Stress and hair loss: how they are linked and what you can do

Stress and hair loss: what is the link?

Intense or prolonged stress can disrupt the natural hair cycle and cause more hair than usual to fall out a few weeks later. It is one of the most common causes of diffuse hair loss and, in most cases, it is temporary.

If in recent months you have noticed more hair on your pillow or brush after a period of exams, a job change, a bereavement or any situation that kept you on edge, it is probably no coincidence. Understanding how this link works is the first step to looking after yourself and keeping your expectations realistic.

The hair cycle and the role of cortisol

Hair grows in cycles, and sustained stress can push many follicles into the resting phase at the same time. When that happens, those hairs shed a few weeks later.

Each hair goes through three phases: anagen (growth, lasting years), catagen (transition, a few weeks) and telogen (rest, a few months, after which the hair falls out and makes way for a new one). Normally, only a small proportion of follicles are resting at any one time.

In a stressful situation, the body releases cortisol and other hormones. Occasionally this is a normal response, but when tension lasts over time it can upset this balance and increase the number of follicles entering the resting phase together.

Telogen effluvium: the hair loss most associated with stress

Telogen effluvium is diffuse hair shedding that usually appears around two to three months after a stressful episode. It is generally reversible once the cause is resolved.

That delay between the trigger and the shedding often makes it hard to connect the two. Unlike androgenetic alopecia, which affects specific areas such as the temples or crown, telogen effluvium spreads the loss across the whole scalp, so hair simply looks less dense overall.

Besides emotional stress, it can be triggered by an illness with fever, surgery, childbirth, a very restrictive diet or nutritional deficiencies. To learn about other causes, read our guide on why hair falls out in men and women.

How to tell if your hair loss is caused by stress

Stress-related hair loss is usually widespread, coincides (with a delay of a few weeks) with a tense period and does not leave specific thinning patches.

Other signs that often come with it are insomnia, tiredness or changes in appetite. On the other hand, if the loss is localised, progressive and runs in the family, androgenetic alopecia is more likely and should be assessed separately by a specialist.

Bear in mind that only a professional can confirm the cause: thyroid problems, low iron or other conditions can produce similar shedding.

Habits to manage stress and look after your hair

There are no magic formulas, but resting well, staying active and learning to manage tension support your overall wellbeing and, with it, help your hair get back to its rhythm.

• Get enough sleep: 7 to 9 hours, with regular hours.
• Exercise moderately on a regular basis, such as walking, swimming or yoga.
• Practise relaxation techniques, such as deep breathing or meditation.
• Cut back on stimulants, such as too much caffeine.
• Treat your hair gently: avoid pulling, very tight hairstyles and excessive heat.

It is also important not to become obsessed with counting hairs: anxiety about hair loss can become a new source of stress that feeds the problem.

Nutrition and supplements: what they can offer

A varied diet is the foundation; a food supplement can help you cover hair-related nutrients, but it does not act on the cause of stress or replace a diagnosis.

Ashwagandha is a plant traditionally used in Ayurvedic medicine as part of wellbeing routines, and its relationship with stress is a topic research is still exploring. If you are interested in this ingredient, you can find it in VitalizeNature Shilajit Original + Ashwagandha, a resin to dissolve in hot water or another drink that combines two traditional Ayurvedic ingredients. Find out more in our article all about ashwagandha.

Hair supplements such as Xpecia Hombre and Xpecia Mujer provide biotin and zinc, which contribute to the maintenance of normal hair, along with other nutrients and plant extracts. Xpecia Mujer also contains iron. If you are pregnant, breastfeeding or taking medication, check with a professional first.

When should you see a dermatologist?

See a dermatologist or doctor if hair loss is intense or sudden, lasts more than six months, appears in specific areas or comes with itching, pain or changes to the scalp.

It is also worth making an appointment if you cannot identify any stressful episode that explains it. A proper diagnosis rules out other causes, such as thyroid disorders or nutritional deficiencies, and helps plan the right approach for you.

In summary

Stress and hair loss are linked through cortisol and its effect on the follicle cycle, mainly via telogen effluvium. It is a common and usually temporary cause: managing stress, eating well and being patient is the most sensible approach while your hair returns to its normal cycle.

Frequently asked questions about stress and hair loss

How long after a stressful event does hair start falling out?

Shedding usually appears around two to three months after the stressful episode. This delay happens because stress pushes many follicles into the resting phase at once, and those hairs fall out weeks later. That is why it can be hard to link the hair loss to its cause.

Does hair lost to stress grow back?

In most cases, yes. Telogen effluvium is usually temporary and hair returns to its normal cycle once the cause of stress is resolved, although the process takes months. If shedding lasts more than six months or is very intense, see a dermatologist to rule out other causes.

How can you tell stress-related shedding from androgenetic alopecia?

Stress-related shedding is diffuse: hair looks less dense across the whole scalp, without specific thinning patches. Androgenetic alopecia, by contrast, progresses gradually in areas such as the temples or crown and often runs in the family. A dermatologist can confirm which one you have.

Which habits help when stress affects your hair?

Sleeping 7 to 9 hours, exercising moderately and regularly, practising breathing techniques or meditation and cutting back on caffeine. It also helps to treat your hair gently and not obsess over counting hairs, because anxiety about hair loss can become a new source of stress.

Do hair supplements help with stress-related hair loss?

A supplement does not act on the cause of stress or replace a diagnosis. What it can do is help you cover nutrients such as biotin and zinc, which contribute to the maintenance of normal hair, always alongside a varied diet and a healthy lifestyle.
