The Connection Between Stress and Hair Loss

Introduction

Hair loss is a common concern for many people, and while genetics and age play a significant role, another factor that is increasingly recognized is stress¹²³⁴⁵. This article will delve into the connection between stress and hair loss, providing an understanding of why it happens and how it can be managed.

Understanding Stress and Hair Loss

Stress affects the body in numerous ways, one of which is hair loss¹³. There are three types of hair loss associated with high stress levels: Telogen effluvium, Trichotillomania, and Alopecia areata¹.

Telogen Effluvium

In Telogen effluvium, significant stress pushes large numbers of hair follicles into a resting phase¹. Within a few months, affected hairs might fall out suddenly when simply combing or washing your hair¹.

Trichotillomania

Trichotillomania is an irresistible urge to pull out hair from your scalp, eyebrows or other areas of your body¹. Hair pulling can be a way of dealing with negative or uncomfortable feelings, such as stress, tension, loneliness, boredom or frustration¹.

Alopecia Areata

A variety of factors are thought to cause alopecia areata, possibly including severe stress¹. With alopecia areata, the body’s immune system attacks the hair follicles — causing hair loss¹.

The Role of Cortisol in Stress-Induced Hair Loss

When we experience stress, the body releases a hormone called cortisol⁵. This hormone can have a range of effects on the body, including on hair growth⁵. A major stress hormone produced by the adrenal glands, corticosterone, was upregulated by chronic stress; giving mice corticosterone reproduced the stress effect on the stem cells².

Managing Stress to Prevent Hair Loss

Stress and hair loss don’t have to be permanent. If you get your stress under control, your hair might grow back¹. If you notice sudden or patchy hair loss or more than usual hair loss when combing or washing your hair, talk to your doctor. Sudden hair loss can signal an underlying medical condition that requires treatment¹.

Conclusion

The connection between stress and hair loss is well-established. While acute stress boosts the immune system, chronic stress suppresses and over-activates the immune system, leading to inflammation⁴. Understanding this connection is crucial for managing both stress levels and maintaining healthy hair. Remember to always consult with a healthcare professional if you’re experiencing significant hair loss.
