Testosterone for perimenopause: what TikTok gets wrong

What did @daniellenstanton actually say?

The creator made three core claims: that low testosterone itself can cause hair loss (not just testosterone therapy), that slow and steady dosing reduces side effects, and that consistent lab monitoring every three months is the right way to manage hormone replacement. These are all reasonable starting points, though some need more nuance than a short TikTok can offer.

She was replying to a question about hair loss and testosterone, which is one of the most common fears people bring to perimenopause conversations. Her framing, "low testosterone actually causes hair loss," is the most medically interesting claim here, and it deserves a proper look rather than a quick dismissal.

Does the science back this up?

Partially, yes. The relationship between testosterone and hair loss is genuinely bidirectional, and that part is accurate. But the mechanism is more complicated than the video implies, and anyone making decisions based on this clip should know the full picture.

The hair loss most people associate with testosterone therapy is androgenetic alopecia, driven by dihydrotestosterone (DHT), a metabolite of testosterone. Higher testosterone levels can mean more substrate for DHT conversion via the 5-alpha reductase enzyme. That is the conventional concern.

But the creator is right that hypogonadism, meaning clinically low testosterone, is also associated with hair changes. A 2018 review by Trüeb in the International Journal of Trichology noted that testosterone receptors are present in hair follicles, and that both deficiency and excess can disrupt the hair growth cycle. Low testosterone in women has been linked to diffuse hair thinning, particularly in postmenopausal and perimenopausal populations. So saying low testosterone "causes" hair loss is not wrong, but it oversimplifies a dose-response relationship that depends heavily on individual genetics, DHT sensitivity, and baseline hormone levels.

What did they get wrong (or right)?

She got the bidirectional nature of testosterone and hair loss basically right, which is more than most TikTok creators manage on this topic. The advice to "stay slow and steady" with dosing is also consistent with clinical guidance, though framing it as purely a side-effect-avoidance strategy undersells the real reason: it allows for accurate dose titration and reduces the risk of supraphysiologic levels, which carry their own consequences including, ironically, accelerated hair loss.

Where the video falls short is that it does not mention DHT at all. Anyone watching this who has a genetic predisposition to androgenetic alopecia needs to know that even modest testosterone increases can accelerate hair loss through DHT conversion, regardless of how careful their dosing is. A 2020 study by Glaser and Dimitrakakis in Maturitas found that testosterone pellet therapy in women significantly increased DHT levels, and that hair loss was among the most commonly reported adverse effects in sensitive individuals. Omitting this is not dangerous misinformation, but it is an incomplete picture.

Her point about lab monitoring every three months is solid. That is consistent with Endocrine Society clinical practice guidelines for women on testosterone therapy.

What should you actually know?

If you are in perimenopause and experiencing hair loss, testosterone is one variable on a long list that includes thyroid function, ferritin levels, estrogen, prolactin, and autoimmune conditions. Assuming it is low testosterone without labs is a mistake.

If you are considering testosterone therapy and worried about hair, the honest answer is that risk depends on your genetics and your DHT conversion rate. Testing baseline DHT before starting therapy gives you and your doctor something to compare against. Some providers add a 5-alpha reductase inhibitor for patients who show DHT elevation after starting testosterone, though that comes with its own considerations.

The creator's emphasis on finding a doctor who will engage with your questions and run labs consistently is genuinely good advice. A 2021 survey published in Menopause by Faubion and colleagues found that a significant proportion of women report their symptoms being dismissed by providers, and that care quality improves meaningfully when patients have access to a knowledgeable, communicative clinician. That part of the video is worth taking seriously.

• Hair loss on testosterone therapy is not inevitable, but it is also not just a dosing problem.
• DHT, not testosterone directly, is typically the driver of scalp hair loss in genetically susceptible individuals.
• Low testosterone can cause diffuse hair thinning, but so can thyroid disorders, iron deficiency, and estrogen changes common in perimenopause.
• Quarterly lab monitoring is consistent with Endocrine Society recommendations for women on testosterone therapy.
