What did @alisonlumbatis actually say?
She said hair loss is a common side effect of testosterone therapy, and her solution is taking an androgen blocker daily. Specifically, her doctor prescribes spironolactone, which she credits with giving her "thicker" hair, reducing chin hair, and clearing her skin. That is a reasonable summary of how this combination is sometimes managed in clinical practice, and she is not making up the mechanism.
To be precise about what she claimed: androgens are the cause of the hair loss, spironolactone blocks those androgens, and the result is less hair shedding plus cosmetic side benefits. She is speaking from personal experience, not citing studies, which matters for how seriously we should weigh her conclusions.
Does the science back this up?
Mostly, yes, but with important caveats. Exogenous testosterone in women can elevate dihydrotestosterone (DHT), which binds to androgen receptors in scalp follicles and triggers androgenetic alopecia. That mechanism is well established. Spironolactone does block androgen receptors and inhibit 5-alpha reductase activity to some degree, which is why it has been used off-label for female pattern hair loss for decades.
A 2020 systematic review by Layton et al. in the Journal of the American Academy of Dermatology found spironolactone effective for female pattern hair loss in multiple retrospective and prospective studies, though high-quality randomized controlled trial data remain limited. A 2019 RCT by Sinclair et al. in the British Journal of Dermatology showed meaningful hair density improvement in women taking 200mg daily. The anti-androgen effect on sebaceous glands, which she mentions for skin clarity, is also supported by evidence from acne trials dating back decades.
So the basic science she is invoking is real. The gaps are in the nuance she skips over.
What did they get wrong (or right)?
She got the mechanism right. Testosterone-related hair loss in women is androgen-mediated, and spironolactone is a legitimate off-label tool for managing it. Credit where it is due: recommending an androgen blocker rather than just stopping testosterone entirely is a more nuanced approach than most TikTok hormone content offers.
What she glosses over matters, though. First, she frames androgens as simply the cause of hair loss, but the reality is more dose-dependent and individual. Some women on testosterone therapy never experience significant hair loss. Genetics, baseline androgen sensitivity, and testosterone levels all play a role.
Second, she presents her personal result, "my hair is now thicker than it's been in a long time," as if it generalizes. Spironolactone can slow or halt hair loss in many women, but regrowing lost hair is harder and less predictable. Framing thicker hair as the expected outcome is optimistic at best.
Third, she does not mention that spironolactone carries its own side effect profile, including electrolyte disturbances, menstrual irregularities, and potential drug interactions. Women with kidney disease or taking ACE inhibitors face real risks. That omission in a 74,000-view video is a problem.
What should you actually know?
If you are on testosterone therapy and noticing hair shedding, that is a real and recognized side effect, not something you imagined. The androgen receptor pathway is a legitimate target for managing it. Spironolactone is not fringe medicine here. It appears in the Endocrine Society guidelines and is commonly used by dermatologists for androgenetic alopecia in women.
But the conversation should happen with a physician who can assess your baseline potassium, kidney function, and full medication list before starting it. This is not a supplement you add without evaluation.
The other option, which she does not mention, is reducing the testosterone dose. Hair loss often correlates with supraphysiologic testosterone levels. A telehealth provider managing your hormones should be tracking levels and adjusting before adding more medications to compensate for side effects from the first one.
- Spironolactone doses used in hair loss studies typically range from 100 to 200mg daily. Do not self-prescribe a dose based on a TikTok video.
- The benefit for hair loss can take 6 to 12 months to become visible. Quick results are not typical.
- If you are on potassium-sparing diuretics, NSAIDs, or have any kidney condition, spironolactone requires careful medical supervision.
