up a predictable disappointment. Biotin does almost nothing for androgenetic hair loss; it helps if you are deficient, and most patients are not. The DHT-blocking shampoos that get marketed aggressively have minimal contact time with the follicle and almost no penetration to the dermal papilla where it matters.
The interventions that actually move the needle on androgenetic alopecia are the ones that interrupt the DHT signal at a meaningful level — finasteride or dutasteride orally, which inhibit 5-alpha reductase systemically; topical finasteride, which inhibits it locally with a lower side-effect profile; and PRP or growth-factor-based scalp treatments that can improve follicle function and partially reverse miniaturization in early-stage patients. These are the levers that produce measurable change. None of them are stocked at the drugstore.
The hormone picture I look for in the workup
In my practice, the labs I order before recommending any DHT-related intervention go beyond a hair-loss panel because the rest of the endocrine system tells me what kind of patient I am dealing with. The comprehensive lab work I run includes total and free testosterone, SHBG, estradiol, DHEA-S, prolactin, a full thyroid panel (TSH, free T3, free T4, reverse T3, antibodies), fasting insulin, HbA1c, ferritin, vitamin D, and a complete metabolic panel.
Not sure where to start?
The Start Here pathway walks you through the most common entry points and helps you decide which consultation type is the right fit. Five minutes of self-assessment can save you a wrong-direction conversation.
A few patterns show up repeatedly. The first is the man whose total testosterone is normal but whose SHBG is high and whose free testosterone is at the bottom of the range. He is functionally low-T at the tissue level even though his lab report does not flag him. His hair loss is one symptom; his low energy, low libido, and central weight gain are the others. Treating the hair without treating the underlying picture leaves him symptomatic in three other domains.
The second is the man with elevated insulin and a triglyceride-to-HDL ratio above two. Insulin resistance suppresses SHBG, raises free testosterone available for conversion to DHT, and accelerates the miniaturization process. His hair loss is a downstream consequence of metabolic dysfunction, and addressing the metabolic problem improves the hair outcome more than blocking DHT alone.
The third is the man with low ferritin (below 70 ng/mL is a meaningful threshold for hair) or untreated subclinical hypothyroidism. Both produce diffuse shedding that overlays the androgenetic pattern, and patients often blame DHT for what is actually a nutritional or thyroid problem. Treating the wrong mechanism wastes years.
The fourth is the man whose labs are unremarkable and whose hair loss is genuinely a pure androgenetic process. For him, the conversation is simpler — but he still benefits from understanding the rest of his metabolic and hormonal picture, because the same physiology that drives hair loss at thirty-eight tends to drive cardiovascular and metabolic problems at fifty-five.
How I evaluate candidacy and what treatment looks like
When I sit down with a patient at the lab review, I am sorting candidacy across a few axes. How early in the process are we — Norwood scale 2, Norwood 4, or further? The earlier the intervention, the better the response. Is the patient willing to commit to a daily medication for the long term, knowing that the benefit ends if the medication stops? Is there a personal or family history that affects whether oral finasteride is the right starting point, or whether topical formulations make more sense? What is happening with the rest of his hormone picture, and does that picture argue for men's testosterone replacement in parallel — not because TRT helps hair (it does not directly), but because the same patient often has other deficits that warrant attention?
For a man in his thirties or forties with early-pattern loss, intact follicles, and no contraindications, the protocol I lean toward is oral finasteride 1 mg daily, often combined with topical minoxidil and a structured PRP series. I will sometimes substitute topical finasteride if the patient is concerned about systemic side effects or has a libido picture that would not tolerate further androgen suppression. For a man whose workup also reveals low-T physiology, hormone optimization (or specifically the men's protocol) becomes part of the same plan, with the understanding that we monitor DHT closely because raising testosterone raises substrate available for conversion. A Biote pellet therapy approach in that scenario sometimes includes anastrozole to manage estradiol, and the dosing is adjusted with hair loss in mind.
For DE|RIVE Hair Restoration, the in-clinic regenerative protocol I use includes PRP scalp injections on a structured schedule, often paired with exosome therapy or growth-factor concentrate depending on the patient's response curve. The mechanism is different from medication — instead of blocking the DHT signal, it stimulates the follicle environment to support fuller growth cycles. The two approaches work well together and address different parts of the same problem.
What to expect and the timeline I set with patients
I am direct with patients about timeline because unrealistic expectations are the most common reason men quit a working protocol before it has a chance to demonstrate results. Hair grows about half an inch a month. The hair you can see today reflects what was happening in your scalp three to six months ago. If we start an effective protocol today, the first signal that something is changing — reduced shedding in the shower, slower progression at the temples — usually shows up around three to four months. Visible thickening on photographs takes six to nine months. Full benefit at twelve to eighteen months.
The other thing I tell patients honestly: you will get worse before you get better in some cases. Finasteride can cause a brief shedding phase in the first few months as miniaturized follicles cycle out and replace with stronger hairs. PRP can produce a similar early shedding pattern. This is expected and is not a reason to stop. The patients who do best are the ones who understand the timeline going in and stay the course through the awkward window.
If your hair loss is something you have been weighing — and especially if you have already tried the over-the-counter route without success — the next step I would recommend is a structured hormone consultation with the lab panel I described above. Bring photographs from five and ten years ago if you have them. Bring any recent lab work. We will sit down with the data, talk through the mechanism that is driving your specific pattern, and build a protocol that targets that mechanism rather than a generic one. You can book at the Columbus location or the Warner Robins location — same protocol, same lab partners, same approach.
