Estrogen and hair: what dropping hormones do to your hair cycle

Short answer: Estrogen helps keep hair in its long growing phase. When estrogen falls in perimenopause and menopause, the growth phase shortens, more hairs sit in rest, and the balance tips toward androgens, so strands come in finer. The result is thinner-looking hair on top and a wider parting line. Crowned by Her Part gives you fuller, thicker-looking hair with the Fingertip Trick.

Does low estrogen make your hair thin?

Yes. Estrogen keeps hair in its long growing phase. When it drops in menopause, each hair grows for less time and comes in finer. You see it on top and along your parting line. Crowned by Her Part gives you fuller, thicker-looking hair with the Fingertip Trick each morning.

How your hair cycle works

Every hair grows for years (anagen), rests for two to three months (telogen), then falls and makes way for a new one (Paus and Cotsarelis, 1999). The longer the growing phase, the longer and thicker your hair looks overall.

What estrogen does for hair

The hair follicle is a direct target of estrogen, and it carries estrogen receptors (Ohnemus et al., Endocrine Reviews, 2006). That's why hair often looks its thickest in pregnancy, when estrogen is high, and sheds after birth, when it drops.

What changes when estrogen drops

A shorter growing phase

With less estrogen, hairs spend less time growing and more time resting. More strands in rest means less hair on your head at any moment.

Androgens take the lead

Testosterone doesn't rise in menopause, but with estrogen falling, the balance shifts toward it. In sensitive follicles on top of the head, that means finer, shorter hairs. That's why so many women see hair thinning at the crown first.

Drier scalp and hair

Hormonal changes in midlife show up as drier, less glossy, more fragile hair, a pattern dermatologist Paradi Mirmirani described as a midlife "hair crisis" (British Journal of Dermatology, 2011).

Where you'll see it

• A wider parting line
• More scalp at the crown
• A thinner ponytail
• Hair that won't hold volume or gloss
• More hairs in your brush

What helps hair look fuller through menopause

Talk to your doctor about hormones

Hormone therapy is a medical decision for you and your doctor. Bring it up at your next menopause checkup.

Feed your hair

Protein at every meal, iron-rich foods, and a check of iron and thyroid levels with your doctor.

Be gentle

Loose styles, low heat, a soft brush, and a moisturizing conditioner on the lengths.

Daily scalp care

Crowned by Her Part gives you fuller, thicker-looking hair. A few drops along your parting line and crown every morning, the Fingertip Trick, and you style as usual.

Crowned by Her Part is made with five peptides (analogs of aFGF, bFGF, IGF-1 and VEGF, plus a CCL2-family conditioning peptide), arginine, saw palmetto, Scutellaria root, rosemary, eucalyptus, soybean germ and wheat germ extracts, and vitamin E.

What the ingredient research shows:

• Rosemary: in a randomized trial of 100 men with thinning hair, rosemary oil performed on par with 2% minoxidil, with both groups showing higher hair counts at six months and less scalp itching in the rosemary group (Panahi et al., Skinmed, 2015).
• Saw palmetto: 50 men using topical saw palmetto products had higher average and terminal hair counts at 12 and 24 weeks (Wessagowit et al., Australasian Journal of Dermatology, 2016).
• Growth-factor peptides: topical FGF-1 and FGF-2 brought on the hair growth phase earlier and kept it going longer in mouse studies (Lin et al., BioMed Research International, 2015).
• Eucalyptus: ongoing use in a scalp lotion improved measured gloss and bounce (Mamada et al., Journal of Cosmetic Science, 2008).

Crowned puts all of them in one leave-on serum for fuller, thicker-looking hair.

What you'll notice with Crowned, and when

Hair works on a slow cycle: each strand grows for years, rests for two to three months, then makes way for the next (Paus and Cotsarelis, New England Journal of Medicine, 1999). Crowned is built for that cycle, so the changes stack up in a clear order.

• From the first days: a light serum that sinks into your scalp, no residue, and a Fingertip Trick you'll actually look forward to.
• In the first weeks: hair that feels softer, with more gloss and bounce. Eucalyptus extract in a scalp lotion improved measured gloss and bounce of hair with ongoing use (Mamada et al., Journal of Cosmetic Science, 2008).
• Over the first two months: more lift at the root and hair that looks thicker where it grows from.
• Months three to six: fuller-looking coverage where you used to see scalp, a ponytail with weight in it, and photos that look like you again. That's the window the ingredient studies measured: topical saw palmetto at 12 and 24 weeks, rosemary oil at six months.

Take a photo of the top of your head on day one and every two weeks after. Daily use is what builds the result, and the photos show it.

Frequently asked questions

Does low estrogen cause hair thinning?

Falling estrogen shortens the hair's growth phase and shifts the balance toward androgens, so hair comes in finer and looks thinner on top.

Why did my hair get thicker in pregnancy and thinner in menopause?

High estrogen in pregnancy keeps more hairs growing. In menopause, estrogen falls and more hairs move into rest.

Does hormone therapy help hair?

Ask your doctor. It's a medical decision that depends on your health history.

Can hair look thicker after menopause?

Yes. A lift-focused cut, gentle styling and daily scalp care with Crowned by Her Part give you fuller, thicker-looking hair.

How long until I notice a difference with Crowned?

Softer, glossier hair in the first weeks, more lift at the root over two months, and fuller-looking coverage in months three to six.
