Hair loss due to stress: how long does it last? Timeline from 2 to 6 months and when your hair will grow back

Hair loss due to stress usually lasts several months and almost always goes away on its own. After a heavy period, your hair often only falls out 2 to 4 months later, and that loss usually stops within about 6 months.^[1] Then the hair grows back, although it will take months before you really see it. Doctors call this telogen effluvium: many hairs stop growing at the same time and later fall out all at once. Does the loss last longer than 6 months, do you see bald spots or is your hairline receding? Then there is probably more going on and a visit to the doctor is wise. In this blog you can read how to recognize stress-related hair loss, what you can do yourself and when minoxidil is or is not suitable.

Can stress really cause hair loss?

Yes, stress is seen as a of the triggers of telogen effluvium, in addition to childbirth, high fever, surgery, significant weight loss and some medications.^[1][3] Normally most of your hair is in the growth phase. After a significant shock to your body, many hairs move on to the resting phase at the same time. Those hairs will remain there for a few months and then fall off. That is why the dropout is often only noticeable when the stressful period is behind you.

To be honest, the evidence for emotional stress as a cause is less solid than for childbirth or illness. A Dutch hospital leaflet on telogen hair loss writes that it is not certain whether emotional stress is a cause, and that no cause is found in about a third of people.^[2] Harvard research showed in 2021 in mice that the stress hormone corticosterone keeps hair follicles in the resting phase for longer.^[4] This makes a connection plausible, but the researchers emphasize that these are mice and that no treatment has yet been developed. occurs.

How long does hair loss due to stress last?

Most people go through a fairly fixed pattern. The times below are averages from Dutch and international sources; for you it may happen a little earlier or later.

If the loss lasts longer than 6 months, doctors call it chronic telogen hair loss. You mainly see this in women between 30 and 50 years old and it can go up and down for years.^[2] Then it makes sense to look for an underlying cause together with your doctor.

How do you recognize hair loss due to stress?

The most important feature: the hair becomes thinner all over your head, without bald spots.^[3] You normally lose up to about 100 hairs per day; Abnormal hair loss occurs when there are more than 100 hairs per day.^[1] With telogen effluvium there can be clearly more. It is especially noticeable when washing and combing.^[2]

How to distinguish stress hair loss from two other forms that are often confused:

The data in this table comes from Health and Science and DermNet.^[1][3] Do you see smooth bald spots, or areas with redness and flakes? Then it is not about stress hair loss and the doctor is the first step. If you have any doubts about your hairline, read our blog about hair loss in the fall and the signs that there is more going on.

Does your hair grow back after stress?

In most cases, yes. In acute telogen hair loss, according to the Amstelland hospital brochure, the head of hair grows out completely again, provided the trigger is not repeated.^[2] DermNet even paradoxically calls the loss a sign of recovery: the new hairs push out the old ones.^[3] Count on patience. Hair grows slowly, so it takes months before you see volume again.

There is one important exception. Sometimes a period of significant hair loss makes it visible that hereditary hair loss was already happening in the background. A study among 200 women after childbirth found that most of them had another form of hair loss in addition to telogen effluvium, often hereditary hair loss.^[5] DermNet also writes that repeated periods of telogen effluvium sometimes lead to hereditary hair loss in women.^[3] Does your hair not recover after a year, or do your inlets or crown remain thinner? Then that is a signal to look further.

What can you do yourself?

A treatment that accelerates the recovery from acute telogen hair loss does not exist.^[2] You can support your hair and scalp as best as possible:

• Be gentle with your hair. DermNet advises against combing, brushing or massage your scalp firmly.^[3]
• Eat a varied diet, with enough protein, vegetables and fruit. Eating less is itself a known trigger of hair loss.^[2][3]
• Have deficiencies checked. An abnormal thyroid or a deficiency of iron, vitamin B12 or folic acid can contribute; you need to have it corrected.^[3]
• Take the mental side seriously. Hair loss itself can cause a lot of worries, and that deserves attention.^[3]

Does minoxidil help with hair loss due to stress?

In case of pure stress hair loss, minoxidil is usually not necessary, because it repairs itself. The leaflet for minoxidil 5% foam also explicitly states that you should not use it if your hair falls out suddenly or in spots, or if the cause of your hair loss is unknown.^[6] So do not apply the product immediately if you suddenly lose a lot of hair.

Minoxidil is suitable if it appears that there is hereditary hair loss behind it: a receding hairline or thinning crown in men, or diffuse thinning hair in women. The effect has been proven for this and it is the first choice for women.^[1] You use it for a long time, and when you stop, the hair loss usually returns. In the first 2 to 6 weeks you may lose a little more hair; read our blog about minoxidil shedding. According to the leaflet, you can see results after about 2 months, sometimes only after 4 months.^[6]

When should you go to the doctor?

Go to the doctor in case of sudden or unexpected hair loss so that the cause can be investigated.^[1] This certainly applies if:

• you see bald spots, smooth or with redness and flakes;
• the loss lasts longer than 6 months;
• you also feel physically unwell;
• you recently started using a new medication;
• the stress itself is difficult for you. You can also contact your doctor for this.

The doctor can examine your hair, do a pull test and, if necessary, have blood drawn, for example for iron or your thyroid.^[2][3]

Frequently asked questions

How much hair loss per day is normal?

Up to about 100 hairs per day is normal. If you lose clearly more, doctors speak of abnormal hair loss.

Can stress make you go bald?

Stress hair loss usually does not make you permanently bald: the hair thins diffusely and then grows back. Bald spots or a receding hairline indicate another form of hair loss.

Why does my hair only fall out months after the stress?

Hair that enters the resting phase due to stress remains in place for a few months before falling off. As a result, the loss usually only starts 2 to 4 months after the stressful period.

Do hair vitamins help with hair loss due to stress?

Only if you really have a deficiency, for example of iron or vitamin B12, does supplementation make sense. Have this checked by your doctor instead of taking supplements at random.

How do I know if my hair will grow back?

You will then see short, new hairs along your hairline and parting, and the loss in the shower and brush will decrease. Volume returns slowly, because hair grows slowly.
