Low ferritin (under 70)
Hair will fall and refuse to regrow. Iron studies 'in range' can still leave ferritin too low for follicles.

Iron · Thyroid · Hormones
I'm losing my hair and my drive.
The brush gets harder to look at. The part is widening. Your ponytail is half the size it was. And underneath the visible loss, something quieter — the desire, the spark, the version of you who wanted things — has gone too. They aren't separate problems.
Hair loss in your 30s and 40s is usually iron, thyroid, hormone or cortisol — and usually four of them stacked. So is the lost libido. We test the same root causes for both, and they tend to come back together.
The Picture
If this is you,
it might sound like —
Read these the way you'd read a letter from someone who already knows. If three or more land hard, you're in the right place.
- Hair in the brush, the shower, the pillow.
- The part is widening — I can see scalp.
- My ponytail is half the diameter it was.
- Postpartum hair loss that never stopped.
- Brittle, won't grow past my shoulders.
- Libido that flatlined and didn't come back.
- I don't recognise the woman who used to want things.
- I'm not depressed exactly — I'm just empty.
+ Key Drivers
What's actually taking it.
Hair loss in this decade isn't usually one thing. It's iron, thyroid, hormones and cortisol stacked. Same drivers as the lost drive — same testing reveals both.
Subclinical hypothyroidism
Slows hair-cycle turnover. T3 is the active form. TSH alone misses it.
Androgen excess (or sensitivity)
Drives androgenic thinning at the part — common after the pill, with PCOS, after 40.
Low oestrogen + testosterone
The drive isn't in your head. It's your testosterone, oestrogen, DHEA. Often suppressed in your 30s/40s.
Cortisol depletion + adrenal fatigue pattern
Chronic stress depletes the substrates that make sex hormones. Drive disappears.
Postpartum cascade (1-2+ years out)
Iron + thyroid + B12 + hormones often unaddressed. Postpartum hair loss should not last past 12 months.
+ Key Tests
How we see the loss.
Hair and drive share root causes. Test once; address both. Most clients see drive return inside 4-8 weeks; visible hair regrowth at 3-6 months.

Comprehensive bloodsFull iron studies (ferritin target 70-100), full thyroid + antibodies, B12 (active), folate, vitamin D, zinc, fasting insulin.
-
DUTCH · Hormones + cortisolOestrogen, progesterone, testosterone, DHT, DHEA, cortisol curve. Drives the libido + androgenic hair-loss picture.
-
HTMA · Mineral panelMineral status — zinc, copper, magnesium, calcium. Hair literally is the test material.
-
OAT · Organic acidsMitochondrial energy production, B-vitamin status, gut dysbiosis. Background drivers of the whole picture.
+ Foundational Must-Haves
What you can start today.
Six daily moves. Drive often returns before hair does — hair takes 3-6 months to visibly regrow because of the cycle length.
- Iron-rich red meat 2-3x per week + vitamin C. Or supplement — but get ferritin to 70+.
- 30 g protein per meal. Hair, hormones, muscle. All of it needs protein. Most women under-eat it.
- Zinc 30 mg daily, with food. Hair, skin, immune, hormone production. Often quietly depleted.
- Cap caffeine + sugar — both deplete the substrates hormones are made from. Cortisol burns through them.
- Strength train twice a week. Increases testosterone, supports drive, builds the muscle that holds metabolism + mood.
- Sleep 8 hours minimum. Growth hormone (which heals follicles + drives libido) only releases in deep sleep.
+ The Process with How It Heals
Hair and drive come back together.
They have the same root causes — iron, thyroid, hormones, cortisol. Treat one and you almost always treat the other. Hair takes 3-6 months to visibly regrow. Drive often returns inside 4-8 weeks.
We test the full picture. Build a protocol from the data. Re-test at week 12 and 22 so you can see the change in numbers as well as in the mirror.
+ From the women in front of us
What changed.
Selected from clients who started here — visible hair loss, lost libido, postpartum cascade or 30s/40s decline — and worked through the 22-week reset.
My ferritin was 18. No one had ever told me. Three months in, the regrowth is everywhere.

I had given up on the libido thing — assumed it was just life now. It's not. My DHEA was on the floor.
