Hair Shedding After 40
If you've noticed more hair in the shower drain or on your brush in your 40s, you're far from alone. Most of the time it's a mix of normal shedding, hormone shifts and stress, and much of it settles. Here's how to tell what you're seeing.
How much shedding is normal?
Losing roughly 50 to 100 hairs a day is typical, according to the American Academy of Dermatology. Long hair makes the same number look like more, and you'll often see a bigger clump on wash days because hairs that loosened earlier come out together.
Why shedding often picks up after 40
- Perimenopause. As estrogen levels start to swing and fall, more hairs can leave their growth phase early. Many women notice it first at the crown or along the part.
- Stress and big life events. A high-stress stretch, surgery, illness, a high fever or losing a lot of weight can trigger a wave of shedding called telogen effluvium.
- Nutrition gaps. Low iron stores and restrictive diets are common in midlife and are worth checking with a blood test.
- Thyroid changes. An under- or overactive thyroid becomes more common with age and can cause diffuse thinning.
Why it shows up months later
Hair grows in long cycles. A trigger today usually shows up as shedding two to three months from now, which is why it can feel like it came out of nowhere. Read more on why shedding shows up months later.
Shedding or thinning?
Shedding is hair falling out from the root; the ponytail may feel thinner but the part usually looks the same. Thinning that slowly widens your part or shows more scalp at the crown can point to female pattern hair loss, which is worth getting checked early. See thinning at your part.
What you can do
- Track it: take a photo of your part in the same light once a month.
- Ask your doctor about blood work, including ferritin (iron stores), thyroid and vitamin D.
- Be gentle: skip tight ponytails and very hot tools while shedding is heavy.
- Eat enough protein and don't crash diet.
- Support your hair from the inside. Firmora Women's Daily Supplement is two capsules a day of vitamins, minerals and botanicals made for women's hair through hormonal change. Give any approach at least 90 days, because that's one hair cycle.
When to see a doctor
See a doctor or dermatologist if shedding lasts more than six months, comes with patches or scalp pain, or your part is clearly widening. The AAD notes that treatment tends to work best when started early.
Questions women ask
Is it normal to lose more hair in your 40s?
Some increase is common, especially through perimenopause, but heavy shedding that lasts more than a few months is worth discussing with a doctor.
Will hair grow back after shedding?
With telogen effluvium, the AAD says hair often regains its usual fullness within 6 to 9 months once the trigger has passed.
Which supplement should I take?
It depends on what's behind your shedding. Start with blood work, then take the 60-second hair quiz to see which Firmora plan fits.
