Hair loss is more common than anyone admits, and rapid weight loss on a GLP-1 can bring it on. We're building a program that matches treatment to your pattern, not a one-size kit, and we'll be upfront that much of this care is off-label.

It's called telogen effluvium, and the fix is often treating the cause, not just a pill.
Rapid weight loss (including on a GLP-1) can stress the hair cycle and deplete iron, zinc, and vitamin D, triggering a shed a few months in. It usually reverses. Our plan starts by treating the cause and supporting regrowth, not defaulting you to a lifelong prescription.
IronThyroidProteinPace of lossTelogen effluvium happens when a stressor (rapid weight loss, illness, childbirth, or a nutrient drop) prematurely pushes many growing (anagen) follicles into the resting (telogen) phase at once. About 2–4 months later those hairs shed together, which is why the loss looks sudden and diffuse. Because the follicles aren't destroyed, hair usually regrows once the trigger resolves, so we focus on the cause (iron, thyroid, nutrition, pace) and give it time.

Matched to your pattern. Receding/crown, diffuse thinning, or post–weight-loss shedding are treated differently.
Minoxidil, topical or oral. The foundation for most people. Your provider picks the form that fits.
For men: DHT-blockers where appropriate (finasteride, escalating to dutasteride), with honest side-effect counseling.
For women: minoxidil, and spironolactone where it fits. Hormone-free, pregnancy-safe paths when needed.
Treat the cause first. If fast weight loss set off the shed, we check iron, thyroid, and nutrition before reaching for a lifelong prescription.

We're describing the program we're building, not a promise of results. Most hair-loss medication is used off-label, and your provider will tell you what the evidence does and doesn't support.
Generic finasteride runs about $11 at a low-cost pharmacy (vs ~$70 usual cash price). What membership buys is the relationship: refills handled, questions answered, a provider who follows your progress with you.
Minoxidil is over-the-counter. You don't need us for it; the row is here so you can see nothing's marked up. More options (like oral minoxidil and, for women, spironolactone) at launch.
In the semaglutide (Wegovy) trials, hair loss was reported in about 3% of people vs ~1% on placebo, rising to roughly 5% in those losing more than 20% of their body weight, and reviewers attribute it to the rapid weight loss itself, not the drug. Fast loss can shift many follicles into the resting/shedding phase and deplete iron, zinc, and vitamin D. It's usually reversible: support nutrition, check thyroid and iron, ease the pace, and give it time; minoxidil can help regrowth.
Source: GLP-1 & hair loss systematic review (NIH/PMC) →Source: Wegovy label summary →Hair grows in cycles: a multi-year growth phase (anagen), a brief transition, then a resting/shedding phase (telogen). In pattern loss, DHT shortens anagen, so hairs grow thinner and shed sooner. Finasteride shifts more follicles back into anagen (a 48-week trial showed increased total and anagen hair counts), with noticeable results around 3–4 months and fuller results near a year. Minoxidil often causes a brief "dread shed" in the first 2–8 weeks before regrowth at 3, 6, and 12 months.

In the pivotal trials, sexual side effects were uncommon and only modestly above placebo (decreased libido ~1.8% vs 1.3%). In 2025, however, the EMA confirmed suicidal ideation as a side effect (frequency unknown), and the FDA warned about compounded topical finasteride after reports of mood and sexual effects, some persisting after stopping (the debated "post-finasteride syndrome"). That's why our protocol is to screen, consent, and stop-and-reassess, and to make hormone-free options easy.
