Perimenopause, hair, weight — finally heard, finally treated.
Your doctor told you your labs were “normal.” Our physicians run the labs that actually matter for women — and build protocols that restore sleep, energy, libido, and body composition.
Start women's protocolBuilt for your biology.
Perimenopause Protocol
Comprehensive hormone panel + bioidentical estradiol, progesterone, and DHEA. Addresses hot flashes, sleep disruption, mood swings, and weight gain at the root — not with band-aids.
Hair + Skin Restoration
Targeted DHT management, GHK-Cu peptide, biotin complex, and thyroid optimization. Addresses the 3 most common root causes of female hair thinning: hormones, thyroid, and nutrient deficiency.
Body Composition
Metabolic optimization through thyroid, DHEA, and peptide support. Not a crash diet — a physiological reset that addresses why your body holds onto weight despite your efforts.
Thyroid + Energy
Full thyroid panel (not just TSH) — free T3, free T4, reverse T3, TPO antibodies. Most women with 'normal' TSH have suboptimal T3 conversion. We catch it, we fix it.

Women's health FAQ.
When should I start hormone therapy?
There's no single 'right' age. Many women benefit from bioidentical hormone optimization in their late 30s to early 40s — during perimenopause — when symptoms first appear. The key is lab-driven timing: we measure your hormones, not your birthday, to determine when intervention makes sense.
Is bioidentical HRT safe?
Bioidentical hormones — molecularly identical to what your body produces — have a different risk profile than synthetic alternatives used in older studies. When prescribed by a board-certified physician, monitored with regular labs, and dosed appropriately, bioidentical HRT has a well-established safety profile. KAYU monitors you at every step.
Can you help with hair thinning?
Yes. Female hair loss is almost always multi-factorial: thyroid dysfunction, estrogen decline, DHT sensitivity, iron deficiency, or cortisol dysregulation. We run labs for ALL potential root causes and build a protocol that addresses each one — not just minoxidil and hope.
What about weight gain during perimenopause?
Perimenopausal weight gain is driven by declining estrogen, rising cortisol, and shifting insulin sensitivity — not by eating too much. KAYU addresses the metabolic root causes with bioidentical hormones, thyroid optimization, and when appropriate, metabolic peptides. We fix the physiology so your efforts actually work again.
