Did you know that a healthy mind is closely linked to healthy hair? Our hair's vitality and our mental well-being are interconnected, with stress and chronic emotional strain significantly impacting the appearance of our strands. Discover the correlation between hair thinning and stress, plus tips on how to manage it and help reduce hair shedding.

Stress Related Hair Loss

Can stress actually cause my hair to fall out? The short answer is yes. Hair loss due to stress is a common condition wherein an emotionally or physically stressful event disrupts the hair growth cycle. When we experience such distress, our bodies release hormones, such as cortisol (the stress hormone), which cause this disturbance.

Usually, about 10% of our hair is in the telogen (resting) phase. However, when stress occurs, it essentially shocks the hair follicle, triggering hairs to enter this phase prematurely. This typical type of hair loss, known as telogen effluvium, is characterized by sudden, widespread hair shedding.

The sebaceous glands become overactive, leading to scalp irritation and imbalance, which generates destructive enzymes that break down proteins essential to hair health, weakening hair follicles. And, the emotional upset of losing hair from stress, in and of itself, can compound matters.

How long after a stressful event does the hair loss start? Stress alopecia may begin anywhere from 2 to even 6 months after a significant stressor. Experiencing massive shedding? Think back to what happened a couple of months ago to help pinpoint whether stress is the reason for your hair loss.

What types of hair loss are caused by stress? In addition to telogen effluvium, other medical conditions related to stress may trigger hair fall.

• Alopecia Areata: In this autoimmune condition, the body attacks hair follicles, resulting in patchy, round bald spots.
• Trichotillomania: The urge to literally pull one's hair out is a compulsion caused by a genetic predisposition, environmental factors, and stressful events. This repetitive, stress-coping mechanism to handle emotions, anxiety, and even boredom, is often seen with anxiety, OCD, and depressive conditions.
• Cushing’s Disease: This adrenal gland condition, along with excess cortisol from stress, may lead to more stress and inadequate sleep, both of which are tied to hair loss.

There are other physical and emotional triggers related to hair loss:

• Physical stressors: Childbirth, surgery, significant illnesses, and weight loss are other factors that could cause stress-induced alopecia.
• Medications: Anti-inflammatories (NSAIDS), anti-seizure drugs, chemotherapy drugs, cholesterol-lowering medications, high blood pressure medications (beta-blockers, calcium channel blockers, ACE inhibitors), hormonal medications, and some antidepressants are linked with hair loss. Note: Do not discontinue any medication without first talking to your physician.
• Major life events: Stressors such as a cross-country move, breakups or divorce, death of a loved one, and unemployment are also associated with hair loss.
• Chronic insomnia: Regular, daily sleep disturbance can lead to higher stress levels, which can induce temporary hair loss. It can also aggravate hereditary hair loss in people predisposed to androgenic alopecia.

Genetic vs. Stress Alopecia

How can I tell if my hair loss is due to stress or genetics? Unlike genetic hair loss (androgenetic alopecia), stress-induced hair loss manifests as diffuse, overall shedding and hair thinning, sometimes in massive clumps. If you suddenly notice hairs on your pillow, a clogged shower drain, or a full hairbrush, you may be experiencing hair fall due to stress.

However, when men exhibit a distinctive pattern of loss in the shape of an “m” along the hairline or on the crown, or women notice their part widening and thinning on the top of their head, chances are that stress is not the culprit.

Regrowth + Timing

Will my hair grow back after stress-related hair loss? For telogen effluvium, the answer is generally yes, once the stress and other related underlying factors are managed. When a healthy routine is established and cortisol levels are restored, our bodies will function normally again.

How long does it take for hair to grow back after a stressful event? Patience is key here, as it can take from 6 to 9 months to experience significant regrowth. However, if stress is not managed, the condition may continue.

Does chronic (long-term) stress cause permanent hair loss? Not usually, as stress-associated hair loss is typically temporary. But left unchecked, high stress levels can harm your overall health, plus the ensuing cortisol spikes can contribute to male and female pattern hair loss.
